How it works
Elecbrakes Sway Control
What is Elecbrakes SwayControl?
SwayControl is a stabilisation feature that continuously monitors your trailer’s lateral motion through your Elecbrakes EB2 or VM1. When instability or oscillation is detected, it applies progressive, symmetric braking across all brake magnets, integrating with your existing proportional settings to reduce sway. Because the intervention is symmetric, it works out of the box with most electric-braked trailers – no additional sensors or wiring changes required. It activates only when instability is detected.
With full system visibility through the Elecbrakes App and seamless Apple CarPlay and Android Auto integration, you can monitor performance, fine-tune settings, and track your Trailer Stability Gauge to better understand your trailer’s behaviour.
How do I get SwayControl on my EB2 or VM1 brake controller?
All Elecbrakes EB2 and VM1 brake controllers will have access to the new SwayControl feature (from 1st October 2025). If you already own an EB2 or VM1, you’ll receive a notification in the Elecbrakes App once your unit is ready for the update. Simply follow the in-app steps to install it. From 1st October, all new EB2 and VM1 units will come with SwayControl built in. Please note, our older brake controller product (ELBC2000) is not compatible.
Is SwayControl available on older Elecbrakes brake controllers? I
SwayControl is supported on EB2 and VM1 brake controllers. Older models (e.g., ELBC2000) are not compatible. You will need to upgrade to an EB2 or VM1 brake controller to access the new SwayControl feature.
If I already have a third-party sway controller, will it still work?
Yes, Elecbrakes SwayControl and third-party sway controller systems can remain installed together without conflict.
From the third-party system’s perspective, SwayControl output simply appears as a typical brake/override response from a brake controller. This means both devices will continue to monitor and control sway.
Based on our compatibility testing against popular sway control systems on the market, Elecbrakes SwayControl consistently intervenes earlier on minor sway, reacts stronger under more severe sway, and applies proportional braking until the trailer has settled.
If excessive sway correction or undesirable interactions are noticed, SwayControl can be turned OFF in the Elecbrakes app.
Do I need the Elecbrakes app?
Yes, for setup and adjustments. Use the Elecbrakes app for initial setup and any SwayControl‑specific adjustments (ON/OFF, Sensitivity, brake‑program tuning) and for firmware updates. The core SwayControl logic runs on the device itself, so it continues operating even if your phone isn’t connected.
Can I use the EB remote instead of the app?
Yes. Once enabled SwayControl will continue to function in the background when paired via the remote. You can use the EB Remote for day‑to‑day control and manual override, but you are not able to change SwayControl settings, adjust sway sensitivity, or view the Trailer Stability Gauge with the EB remote.
Will SwayControl still work if Bluetooth drops out?
Yes. The SwayControl logic runs on the device hardware; the app is for visibility and tuning only.
How do I turn SwayControl ON/OFF?
SwayControl is ON by default. You can turn it ON or OFF in two places within the Elecbrakes App.
Home Page:
• Press and hold the orange SwayControl icon to turn it ON/OFF.
• A single tap of the orange SwayControl icon will allow you to adjust the sensitivity level between low and high.
Program Settings:
• Go to the Settings page in your app and select the program you want to edit.
• Scroll down to the SwayControl section and toggle SwayControl ON/OFF for the program.
• You can also adjust SwayControl Sensitivity Level (Low to High).
SwayControl uses your active program’s Minimum/Forward response under the hood so behaviour matches your setup.
How does SwayControl interact with my brake program?
SwayControl respects your program’s Minimum and Forward response so intervention feels consistent with your tuning. You can also have custom preset SwayControl settings across all of all 5 programs, SwayControl ON/OFF and sway control sensitivity. Allowing you to dial in the perfect setting for your adventure.. Your tuning still defines baseline feel; SwayControl intervenes only when trailer instability is detected.
Where should I mount my brake controller for best SwayControl performance?
For optimal SwayControl performance, your Elecbrakes EB2 or VM1 should be mounted within 1m of the tow ball, with one flat face parallel to level ground. If you’ve installed your unit using the Elecbrakes plug & play adaptors or wired leaders, it’s likely already in the ideal location.
If your brake controller is mounted outside of the recommended zone, SwayControl performance may be oversensitive. If you require further guidance on the mounting location for your brake controller, reach out to our technical support team.
How do I know SwayControl is active?
- When SwayControl is active the central icon will turn red on the app, with the ‘SwayControl’ logo, the outside circle will indicate the sway control output.
- If SwayControl is ON, the SwayControl logo in the top left of the app will be a solid orange, indicating SwayControl is armed.
- If GPS permission has been enabled, speeds above 60km/h will arm SwayControl and if your speed falls below 50km/h, SwayControl will disarm.
- If using the EB remote, there is limited functionality, when SwayControl is active, the remote will simply indicate braking. Use the Elecbrakes app if you wish to adjust SwayControl settings in the programs.
What is the benefit of enabling GPS?
We’ve now integrated GPS into the app giving SwayControl superpowers. Arming SwayControl when you exceed 60km/h and automatically disarming below 50km/h, means SwayControl is there when you need it and gets out of your way when you don’t!
Note: The Elecbrakes App supports SwayControl within Apple CarPlay and Android Auto. While GPS enhancement isn’t currently available in CarPlay or Android Auto, you can still adjust sway sensitivity for each user program and switch SwayControl on or off. Future updates will include GPS enhancement to both Apple CarPlay and Android Auto.
Are SwayControl settings saved to my existing brake control programs?
Braking programs in the app have now been expanded to include SwayControl settings (adjust sensitivity and ON/OFF). You can define and save these settings to suit your trailer configuration and driving conditions. SwayControl uses your brake settings to tune its response.
Does SwayControl interfere with normal braking?
SwayControl is proportional and activates only when instability is detected, scaling with severity. One major advantage of an all-in-one solution is that the system delivers the exact response that you need – whether it’s precision braking, sway control, or both.
Does SwayControl replace safe loading & driving practices?
No – SwayControl is an assist! Correct loading, tyre pressure, speed and road awareness remain essential for safe towing.
Will SwayControl increase brake wear?
When SwayControl is active, these events are targeted and brief. Any additional wear on your trailer brakes will be minimal. Additionally, Elecbrakes SwayControl will notify you if the system is activating frequently and suggest solutions such as checking trailer loading or reducing your speed.
Installation Advice
How are Elecbrakes brake controllers powered?
ELBC and EB2: You will need to keep your headlights turned on at all times to provide constant power to the brake controller via the parking/tail light circuit. The only exception to this is when an auxiliary power circuit is present.
Ensure that your headlights are switched On and not to Auto, as many modern cars have an ‘Auto’ setting which provides Daytime Running Lights without necessarily providing a Park light output to the trailer.
VM1: The brake controller receives its power from an auxiliary input circuit, established during the installation process.
VM1 should not be connected to taillight circuits as some vehicles may register the electrical load as a trailer being permanently connected.
All Elecbrakes products are compatible with 12/24 volt power supply.
How can I add Auxiliary power to my tow vehicle socket?
When using a 7 pin plug/socket, an optional light duty auxiliary may be provided via Pin 2, suitable for up to 15 amp capacity when factoring the combined lighting circuit current draw.
This can be sourced from the tow vehicles battery or ideally, an ignition triggered fuse block. When routing an auxiliary supply to the vehicle socket, please ensure a 20 Amp inline fuse is installed.
For reference, wiring diagrams: https://www.elecbrakes.com/wiring-diagrams/
Vehicles equipped with a 12 pin socket may already have auxiliary power provided to Pin 9 and additional earth via Pin 10.
Does my EBR remote work with all Elecbrake brake controllers?
The remote will pair with earlier ELBC, current EB2 and VM1 brake controllers via bluetooth. Elecbrakes brake controllers can only be connected to one smartphone or remote at a time, ensuring full control is maintained by the user while in use.
If you try connecting via the remote and it isn’t connecting to the brake controller, this could be because the smartphone app is still running and connected in the background. In this case, you can close the Elecbrakes app on your smartphone before attempting to connect via the remote.
For EB2 and VM1, initial pairing and setup is required via the Elecbrakes App. To enable EBR:
- Select the “Settings” tab and scroll down to “Allow EB Remote”
For further information, please visit:
https://www.elecbrakes.com/wp-content/uploads/2023/10/Remote-User-Guide-2024.pdf
Please Note: You can use the EB Remote to easily adjust your braking response and access Manual Override. For the best user experience and system visibility, we recommend using the Elecbrakes app.
Does it matter if I dont install my brake controller parallel to the ground on my trailer?
You MUST ensure one of the brake controllers’ sides or faces is approximately parallel to the ground. This is required for calibration to ensure correct forward direction detection and accurate proportional control.
NOTE: This can be done by eye and does not require a spirit level or specialist tools.
Selecting a suitable mounting position
ELBC / EB2: The brake controller can be mounted directly to the trailer drawbar or crossbar, fastened with the 4x self tapping screws (supplied). For drawbars narrower than 90mm, a mounting plate may be required, or choosing an alternative location for the brake controller such as the underside of a tool box, floor of the trailer, or other accessory brackets.
The recommended mounting position is on the side of the draw bar, and within 1m of the tow ball.
VM1: Preferably mounted to the rear of the vehicle in the boot area, rear quarter, ute tray, or vehicle underside, fastened with 4x self tapping screws (supplied). A practical location for the vehicle must be selected to allow the provided cable to reach auxiliary power supply and vehicle trailer socket wiring.
Make sure one side of the unit is parallel to the ground and within 1m of the tow ball (i.e. behind the rear axle) for correct operation.
Refrain from mounting the brake controller inside a closed metal enclosure, as this may affect the Bluetooth signal reliability.
Mounting screws are provided which require tools to install/remove, alternative fasteners may be used such as Security screws or Pop Rivets, increasing the level of difficulty to detach. Alternatively, remove the brake controller while not in use for prolonged periods of time if the trailer is parked in a non-secure location.
How to mount the brake controller
For ease of installation, we recommend the following:
- Elecbrakes brake controller kit
- Electric drill + relevant PPE
- 4mm drill bit
- No. 3 phillips head driver bit
- Marker pen
- Lubricant
Once a suitable location for mounting is established, mark and pre-drill the mounting holes and screw the brake controller carefully in place.
NOTE: If required in an emergency, it is possible to temporarily secure the brake controller with cable ties/straps or other suitable fastenings, ensuring the brake controller cannot rotate or move while in use as this will affect the brake controllers calibration and output control.
How do I reset the brake controller calibration when installing on another trailer?
To reset and re-calibrate the brake controllers angle using the Elecbrakes App, follow these steps:
- Unplug the brake controllers 6 pin square Deutsch plug and unscrew the brake controller.
- Rotate the brake controller 90° or 180° from its starting orientation and place the brake controller on a flat surface.
- Plug in the Deutsch connector and power up to establish pairing via the App.
- Viewing the ‘Data’ tab, under Accelerometer information the ‘Angle’ should now indicate ‘Auto’, this indicates the brake controllers’ angle has reset.
- Unplug the Deutsch connector and re-secure the brake controller to its intended location.
- Ensuring the trailer is on relatively flat ground, plug the Deutsch plug connector in and check the Data > Angle still shown as ‘Auto’.
- Driving the trailer in the straight ahead direction of travel and applying the brake pedal once or twice will allow the brake controller to register its direction of travel.
- The ‘Angle’ should now register an angle in degrees, indicating brake controller calibration is complete.
- Proceed to adjust the user defined settings as required.
Howe to test the brake function whilst stationary/wheels off the ground?
For testing purposes, it may be necessary to adjust the minimum (static output) brake response temporarily to a higher value. This will influence the brake response while the trailer is stationary, providing a suitable test for wheel lock-up point if the trailer wheels are off the ground. Note – ensure that the vehicle lights are switched on during testing and use (ELBC and EB2 only).
- ELBC: Via the App, when applying the Manual Override or via brake pedal response, it may be possible to hear the brake magnets buzz/humm as they apply while the vehicle is stationary.
- EB2 / VM1: Via the App, when applying the brake pedal, it is possible to view the ‘Data’ tab > Outputs. The app will show both the Voltage output to the brakes and the current draw from the magnets.
Installation Types
EB2 vs VM1 - Which type should I choose?
Elecbrakes offers two top-tier options: the EB2 Trailer-Mounted Brake Controller and the VM1 Vehicle-Mounted Brake Controller. Both are designed with unique benefits to cater to your specific towing needs, whether you’re using multiple vehicles or trailers.
With the EB2 mounted on your trailer, any vehicle can tow it without needing a brake controller installed. On the other hand, the VM1 is installed in your vehicle, allowing you to tow multiple trailers with a single vehicle.
The following comparison will help you understand the key differences and features between the EB2 and VM1, so you can confidently select the best brake controller for your setup
Which type of trailers do Elecbrakes brake controllers work with?
Elecbrakes brake controllers are suitable for all trailers equipped with Electromagnetic brakes up to 4500 kg GTM, this includes but not limited to: Box/Goods trailers, Caravans and Campers, Car carrying & Flat top, Horse floats and more.
- For ELBC and EB2 when powered via brake and tail light circuits only – up to 2 braked axles (16A output)
- For All Elecbrakes brake Controllers, when provided with a 12-24V DC dedicated power supply – up to 3 braked axles (24A output)
All Elecbrakes brake controllers with integrated SwayControl may be installed in conjunction with electric over hydraulic brakes, so long as the hydraulic actuators’ installation requirements are met (check your hydraulic actuator installation manual for requirements).
Electric over hydraulic brakes are commonly found in use on Marine applications such as boat trailers, allowing the trailer axles to be submerged when loading/unloading.
What else is required for a boat trailer equipped with Electric-Hydraulic brakes?
Most common Electric-Hydraulic actuators require a Service brake input for proportional control. This is provided by the Elecbrakes brake controller via the blue service brake wire.
In addition, the actuator will require its own power/earth circuit to operate.
Please refer to the manufacturer’s documentation for the hydraulic actuator to confirm the peak current draw specifications. Depending on the brand/specifications, this may be greater than 30 amps, requiring a separate Anderson plug / Battery power source or other.
To clarify, Elecbrakes brake controllers do NOT supply the operating power to the actuator, only the braking response via the service brake circuit. If you are unsure whether you have a suitable power supply for your actuator please contact trailer manufacturer, actuator supplier, or reach out to our customer service and technical support team.
Are third-party Sway control systems compatible with an Elecbrakes brake controller?
Historically, most commonly installed sway control systems are compatible with the Elecbrakes brake controller service brake output.
As per the manufacturers specifications, some third party sway control systems may require an auxiliary power supply for primary function, followed by a suitable service brake signal to ‘wake up’ the system. Once the system is awake, it will allow the pass through of the service brake output, as confirmed when testing slow speed brake application.
Due to ADR compliance requirements, Service brake control takes priority and compatibility testing is generally completed by the sway control manufacturers.
Which Eeckbrakes adapter should I purchase & install with my EB2?
You must choose the appropriate Elecbrakes Adaptor based on your Tow vehicles’ trailer wiring socket and Trailer plug. The differences are in the shape and pin count.
Start by confirming the socket type fitted to the rear of the tow vehicle, then selecting the trailer plug type.
Elecbrakes provide an adaptor for each combination of commonly available plug and socket, allowing you to connect your vehicle to your new trailer, or vice versa, potentially without changing the plug or socket on your vehicle or trailer. When towing with multiple vehicles, it may be necessary to have more than 1 adaptor type on hand for installation to suit different combinations.
Some combinations will allow cross use, for example:
- Vehicles equipped with a 12 pin flat socket can accept a 12 pin flat or a 7 pin flat adaptor/trailer plug. However, vehicles equipped with a 7 pin flat socket will not accept a 12 pin adaptor/trailer plug.
Note: The VM1 does not require an Elecbrakes plug & play adaptor. The brake controller is installed using the provided 1.5m wired leader. Refer to VM1 Technical Manual for further information.
What if my trailer has a 12pin plug or anderson plug for accessories installed?
When advised by your trailer manufacturer of accessories installed that require an auxiliary power/earth supply, or, if the trailer is equipped with a 12 pin plug, it may require auxiliary circuits to be provided via the tow vehicle / socket. The additional auxiliary circuits may be added to the tow vehicle via pins 8-12.
In this scenario, we recommend the use of a 12 pin to 12 pin adaptor to allow throughput of the auxiliary circuits.
Reference to our 12 pin wiring diagrams: https://www.elecbrakes.com/wiring-diagrams/
In some cases, an Anderson plug may be required if the accessories installed have a current draw exceeding 30 amp peak. Please follow the manufacturers recommendations to add the required Anderson plug/circuit.
WARNING – When working with any additional plugs for auxiliary power on the trailer, you MUST ensure that the earth returns for the accessories are separated from the trailer lights and service brake circuits. If your accessories have a shared earth return, it will be possible to overload the earth circuit on one or either of the plugs, should you have a poor earth connection due to corrosion or dirt buildup.
Can i use a 7 pin to 12 pin adaptor?
While it is possible to utilise a 7 pin to 12 pin adaptor to enable the lighting circuits/service brake function, any accessories wired via Pins 8-12 on the trailer will not be operational in this scenario.
An optional light duty auxiliary may be provided via Pin 2, suitable for up to 15 amp capacity when factoring the combined lighting circuit current draw.
Can the ELBC / EB2 brake controller be hard-wired to the trailer?
It is possible to hardwire an Elecbrakes Trailer-Wired-Leader (TWL) directly to the trailer plug or harness, taking note of the pin number and colour coding as per our wiring diagram:
https://www.elecbrakes.com/wiring-diagrams/
Within the trailer plug that connects to the tow vehicle socket, the service brake (blue wire) must be joined to create a closed circuit from the brake controller (blue wire) to the brake magnets via the trailer harness (blue wire).
Taking note to not connect this to Pin 5 within the plug. This will ensure the brake controller remains in control of the service brake circuit without any external influence from different tow vehicles.
Which adaptor should I use if both tow vehicle & trailer have a 7 pin small round?
The design of a 7SR socket includes mounting tabs to support its bulkier fittings, which can lead to a heavier adaptor connection and reduced connection quality during use. For this reason, Elecbrakes does not offer a small round-to-small round adaptor in our current product range. Instead, we recommend either a wired leader installation or replacing the small round plug/socket with a flat-type arrangement.
Vehicle Compatibilty
Is the system comaptible with my tow vehicle?
Yes, Elecbrakes brake controllers are designed to function with 12v and 24v vehicles registered in Australia / New Zealand with respect to National standards and applicable ADR’s. This includes modern vehicles equipped with trailer wiring modules and earlier vehicles with fused circuits which are designed to meet the same national standards and ADRs for towing applications.
Is it possible to use Elecbrakes brake controller in a 24V vehicle?
Yes! Elecbrakes brake controllers accept both 12 and 24 Volt DC input power. The brake controller will regulate the 24V input, managing a 12V variable output for proportional control of the service brake circuit.
Is the system compatible with 24v to 12v converter?
Elecbrakes Brake Controllers are guaranteed to work when provided with a 12 or 24V DC input power source. Elecbrakes Brake controllers may work with various aftermarket 24V-12V step-down converters, depending on the model.
Please refer to the voltage converters technical manual to ensure compatibility.
If you are unsure if the system is functioning correctly with a voltage converter installed, a DC power supply should be provided to the brake controller via the Auxiliary input circuit.
What if my car has LED lights?
Vehicles factory fitted with LED lights will provide separate circuits for the vehicle lighting and trailer lighting output.
Vehicle sockets installed during factory fitment or Third party installation follow national standards such as AS4177.5-2004, requiring the appropriate gauge wiring / fuse to accommodate the circuit amperage rating.
What if my trailer has LED lights?
At times, trailers equipped with LED lights may not be detected by some late model tow vehicles when hitched/connected. This is generally due to low current draw in comparison to trailers fitted with incandescent lights.
The vehicle may remain in a low voltage / PWM output state whereby it pulses a low voltage (est. 4-8v range), without changing over to a full 12v output.
Some vehicle manufacturers produce wiring harnesses or adaptors to resolve this issue, usually incorporating resistors which causes the vehicle to detect the trailer and switch the output to a 12V DC source. While it may be possible for the trailer’s LED lights to function off a low voltage input, they may be flickering and not always visible to the naked eye.
Elecbrakes brake controllers require a minimum input voltage of 10V for consistent operation and functional output response.
What if my tow vehicle already has a brake controller installed?
In most instances, ensuring the in-car system has been adjusted to 0 will result in no conflicting signals reaching the trailer brakes.
ELBC / EB2: when installed using an Elecbrakes adaptor, the service brake circuit will receive input from the Elecbrakes brake controller only. The adaptor will have Pin 5 terminated on the vehicle side to prevent other signals reaching the trailer brakes.
Trailer wired leader: As per our wiring diagram: https://www.elecbrakes.com/wiring-diagrams/
The leader should be joined directly to the trailer’s service brake circuit only, keeping this circuit separate from Pin5 to prevent other signals reaching the trailer brakes.
VM1: When connecting the VM1 wiring to the tow vehicles socket, any existing wiring connected to Pin 5 should be removed and terminated, ensuring the only output applied to Pin 5 is from the Elecbrakes brake controller.
Is the system suitable when towing behind an EV or Hybrid vehicle?
Yes, the system is suitable for use with EV and Hybrid vehicles.
The vehicle socket installed during factory fitment or third-party installation follows national standards to provide the appropriate gauge wiring / fuse to accommodate the trailer circuits. Electric vehicles and Hybrid vehicles will maintain separate circuits for the vehicle lighting and trailer lighting output in a similar fashion to Petrol or Diesel tow vehicles.
What if the vehicle has Adaptive Cruise Control or Accident Mitigation?
Elecbrakes brake controllers provide a brake output response when receiving a control signal from the tow vehicle in the form of the brake light circuit becoming active and the rate of deceleration detected.
While driving with adaptive cruise control active and the vehicle detects a scenario requiring a partial deceleration, Petrol or Diesel vehicles may utilise a form of compression braking to partially slow the vehicle, whereas Electric or Hybrid vehicles may utilise regenerative braking function. If compression or regenerative braking is sufficient to slow the vehicle without the use of the vehicle’s hydraulic brakes, the brake light circuit will not become active.
When a greater rate of deceleration is required, the vehicle will proceed to apply the hydraulic brakes to assist in slowing the vehicle, further resulting in the brake lights becoming active, triggering the brake controller to respond.
Modern vehicles equipped with accident mitigation systems are designed to detect obstacles and respond accordingly, in some scenarios this may involve applying the vehicle brakes to reduce or avoid an accident. In this instance, the brake lights will become active, triggering the brake controller to respond.
Safety
Is it legal in all states to use the Elecbrakes app whilst driving?
Depending on state specific laws, exemptions may apply to safe mobile phone use as a driver’s aid whereby the mobile phone must be secured in a cradle fixed to the vehicle. Elecbrakes App is now also compatible with Apple Carplay and Android Auto equipped vehicles to further support this, please check with your local/state laws as they are updated on occasion.
User defined program adjustments via the App or EBR remote should be altered once the vehicle comes to a complete stop. The settings adjusted, based on trailer feedback, will be saved to the brake controller and will continue to respond to the vehicle control signal under normal braking application.
Manual override function is a feature included in the app based on customer response and not an ADR compliant function of the brake controller. Where state laws stipulate against the use of a mobile device as a driver’s aid, if Apple CarPlay / Android auto is not equipped to the vehicle, users may choose to purchase an Elecbrakes EBR remote to utilise this function.
Are Elecbrakes brake controllers suitable to meet registration requirements?
Yes, Elecbrakes brake controllers were developed to work in conjunction with the trailer’s braking system to meet ADR 38/05 requirements.
When trailers visit an authorised inspection station for safety check, the trailer is directly being assessed for compliance & safety, not the brake controller.
This is due to the fact the Road Vehicles Standards Act – 2018 applies to vehicles imported or manufactured, to be registered and driven on roads within Australia. The registry of approved vehicles is maintained using a VIN number which further identifies the applicable ADR’s for compliance and assessment.
Adhering to ADR 38/05 rules and regulations, Elecbrakes provide a solution for customers requiring a brake controller to operate the Service Brakes fitted to their ADR/RVS compliant trailer.
What is ADR 38/05?
Trailers exceeding 750kg GTM up to 2000kg GTM must be equipped with an efficient service brake system whereby the braking force can be progressively increased and decreased by means of the ‘Control Signal’ from the towing vehicle. Whether this be inertia based mechanical or electro-magnetic brakes.
Trailers ranging from 2000kg to 4500kg GTM must be equipped with an efficient service brake system that must operate on all wheels.
Every trailer having a Gross Trailer Mass over 2 tonnes must ALSO be equipped with an efficient Emergency Brake System (Break-away system) which is a separate function to the brake controller and not part of our product range. The Break-away function must be capable of automatically applying the trailer brakes for at least 15 minutes in the event of the trailer accidentally becoming disconnected from the tow vehicle.
Reference: https://www.legislation.gov.au/F2018L00692/latest/text
How do Elecbrakes brake controllers function to meet ADR 38/05 requirements?
The below statement offers clarification around ADR 38/05 and how Elecbrakes brake controllers were developed to work in conjunction with the trailer’s braking system.
The following ‘Control Signal’ is used by Elecbrakes brake controllers to engage and modulate the trailer brakes:
The voltage that is switched on for the brake lights when the tow vehicle brake pedal is depressed, is measured by the brake controller via the hardwired connection to the trailer brake light circuit.
The deceleration of the vehicle and trailer combination which is measured directly by sensors inside the brake controller.
During ‘normal operation’, the braking force is increased and decreased by means of the ‘control signal’ defined above. When the brake light voltage turns on, the brake controller knows that braking is required, and the force applied by the tow vehicle brakes tells the brake controller how much additional proportional braking force is required. The trailer brake force is varied by the brake controller in direct proportion to the measured deceleration, and responds to changes in braking force 1000 times a second (1ms response time). The ability of the brake controller to operate in this manner is in no way dependent on an active Bluetooth connection.
Brake feel can be adjusted through Bluetooth connectivity using the Elecbrakes App or EBR Remote (if purchased separately). This allows the driver to tailor the response by making changes to the ‘minimum’ and ‘forward’ parameters, which are saved within each of the 5 user defined programs tailored to specific driving conditions.
If the Bluetooth wireless connection disconnects at any time, the last saved parameters for the selected program are used by the brake controller. Assuming the brake controller remains powered, Bluetooth connection is re-established automatically and seamlessly.
Is the product registered under the Road Vehicles Standard Act - 2018?
Under the Road Vehicle Standards Act 2018 – current CRN / SARN approval scheme, there is no mandatory requirement for brake controllers to be type approved: https://www.infrastructure.gov.au/infrastructure-transport-vehicles/vehicles/rvs/component-type-approvals
Does my trailer need a break away system?
As per ADR 38/05, in Australia, every trailer having a Gross Trailer Mass over 2 tonnes must be equipped with an efficient Emergency Brake System (Break-away system), which is a separate function to the brake controller and not part of our product range. The Break-away function must be capable of automatically applying the trailer brakes for at least 15 minutes in the event of the trailer accidentally becoming disconnected from the tow vehicle.
How will my trailer brakes function during a stationary braking test?
For registration inspection purposes, when testing the trailer braking function/efficiency on a rolling road or with the wheels suspended, when the trailer is stationary it may be necessary to increase the Static output from the brake controller (Minimum %) when no inertia or deceleration is present.
If there is a Program not currently in use, it may be suitable to adjust settings and re-name the program for future inspection testing. If all programs are in use, ensure the original applied settings are returned after testing complete.
Excessively high settings may cause a harsh response/wheel lockup, progressively adjusting the Minimum% response to a higher value to achieve the desired result.
Technical Specs
Product Compliance
Elecbrakes EB2 and VMI hold the following product compliances:
What is the minimum voltage required for the system to function?
Elecbrakes brake controllers are compatible with 12V and 24V DC vehicles, requiring a minimum input of 10V. The functional input voltage ensures that there is adequate power received from the tow vehicle to engage the brakes appropriately.
3-Axis Accelerometer - how does it work & what does it do?
When mounting the brake controller parallel to the ground and powering up the brake controller, the on-board 3 axis accelerometer senses Gravity and registers the Orientation axis (which face is up).
During the initial test drive, upon the first or second brake application the brake controller will calculate the forward direction of travel forces, registering the device Angle in degrees.
If the brake controller is installed on the A-frame/Drawbar, it will mix these two remaining axis inputs to calibrate to the forward direction of travel.
Once calibrated, the brake controller will continue monitoring changes in deceleration + inclines/declines to proportionally adjust the required braking output.
EB2 & VM1 - Safety protections & notification
In the case of one of the safety critical events below being triggered on the brake controller, a push notification will be sent to your phone via the app alerting you of the potential issue. This means total confidence in your setup, quick and easy troubleshooting and unparalleled peace of mind whilst towing.

The EB2 / VM1 have integrated short circuit protection meaning in the case of a wiring or system hard fault the short circuit protection will trigger disabling the brake controller output. This will occur for currents greater than 32A and will trigger in less than 32µs.
Thermal protection
Thermal protection algorithms ensure advanced thermal management in the case of a system fault whilst still enabling the brakes to be engaged. In practical terms, this means that in circumstances where the brake controller is overheating due to a fault or improper use, it will continue to function to some degree in order to maintain braking output.
Under-Voltage Lockout (UVLO)
EB2 / VM1 require a minimum input of 10V to turn on and a minimum input of 9V to remain on. This ensures that there is adequate power received from the tow vehicle to engage the brakes appropriately.
NOTE – Some 24V to 12V step down converters drop the output voltage below these critical thresholds. Please ensure your step down is working correctly.
Over-Voltage Protection (OVP)
Actively protects against high voltage transients common in noisy automotive systems.
Bluetooth Connectivity
What is Bluetooth?
Bluetooth is a short-range wireless communication technology that allows devices to exchange data over a short distance, enabling seamless interaction when sending and receiving data or providing feedback to the user in real-time.
How do I pair via the Elecbrakes app?
• EB2 / VM1: You must use the app on your smartphone during the initial setup phase. To download the app simply search ‘Elecbrakes’ on the play store or app store, if your brake controller is accessible you can simply tap your NFC enabled device to the Elecbrakes logo on the housing.
• Opening the app will prompt the onboarding process, leading you to a Welcome page, where you will choose your brake controller.
Ensure the tow vehicle headlights are turned on to enable an active bluetooth connection.
• If your brake controller is an EB2, simply choose the Elecbrakes EB2 image.
• When prompted “Tap to Add”, proceed to tap your phone again on the EB2 housing to pair your device.
Alternatively, you can add the device via bluetooth from the driver’s seat of the vehicle, by selecting ‘Search Manually’.
• Follow the remaining steps of our onboarding in the app to confirm brake pedal response and proceed to adjust your settings.
Can you connect two devices to one Elecbrakes controller simultaneously?
• The short answer is no, Elecbrakes is engineered to allow only 1 user interface at a time.
• To switch between devices, selecting the ‘Devices’ tab in the app and pressing the orange button to the left of the device name will disconnect or reconnect depending on the current connection status.
What happens if Bluetooth disconnects?
Assuming the brake controller remains powered, if the Bluetooth wireless connection disconnects at any time, the brake controller and SwayControl logic will continue to function and provide brake output using the last saved parameters for the selected program. Bluetooth connection is re-established automatically and seamlessly almost instantly.
If the Bluetooth connection drops for longer periods of time (i.e. disconnect / poor connection), the app will revert to ‘searching’ or may prompt a ‘Low voltage input’ warning. The driver should safely pull over and check the physical wiring connections, as any type of power loss will generally affect trailer light function and brake response. This feedback response acts to notify the driver of a possible issue and once restored, pairing will resume connection and normal operation.
Confirm your EB2 is running the latest firmware and check for updates via the app settings tab. Firmware updates on all new models allow bluetooth to maintain an active connection when receiving only 5-6V, assisting the diagnostics process within app Data. Note: Functional voltage (>10V) is required to resume normal operation / brake response.
Using maps/calls while app in use
When using a mobile phone and minimising the Elecbrakes app to bring another app to the main screen, the app will maintain an active pairing in the background. In this scenario, the brake controller will continue to respond to the vehicle’s “control signal” and apply brake response when requested.
Using the phone’s active task list to switch back to the Elecbrakes app will re-enable access to the app / settings / override.
With the use of Android Auto or Apple CarPlay, many vehicles offer quick access to toggle between the most recently used apps, such as Maps / Calls.
Can my phone run Elecbrakes app?
Elecbrakes app is compatible with:
• iPhone – IOS 15.0 or later
• Android 10 or later
When accessing your app store to search for ‘Elecbrakes’ and selecting ‘download’, a notification may indicate if your device is not currently suitable to download and install the app.
Some devices may require a software update before allowing the app to download while others may have a software or hardware limitation preventing this. Please access your phone settings and check for any available software updates, completing as necessary.
My phone/app has been updated & I cant find my brake controller anymore?
Device operating systems updates can either improve or degrade device performance depending on factors like optimisations, new features, compatibility and security protocols. Apps are untouched by the operating system update process.
After completion of the device’s software update, if the Elecbrakes app operates in an unusual manner or is not pairing to the previously paired brake controller it may be necessary to reinstall the Elecbrakes app. During the uninstall / reinstall process, check the phones Settings > Bluetooth > Previously paired devices list, ensuring any previous EB products are removed from this list before opening the app to establish a new pairing.
Elecbrakes App updates often include optimisations and new features that are thoroughly tested with all existing devices to ensure compatibility across both earlier and newer versions of our brake controller products.
Apple CarPlay & Android Auto
What is it & how do I connect?
Offering a user-friendly interface, Apple CarPlay and Android Auto display an optimised version of the Elecbrakes app via your mobile phone device to your car’s infotainment system, Wireless or Wired access is dependent on vehicle model.
Does Apple Carplay or Android auto support the earlier ELBC or current EB2/VM1?
All Elecbrakes brake controllers actively paired via the Elecbrakes app can be used with Apple CarPlay and Android Auto.
Can i use the Elecbrakes app in split screen with other apps?
As the Elecbrakes app functions as a drivers’ aid, it will not allow split screen operation. You will be able to toggle between apps via the quick access panel, or your app list as required.
How can I add the Elecbrakes app to the quick access panel?
For more information on how to use the Apple CarPlay or Android Auto features refer to our user guide to get all the tips and tricks.

Tech/Warranty Help
How do I test if the brakes are working - Stationary / Test drive?
For DIY enthusiasts or trailer repairer’s, on occasion it may be necessary to test the trailer brakes while the wheels are in the air or the trailer is stationary.
Simply powering up the brake controller and pairing via the app, it is possible to temporarily adjust the Minimum % response to a higher value, creating a static output for testing.
• ELBC: Via the App, when applying the brake pedal or manual override, it may be possible to hear the brake magnets buzz/humm as they apply while the vehicle is stationary.
• EB2 & VM1: Via the App, when applying the brake pedal or manual override, it is possible to view the “Data” tab > Outputs. The app will show both the Voltage output to the brakes and the current draw from the magnets.
NOTE: with higher % applied for testing, if the current draw indicates 0.00-0.01A, there may be an open circuit or poor connection
Can I check if the brake controller has suitable ower/earth at the Deutsch plug?
If you have access to a multimeter, it is possible to confirm earth & voltage present to the brake controllers Deutsch plug by following the below steps. The brake controller requires a minimum input of 10v to enable pairing or brake response, ideally registering 12v+ with the vehicle idling.
With the adaptor and brake controller connected to the tow vehicle + ignition and headlights on:
• Probe the Earth (white wire) and the Tail light (Brown wire) = V
• With brake pedal depressed – Probe Earth (white) and Brake light (Red wire) = V
If the voltages are fluctuating or below 10v, there may be a poor connection at the adaptor/plug/vehicle socket. If after checking the pin terminals are free of corrosion and pins splayed, further investigation into the vehicles wiring may be required by an Auto Electrician.
Why are my brakes pulsing/harsh & my app/EBR has disconnected?
If the EB2 or ELBC brake controller does not receive a stable / functional input voltage from either the Tail light circuit or Auxiliary circuit, the brake controller will not maintain bluetooth connection to the App or EBR.
In this scenario, pressing the brake pedal in the tow vehicle may result in the brake controller receiving a functional input voltage from the Brake light circuit.
This will trigger a brake response/output from the brake controller in a reduced state, providing haptic feedback to the user in the form of a pulsed brake output. This response may be more aggressive than typical to prompt the user to pull over and assess the situation before proceeding.
What is the power test & when should I use it (tail-lights powered EB2)
The Power Test – available on the app home screen – is a quick pre‑trip check for EB2 setups powered from the vehicle’s tail‑light circuit (i.e., when not using a dedicated auxiliary feed). Because SwayControl can engage before the vehicle’s brake lights are on, an EB2 running on light‑circuit power supplies the trailer brakes from that same circuit. This SwayControl‑specific test measures your vehicle–trailer power characteristics and sets a suitable maximum brake output for that circuit, helping deliver confident, consistent assistance on light‑circuit power. If your EB2 is supplied by a dedicated auxiliary feed, running the Power Test isn’t necessary (though it remains a useful check).
