Towbar Diagnostics

After the installation of vehicle specific wiring kit, it is sometimes necessary to update the vehicle’s software to enable any inbuilt towing safety and comfort features when a trailer or caravan is connected.

Depending on the vehicle the tool will activate the following features:

  • Trailer Stability Program - detects any snaking motion from the trailer or caravan and bring it back under control using the brakes individually on the car.

  • Fog light cut off - turns the vehicles fog lights off when a trailer is plugged in.

  • Reversing sensor cut off - deactivates the vehicle reversing sensors when a trailer is plugged in.

  • Indicator bulb failure detection - detects if an indicator bulb is not working on the trailer.

  • Adaptive Air Suspension - automatically switches the suspension to towing mode when a trailer is connected. On some vehicles it will also stop the vehicle from lowering itself at higher speeds.

  • Electronic tailgate opening deactivation - automatically deactivates the electronic opening tailgate from the button on the key or inside the vehicle when a trailer or bike rack is plugged in. This avoids the tailgate being accidentally opened into a bike rack attached to the towbar.

Complete Diagnostics Remote Recoding

On some new vehicles it may be necessary to recode the vehicle remotely over the internet. Using Complete Diagnostics' remote coding app with the latest up-to-date software we are able to recode a wide range of new vehicles to enable any built in towing features.

Battery support

When recoding certain vehicles it is important to make sure the vehicle voltage is kept constant.

 

We use a Snap-on voltage stabiliser for any recoding to ensure the coding is completed without any drain on the vehicle battery.
