What is recoding and why do I need it?

Today we seem to be driving computers on wheels that have clever features built in we don't even realise we have. After the installation of vehicle specific wiring kit or dedicated wiring kit, many vehicles need coding for the vehicle to recognise the fact that it is towing and enable certain inbuilt towing safety and comfort features when a trailer or caravan is connected.


Here at Towbex we have a diagnostic tool produced by Westfalia, the country’s leading diagnostic specialist, to allow us to carry out these software updates as the main dealers would.

This diagnostic tool works in conjunction with the vehicle specific wiring kit and will activate built in safety and comfort features in the vehicle such as Trailer Stability Program. This will detect any snaking motion from the trailer or caravan and bring it back under control using the brakes individually on the car.

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


  • Fog light cut off- This turns the vehicles fog lights off when a trailer is plugged in. 
  • Reversing sensor cut off- This deactivates the vehicle reversing sensors when a trailer is plugged in.
  •  Indicator bulb failure detection- Can detect if an indicator bulb is not working on the trailer. 
  • Hill start assist- A function to stop you rolling backwards on steep hills when towing extra weight behind you, this feature will keep the brakes applied until the throttle is applied, then they are released slowly to allow a smooth take off.
  •  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. Westfalia's diagnostic tool allows us to carry out the equivalent of the installation that the dealer would do at a fraction of the cost.




Vehicle Re-coding
Once a Vehicle specific wiring kit is fitted some vehicles will need the on-board car computer re-coded to be able to recognise you are now towing.

This diagnostic tool works in conjunction with the vehicle specific wiring kit and will activate built in safety and comfort features in the vehicle such as Trailer Stability Program. This will detect any snaking motion from the trailer or caravan and bring it back under control using the brakes individually on the car. 
Depending on the vehicle the tool will also activate the following features:


Fog light cut off- This turns the vehicles fog lights off when a trailer is plugged in. 
Reversing sensor cut off- This deactivates the vehicle reversing sensors when a trailer is plugged in.
 Indicator bulb failure detection- Can detect if an indicator bulb is not working on the trailer. 
Hill start assist- A function to stop you rolling backwards on steep hills when towing extra weight behind you, this feature will keep the brakes applied until the throttle is applied, then they are released slowly to allow a smooth take off.
 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. Westfalia's diagnostic tool allows us to carry out the equivalent of the installation that the dealer would do at a fraction of the cost.
Some vehicles need to be ''coded'' or programmed to activate the extra functions provided by the wiring loom, especially in the case of T-ESP (Trailer Stability Control) Parking sensors and fog cut out.

We have invested in the equipment needed to do this programming for you at the time that the towbar is fitted meaning that you don''t need to pay extra for your dealer to do it later.
