The control unit must be coded according to the corresponding equipment in order for all functions to work correctly. For example, when retrofitting/removing trailer hitch, you have to code/decode on/off function for trailer for it to work correctly.
Note:
It is recommended to make a back-up of the configuration before coding in the new functions, see separate function.
Coding takes up to 2 minutes, during that time the diagnostic equipment may not be disconnected.
Coding shall be run in instruments and central electronics, for full functionality.
Test conditions:
Battery charger connected to vehicle.
Ignition on, engine off.
Procedure:
Start the function.
A dialogue box shows a scroll list.
Select the type of trailer function that has been installed/removed.
A dialogue box is shown, where you can choose to continue or cancel.
Coding takes up to 2 minutes, during that time the diagnostic equipment may not be disconnected.
The function is done.
If the function fails, check the test conditions and repair any faults.
