Code trailer function

This function is used to code the trailer function.
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:
There must be a backup of the configuration from the BCMii/central electronics/body control module before coding the new functions into the instrument, see separate function.
Coding takes up to 2 minutes, during that time the diagnostic equipment may not be disconnected.
The coding must first be performed in the instrument and then in the BCMii/central electronics/body control module, for complete functionality.
