This matching procedure must be carried out in the following cases:
Matching has the function of activating/deactivating fault recognition in the DDE for the assemblies multifunction steering wheel and air conditioning.
Example: If the speed control matching has the value "fitted" but no multifunction steering wheel is installed in the vehicle, fault recognition is active in the DDE and a fault code is always set in the fault code memory due to the absence of the multifunction steering wheel signal.
As from 09/98, whether a multifunction steering wheel or air conditioning system is installed/not installed is recognized automatically, i.e. matching is no longer necessary from this date on.
