Fault-Tracing Information

There are two types of climate control, electronic (ECC) and manual climate control (MCC/STD).

Both systems have built in diagnostic functions, although only the electronic climate control system can communicate with the VIDA PC.

Electronic climate control (ECC) has a stageless setting blower fan switch and two Separate buttons for both A/C-and REC-functions.

Manual climate control has blower fan switch with fixed positions and a REC function button (cars with air conditioning (A/C), also a button for the air conditioning (A/C) function).
