Connect the ISAT, contact ICE and read any trouble codes. Deal with trouble code B1311 if it has been generated. Then select the ISAT command "AC ON" in the activate menu and check that the compressor starts. Cars with manual AC: If the compressor starts, check the circuit between pin 64 of the ICE control module (AC input) and the AC button. Also check the circuit's power supply. If the compressor fails to start, continue with point 9. Cars with ACC: If the compressor starts, contact the ACC, obtain readouts of any trouble codes and rectify them. If the compressor fails to start, check the wiring between pin 38 of the ACC control module and pin 64 of the ICE control module for continuity.
