A/C Signal: Testing and Inspection
CIRCUIT DESCRIPTION Turning ON the air conditioning supplies ignition voltage to the A/C compressor clutch and to the
PCM to increase and maintain
idle speed.
The
PCM does not control the A/C compressor clutch. Therefore, if the A/C system does not function, refer to
Heating and Air Conditioning / System Diagnosis for diagnosis of the system.
