A/C Request Signal

This signal tells the PCM when the A/C mode is selected at the A/C control switch. The PCM uses this signal to adjust the idle speed before turning ON the A/C clutch. The A/C compressor will be inoperative if this signal is not available to the PCM.

For A/C wiring diagrams and diagnosis for the A/C electrical system, refer to A/C Clutch Circuit Diagnosis.
