A/C Signal: Description and Operation
A/C Request Signal
This signal tells the PCM when the A/C mode is selected at the A/C control head. The PCM uses this 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.
Refer to A/C Clutch Circuit Diagnosis for A/C wiring diagrams and diagnosis for the A/C electrical system.
