A/C Request Signal
The A/C request signal indicates to the
PCM that an A/C mode is selected at the A/C control head. The PCM uses this information to adjust the
idle speed before turning ON the A/C clutch. If this signal is not available to the PCM, the A/C compressor will be inoperative. For a complete description of the PCM controlled portions of the A/C electrical system refer to PCM Controlled Air Conditioning.
