A/C Compressor-On-Signal & A/C Compressor Cut-Out, Checking: Notes

NOTE: The A/C compressor ON signal increases the basic value for the Idle Air Control (IAC) valve, ensuring that the IAC valve remains in the center range of the control map. The A/C compressor cut-out signal switches OFF the A/C compressor for approximately 12 seconds, when the vehicle is accelerated from a standing start or a low speed.

NOTE: For location of ECM and harness connection. See COMPONENT LOCATIONS .
