Air Conditioning Cycling Switch (ACCS) Circuit

AIR CONDITIONING CYCLING SWITCH (ACCS) CIRCUIT

The ACCS circuit to the powertrain control module (PCM) provides a voltage signal which indicates when A/C is requested. When the A/C function selector switch is turned on, voltage is supplied to the ACCS circuit at the PCM. Refer to Vehicle/Diagrams for vehicle wiring.

If the ACCS signal is not received by the PCM, the PCM does not allow the A/C to operate.
