Refrigerant Pressure Sensor / Switch: Description and Operation
Air Conditioning (A/C) Cycling Switch
AIR CONDITIONING (A/C) CYCLING SWITCH
The A/C cycling switch may be wired to either the ACCS or ACPSW PCM input. When the A/C cycling switch opens, the PCM will turn off the A/C
clutch. For information on the specific function of the A/C cycling switch, refer to Heating and Air Conditioning. Also, refer to the applicable
Vehicle/Diagrams for vehicle specific wiring.
If the ACCS signal is not received by the PCM, the PCM circuit will not allow the A/C to operate.
Some applications do not have a dedicated (separate) input to the PCM indicating that A/C is requested. This information is received by the PCM
through the communication link.
