A/C Cycle Switch (ACCS)

The ACCS is a voltage input to the PCM which indicates when A/C is requested. When A/C demand switch is turned on, the cyclic pressure switch and the high pressure contacts of the dual function A/C Pressure Switch (ACPSW) are closed and voltage supplied to the ACCS circuit signal at the PCM. See CCRM circuit schematic in CIRCUIT TEST X in TESTS W/CODES article for more information.
