A/C Cycling Switch (ACCS)

The ACCS circuit provides a voltage signal to the PCM that indicates when A/C is requested. When A/C demand switch is in the ON position, and both the ACCS and the high pressure switch (if equipped) contacts are closed, voltage is supplied to the ACCS circuit at the PCM. If ACCS signal is not received by the PCM, the PCM will not allow A/C to operate.
