Compressor Clutch Coil: Description and Operation
CONSTANT CONTROL RELAY MODULE (CCRM)
Constant Control Relay Module
The Constant Control Relay Module (CCRM) controls the A/C clutch and engine cooling fan motor operation based on signals received from the
A/C cycling switch, the A/C pressure transducer, and the Powertrain Control Module (PCM).
The CCRM deactivates the A/C clutch when signaled by the PCM. The A/C clutch is deactivated in this manner under the following conditions:
1. Engine start-up.
2. Wide Open Throttle (WOT).
3. During engine low idle conditions.
4. Excessively high engine temperature.
