Fuel Pump Relay: Description and Operation

Constant Control Relay Module (CCRM).

Constant Control Relay Module

The 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:

-

Engine start-up.

-

Wide Open Throttle (WOT).

-

During engine low idle conditions.

-

Excessively high engine temperature.
