Constant Control Relay Module

PURPOSE
The Constant Control Relay Module (CCRM) interfaces with the EEC-V system to provide control for the cooling fan, A/C clutch and electric fuel pump. The CCRM also contains the EEC-V Power Relay which provides Vehicle Power (VPWR) to the Powertrain Control Module (PCM) and the EEC-V system. If any of the internal components of the CCRM fail, the entire unit must be replaced.
