The fuel pump relay, is controlled by the EEC module, which provides power to fuel pump under various operating conditions. When ignition is in "OFF" position, EEC power and fuel pump relay contacts are open. After engine starts, power to fuel pump is supplied through fuel pump relay. EEC module senses engine speed and shuts off fuel pump relay when engine stops.
The Constant Control Relay Module(CCRM)interfaces with the Power Control Module(PCM)to provide control of the cooling fan, A/C Clutch and fuel pump. The module also includes the electronic engine control(EEC)relay to provide power the PCMThe CCRM is a set of 4 relays in one module. The relays are :1. Relay for the PCM (Powertrain Control Module)2. Relays for the high and low radiator fan speeds.3. Relay for the fuel pump.4. Relay for the Air Conditioning clutch on the compressor.
