Variable Control Relay Module (VCRM)
VCRM interfaces with the Powertrain Control Module (PCM) to control cooling fan, A/C clutch control, A/C head pressure control and fuel pump operation. The VCRM also supplies power to the PCM and EEC-IV system.
NOTE:
Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce voltage signals monitored by the control unit. The second category covers OUTPUT SIGNALS, which are components controlled by the control unit.
