Fuel Tank And Lines - TDV6 3.0L Diesel (G2006336): Operation: Notes

The fuel pump in the fuel delivery module is supplied power via a fuel pump relay in the Rear Junction Box (RJB). The fuel pump relay is controlled by the Body Control Module/Gateway Module (BCM/GWM). The fuel pump relay is active when the ignition is in all power modes except for Power Mode 0 (OFF). The PCM is connected to the BCM/GWM to receive a 'wake-up' message. In the event of an accident the Restraints Control Module (RCM) outputs a crash signal to the BCM/GWM to disable the fuel pump relay.
