When you press the release button on the Remote Keyless Entry (RKE) transmitter to open the rear compartment lid, a signal is sent from the Remote Control Door Lock Receiver (RCDLR) through circuit 377 to the Body Control Module (BCM). If the BCM receives a signal via Class 2 from the Powertrain Control Module (PCM) indicating the position of the park neutral position (PNP) switch is in Park, then the BCM will send a ground signal through circuit 253 to the rear compartment lid release relay. The relay receives power from the F7 - F8 fuse in the fuse block through circuit 1540. When the relay receives the ground from the BCM, the relay's internal switch closes sending B+ (via circuit 56) to the rear compartment lid latch release actuator. A ground is always supplied to the actuator through circuit 350. When B+ is received at the actuator through circuit 56, the rear compartment lid releases.
