Fuel door release actuation is controlled by the following components.

Battery voltage for the coil side of the fuel door release relay is supplied through the Valet switch ( with the valet switch in the OFF position) by the ALDL fuse located in the Underhood Fuse (Bussed) Block. Battery voltage for the switch side of the fuel door relay is supplied by the Body fuse located in the Rear Fuse (Bussed) Block. When the fuel door release switch is momentarily pressed, it provides a ground circuit for the fuel door release signal of the Instrument Panel Module (IPM). When the IPM senses that the switch has been activated, it sends a Serial Data Class 2 message to the Rear Integration Module (RIM). The RIM then provides a ground circuit for the battery voltage from the ALDL fuse, the fuel door relay is energized, and battery voltage is applied through the switch side contacts of the fuel door release relay to the fuel door release actuator. The actuator is connected to ground through a ground splice pack located at the left rear corner of the rear compartment, near the left tail lamp connector..
