When the fuel door release switch is pressed, ground is applied on CKT 1447 (PNK/WHT) at terminal D6 connector 1 of the instrument panel integration module (IPM). The IPM will send a message via the class 2 data line to the rear interface module (RIM). The RIM applies ground to CKT 93 (WHT), with the valet switch in the ACCESS position, voltage is applied from the ALDL fuse 4, through the F/TNKDR relay coil. The relay energizes, the contacts close and voltage is applied from the BODY fuse to the fuel door release solenoid. The solenoid is connected to ground G402 via CKT 850 (BLK).
