Park/Side Marker/Tail Lamps

The park lamps, side marker lamps, and tail lamps are supplied power from two different circuits. When the headlamp switch is in the PARK, the park lamps input to the Lamp Control Module (LCM) is grounded. The LCM then applies battery positive voltage (B+) through the IP junction block LP PK L Fuse and LP PK R Fuse to the underhood lamp, the tail lamps, the side marker lamps, and the park lamps. Battery positive voltage (B+) is supplied via CKT 309 (BRN/WHT) to the RH park lamps and all lamps on the trunk lid. Power is supplied via CKT 709 (PPL) to the LH park lamps.
