Park Lamps

When the headlamp switch is in the PARK position, the park lamps input to the Lamp Control Module (LCM) is grounded via CKT 308 (GRY/BLK). The LCM then supplies battery positive voltage (B+) via CKT 256 (PPL) through PARK LP Fuse 8C to the tail, rear side marker, and license lamps via CKT 9 (BRN). Battery positive voltage (B+) is also provided to the front side marker and park lamps. When the ignition switch is in the RUN position and the ambient light sensor indicates darkness, the LCM provides battery positive voltage (B+) to the park lamps, regardless of the position of the headlamp switch.
