Park, Tail and Marker Lamps

The park lamps, including the license lamps, and rear door window switch backlighting are turned on when the headlamp switch is placed in the PARK, ON position or anytime the headlights are requested. The PK LP fuse in the fuse block - underhood - left supplies battery positive voltage to the LCM. When the headlamp switch is in PARK or ON, the park lamp switch signal circuit of the LCM has a ground path. The LCM provides battery positive voltage to the park lamp control circuit. When the park lamps and/or the tail lamps are ON, the LCM energizes the park lamp control circuit. Current flows from the LCM to the LP PK L fuse and to the LP PK R fuse in the fuse block - IP. From the fuses, the current flows to the park lamps. The left park lamps are grounded at G106 and G402. The right park lamps are grounded at G105 and G400. The LP PK R fuse supplies battery positive voltage to the license lamps and the right rear door window switch backlighting lamp. The license lamps are grounded at G400. The LP PK L fuse supplies battery positive voltage to the left rear door window switch backlighting lamp.
