Park/Tail/Marker/License Lights

Battery positive voltage (B+) is applied at all times through RH rear junction block PARK LP Fuse to the Lamp Control Module (LCM). Under specific conditions, battery positive voltage (B+) is applied from the LCM through IP fuse block LH EXT LP Fuse and RH EXT LPS Fuse to the park/turn, tail/stop/turn, side marker, and license lights causing them to light. The conditions for turning on the park lights are:
^ the headlamp switch in the PARK or ON position.
^ the ignition switch is in the RUN position, the gear selector is not in the PARK position, and the ambient light sensor indicates darkness.
^ due to perimeter lighting.
