Park Lamps

WARNING: This page is about a different variant/trim than selected.

The park lamps system includes the left (lighting) multi-function switch, the IPC and the BCM. The clearance (position) lamp bulbs in the upper cavity of each lower front combination lamp unit have a path to ground at all times through their connection to the headlight and dash wire harness. The headlight and dash wire harness has takeouts with eyelet terminals that are secured by screws to the front end sheet metal within the engine compartment. The park (tail) lamp bulbs in each rear lamp unit and the license plate lamps have a path to ground at all times through a takeout and eyelet terminal of the body wire harness that is secured by a screw to the body sheet metal within the passenger compartment.

The BCM monitors a hardwired input from the left (lighting) multi-function switch, then responds to this input by energizing or de-energizing high side drivers, which control battery voltage outputs to the appropriate lamps and bulbs through the proper park/tail/license/running lamp right and left circuits. The BCM also provides the appropriate electronic messages to the IPC to control the illumination and lighting level of the panel lamps.
