Perimeter Lighting

Perimeter Lighting provides a personal security feature by illuminating all exterior lights on the vehicle exterior for 15 seconds when the keyless entry transmitter is used to unlock the doors and it is dark outside. The backup lights, headlights, park lights and cornering lights will come on.

When the UNLOCK button on the keyless entry transmitter is pressed, the Remote Function Actuator (RFA) module grounds CKT 624 (BLK/WHT) to the Lamp Control Module (LCM) perimeter lighting input. The LCM then provides battery positive voltage (B+) to the headlamps, park lamps. Battery positive voltage (B+) is supplied through the IP fuse block PERIM LP Fuse and CKT 1654 (TAN) to the perimeter lighting relay. The RFA provides ground for the perimeter lighting relay through CKT 1655 (DK GRN). The coil is energized and the switch contacts close providing battery positive voltage (B+) to the backup lights and cornering lights.
