Perimeter Lighting

Perimeter Lighting provides a personal security feature by illuminating all exterior lights on the vehicle exterior for IS seconds when the keyless entry transmitter is used to unlock the doors and it is dark outside. The backup lamps, headlamps, park lamps and cornering lamps 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 and park lamps. Battery positive voltage, (B+) is supplied at all times through the IP Fuse Block PERIMETER LT Fuse 8Avia CKT 1654 (TAN) to the perimeter lighting relay. The RFA provides ground for the perimeter lighting relay via CKT 1655 (BK GRN). The coil is energized and the switch contacts close, providing battery positive voltage (B+) to the backup lamps and cornering lamps (if equipped).
