Headlamps

Battery positive voltage (B+) is supplied at all times to the headlamp switch and the lamp control module (LCM) through the LH MaxiFuse� Block LCM/HDLP circuit breaker via CKT 242 (RED). When the headlamp switch is placed in the ON position, battery positive voltage (B+) is supplied via CKT 10 (YEL) to the headlamp dimmer switch. and RH low beam headlamps via CKT 12 (TAN). When the headlamp dimmer switch is in the HIGH position, battery positive voltage (B+) is supplied to the LH and RH high beam headlamps via CKT 11 (LT ORN). When the ignition switch is in the RUN position and the ambient light sensor indicates darkness, the LCM provides battery positive voltage (B+) via CKT 10 (YEL) through the headlamp dimmer switch to the headlamps. When equipped with lamp monitoring, the headlamp battery positive voltage (B+) feeds pass through the adaptive lamp monitor control module to the headlamps. The low beam headlamps receive battery positive voltage (B+) through CKT 1312 (TAN or TAN/WHT). The high beam headlamps receive battery positive voltage (B+) through CKT 1311 (LT ORN or LT GRN/BLK).
