Turn Signal Lamp: Description and Operation

TURN SIGNAL LAMPS

Ground is applied at all times from G201 to the turn signal switch in the multifunction switch. When the turn signal switch is placed in either the TURN RIGHT or TURN LEFT position, a ground signal is applied to the BCM through the either the right turn or left turn signal switch circuit. Battery positive voltage is applied at all times from the BATT MAIN 3 Fuse to the BCM. The BCM then applies a pulsating voltage to the front and rear turn signal lamps. The ground for the left front turn signal lamp is supplied from G101. The ground for the right front turn signal lamp is supplied from G102. The left rear turn signal lamp receives it ground from G301. The right rear turn signal lamp receives it ground from G302.
