Turn Signal Lamp: Description and Operation

TURN SIGNAL LAMPS

The STOP/TURN fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM) for the turn signal lamps. When the turn switch is placed in the left or right position, ground is applied to the BCM on the left or right turn signal switch signal circuit. The BCM then applies voltage to the appropriate front and rear supply voltage circuits.

Grounds for the various lamps are as follows:
- G100 supplies the right front lamps
- G101 supplies the left front lamps
- G400 supplies the right rear lamps
- G401 supplies the left rear lamps
