Turn Signal Lamp: Description and Operation

TURN SIGNAL LAMPS

The TURN/HAZ fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM) for the turn signal lamps and hazard lamps. When the turn signal switch is place in either the TURN LEFT or TURN RIGHT position, ground is applied from G202 through the turn signal switch to the BCM the BCM then applies battery positive voltage to the front and rear turn signal lamps supply voltage circuits. The left front turn signal lamp is grounded at G101 and the right front at G100. The left rear turn lamp is grounded at G301 and the right rear at G302.
