Hazard Warning Lamps: Description and Operation

HAZARD 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 hazard switch is placed in to the ON position, the driver information center (DIC) sends a signal to the BCM through he hazard switch signal circuit. The BCM then flashes all of the turn signal lamps ON and OFF.
