Hazard Warning Lamps: Description and Operation

TURN SIGNAL & HAZARD WARNING SYSTEM
A turn signal and hazard warning system is standard factory-installed safety equipment on this model. The turn signal and hazard warning system includes the following major components, which are described in further detail:
- Combination Flasher - The electronic combination flasher is installed in a connector on a take out of the instrument panel wire harness. The combination flasher connector is located secured to a bracket located under the instrument panel on the outboard side of the steering column opening.
- Front Side Marker Lamps - The front side marker lamps are located on the two outboard ends of the grille opening panel, just ahead of the front fenders.
- Hazard Warning Switch - The hazard warning switch is integral to the left multi-function switch on the left side of the steering column. The hazard warning switch button protrudes from a dedicated opening in the shroud on the top of the steering column, just below the steering wheel.
- Turn Signal Cancel Cam - The turn signal cancel cam is integral to the clockspring, which is located beneath the shrouds on the top of the steering column, just below the steering wheel.
- Turn Signal Indicators - The two turn signal indicators, one right and one left, are integral to the ElectroMechanical Instrument Cluster (EMIC) located in the instrument panel.
- Turn Signal Lamps - The front turn signal lamps are integral to the front park/turn signal lamps located below each headlamp on the front of the grille opening panel. The rear turn signal lamps are integral to the back-up/brake/rear turn signal/tail lamps located on either side of the liftgate opening on the rear of the quarter panels.
- Turn Signal Switch - The turn signal switch is integral to the left multi-function switch on the left side of the steering column. The left multi-function switch control stalk that actuates the turn signal switch protrudes from a dedicated opening in the shroud on the left side of the steering column, just below the steering wheel.

Hard wired circuitry connects the turn signal and hazard warning system components to each other through the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the turn signal and hazard warning system components through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators.

The turn signal system operates on battery current received on a fused ignition switch output (run) circuit so that the turn signals will only operate with the ignition switch in the ON position. The hazard warning system operates on non-switched battery current received on a fused B(+) circuit so that the hazard warning remains operational regardless of the ignition switch position. When the turn signal (left multi-function) switch control stalk is moved up (right turn) or down (left turn), the turn signal system is activated. When the turn signal system is activated, the circuitry of the turn signal switch and the combination flasher will cause the selected (right or left) turn signal indicator, front park/turn signal lamp, front side marker lamp and rear tail/stop/turn signal lamp to flash ON and OFF. With the hazard warning switch in the ON position, the hazard warning system is activated. When the hazard warning system is activated, the circuitry of the hazard warning switch and the combination flasher will cause both the right side and the left side turn signal indicators, front park/turn signal lamps, front side marker lamps and rear tail/stop/turn signal lamps to flash ON and OFF.

During both the turn signal and the hazard warning operation, if the exterior lamps are turned OFF; the front park/turn signal lamps and the front side marker lamps will flash in unison. If the exterior lamps are turned ON, the front park/turn signal lamps and the front side marker lamps will flash alternately. Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the turn signal and hazard warning system.

WARNING: EYE PROTECTION SHOULD BE USED WHEN SERVICING GLASS COMPONENTS. PERSONAL INJURY CAN RESULT.

CAUTION:
- Do not touch the glass of halogen bulbs with fingers or other possibly oily surface, reduced bulb life will result.
- Do not use bulbs with higher candle power than indicated in the Bulb Application table. Damage to lamp and/or Daytime Running Lamp Module can result.
- Do not use fuses, circuit breakers, or relays having greater amperage values than indicated on the fuse panel or in the Owner's Manual.

NOTE: When it is necessary to remove components to service another, it should not be necessary to apply excessive force or bend a component to remove it. Before damaging a trim component, verify hidden fasteners or captured edges are not holding the component in place.
