Hazard Warning System
A turn signal and hazard warning system is standard fadory-installed safety equipment. The turn signal and hazard warning system includes the following major components, which are described in further detail elsewhere in this service information:- Combination Flasher - The eledronic combination flasher is located on the back of the left multi- function switch, beneath the upper steering column shroud on the top of the steering column.
- Front Side Marker Lamps - The front side marker lamps are located on the outboard ends of the two front fender flares.
- Turn Signal Repeater Lamps - The turn signal repeater lamps are located on the outboard ends of the two front fender flares.
- Hazard Warning Switch - The hazard warning switch is integral to the left multi-function switch. The hazard warning switch button protrudes from an opening in the shroud on the top of the steering column.
- Turn Signal Cancel Cam - The turn signal cancel cam is integral to the steering column clock- spring, which is located beneath the shrouds on the top of the steering column.
- Turn Signal Indicators - The two turn signal indicators are integral to the Electro Mechanical 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 beside each headlamp on the front fender. The rear turn signal lamps are integral to the back-up/brake/rear turn signal/tail lamps located on either side of the rear of the quarter panels.
- Turn Signal Switch - The turn signal switch is integral to the left multi-function switch. The left multi-function switch control stalk actuates the turn signal switch in the steering column.
The turn signal system in this vehicle indudes a turn signal-on warning chime feature. The EMIC eledronic drcuitry monitors the turn signal indicators as well as eledronic vehide speed and distance messages received from the PCM over the PCI data bus network to provide this feature. If an indicator remains illuminated continuously with the vehide speed above about 25 kilometers per hour (15 miles per hour) for a distance of greater than about 1.6 kilometers (1 mile), the EMIC generates a chime through an integral chime tone generator (The distance is greater for export vehides).
Hard wired drcuitry conneds the turn signal and hazard warning system components to each other through the electrical system of the vehicle. Refer to the appropriate wiring information.
The turn signal system operates on battery voltage received on a 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 voltage so that the hazard warning remains operational regardless of the ignition switch position. When the turn signal switch control stalk is moved up or down, the turn signal system is activated. When the turn signal system is adivated, the circuitry of the turn signal switch and the combination flasher will cause the selected turn signal indicator, front park/turn signal lamp, front side marker lamp, repeater lamps, and rear tail/stop/turn signal lamp to flash on and off. 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, repeater lamps and rear tail/stop/turn signal lamps to flash on and off.
In order to provide the turn signal-on warning, the ElectroMechanical Instrument Cluster (EMIC) monitors vehicle speed and distance messages received from the PCM over the PCI data bus and the hard wired turn signal switch input to the duster electronic drcuit board. If a turn signal remains indicated for a distance of greater than about 1.6 kilometers (1 mile) and the vehide speed remains greater than about 24 kilometers-per-hour (15 miles- per-hour), the EMIC generates a repetitive chime at a slow rate to provide an audible reminder that a turn signal has been left on (distance is slightly longer with export vehicles). Once the warning chime begins to sound, it will continue until the turn signal is cancelled, until the vehicle speed falls below about 24 kilometers-per-hour (15 miles-per-hour), or until the ignition switch is turned to the Off position, whichever occurs first. This feature is not activated by a hazard warning input to the instrument cluster.
During both the turn signal and the hazard warning operation, if the exterior lamps are turned Off, the front park/turn signal lamps, repeater lamps and the front side marker lamps will flash in unison. If the exterior lamps are turned On, the front park/turn signal lamps, repeater lamps and the front side marker lamps will flash alternately.
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 at the end of this group. 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.
