Exterior Lighting
LAMPS/LIGHTING - EXTERIORLAMP SYSTEMS
Lighting circuits are protected by fuses or circuit breakers. Lighting circuits require an overload protected power source, ON/OFF device, lamps and body ground to operate properly. Plastic lamps require a wire in the harness to supply body ground to the lamp socket. If a socket has become corroded, clean socket and bulb base with abrasive fiber sanding pad or metallic bristle brush. Replace sockets and bulbs that are deformed from corrosion that could prevent continuous body ground.
Wire connectors can make intermittent contact or become corroded. Before coupling wire connectors, inspect the terminals inside the connector. Male terminals should not be bent or disengaged from the insulator. Female terminals should not be sprung open or disengaged from the insulator. Bent and sprung terminals can be repaired using needle nose pliers and pick tool. Corroded terminals appear chalky or green. Corroded terminals should be replaced to avoid recurrence of the problem symptoms.
Begin electrical system failure diagnosis by testing related fuses and circuit breakers in the fuse block and engine compartment. Verify that bulbs are in good condition and test continuity of the circuit ground. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pinout information and location views for the various wire harness connectors, splices and grounds.
Fig.1 Daytime Running Lamp Module Location:
DAYTIME RUNNING LAMP (CANADA ONLY)
JR vehicles built for use in Canada are equipped with a Daytime Running Lamp (DRL) system. The DRL system operates the high beam filaments at a lower intensity when the engine is operating and the exterior lamp switch is in either the OFF or parking lamp ON position and the parking brake is not applied. The DRL system is controlled by the Daytime Running Lamp Module located on the back of the junction block, behind the instrument panel. The DRL module overrides the headlamp switch when the headlamps are turned OFF The headlamps operate normally when the headlamps are turned ON. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

HEADLAMP TIME DELAY SYSTEM
The optional Headlamp Time Delay system is controlled by the Body Controller (BC) and a relay located in the junction block. The headlamp time delay system can be activated by turning ON the headlamps when the engine is running, turn OFF the ignition switch, then turn OFF the headlamp switch. The BC will allow the headlamps to remain ON for 90 seconds before they automatically turn off. Refer to the Owner's Manual for more information.
BRAKE LAMP SWITCH
The brake lamp switch is located under the instrument panel at the brake pedal arm (Fig 2). It controls operation of the vehicle's brake lamps. Also, if the vehicle is equipped with speed control, the brake lamp switch will deactivate speed control when the brake pedal is depressed.
When the brake pedal is depressed, the plunger on the outside of the switch extends outward. This action closes the electrical contacts within the switch, completing the circuit to the brake lamps at the rear of the vehicle, thus illuminating the brake lamps and the Center-High-Mounted Stop Lamp (CHMSL).
Fig.11 Combination Flasher Location:
COMBINATION FLASHER
The turn signal flasher and the hazard warning flasher are combined into one unit called a combination flasher (combo-flasher).
An inoperative or incomplete turn signal circuit will result in an increase in flasher speed.
The flasher is mounted to the back side of the multi-function switch.
Fig.19 Hazard Warning Switch:
HAZARD WARNING SWITCH
The hazard warning switch push button protrudes from the top of the steering column. The hazard warning switch push button is identified with a double triangle, which is the international control symbol for hazard warning.
The hazard warning system is actuated by a push button located on the top of the steering column between the steering wheel and the instrument panel. The hazard switch is identified with a double triangle on top of the button. Push and release the button to turn the hazard function ON or OFF. The button will move out from the steering column in the ON position and will remain in toward the column in the OFF position.
HEADLAMP SWITCH
Headlamp Dimmer Switch
The headlamp dimmer switch is incorporated into the turn signal switch. Proper procedures can be found in Turn Signal and Flashers. More information can be found in the Wiring Diagrams.
Headlamp Switch
Service procedures for the headlamp switch can be found in Instrument Panel and Gauges. More information can be found in the Wiring Diagrams.
Multi-Function/Exterior Lamp Switch:
MULTI-FUNCTION SWITCH
The multi-function switch (Fig. 32) contains:
- Turn signals
- Hazard warning
- Headlamps
- Headlamp beam select
- Parking lamps
- Panel dimmer
- Fog Lamp
- Headlamp optical horn
- Windshield wiper
- Pulse wipe
- Mist wipe
- Windshield washer switches.
The multi-function switch is mounted center of the steering column.There are two levers, one on each side of the steering column.
The left side controls the signaling and lighting. The right side controls the windshield wiper and washer system. When the driver wishes to signal his intentions to change direction of travel, he moves the left lever upward to cause the right signals to flash and downward to cause the left signals to flash. After completion of a turn the system is deactivated automatically. As the steering wheel returns to the straight ahead position the turn signals are canceled. A canceling cam is molded to the clock spring mechanism which comes in contact with the cancel actuator on the multi-function switch. The canceling cam lobe pushes on the cancel actuator and returns the switch to the OFF position.
If only momentary signaling such as indication of a lane change is desired, the switch is actuated to a left or right intermediate detent position. In this position the signal lamps flash as described above, but the switch returns to the OFF position as soon as the lever is released.
When the system is activated, one of two indicator lamps mounted in the instrument cluster flashes in unison with the turn signal lamps, indicating to the driver that the system is operating. The windshield wiper and wash system is covered in Wipers/Washers.

ILLUMINATED ENTRY
The Illuminated Entry System is available on vehicles equipped with the Remote Keyless Entry system. The Illuminated Entry System turns ON the courtesy lamps when the remote keyless entry system is activated. The Remote Keyless Entry Module and the Body Controller are used to control the system. Courtesy lamps will turn on for 30 seconds (± 1 second) and fade to OFF over a five second period.
The Illuminated Entry System also turns ON the courtesy lamps (and ignition switch lamp) when door is opened. The courtesy lamps will remain ON while the door is open, then fade to OFF 30 seconds (± 1 second) after the last door is closed.
The courtesy and ignition switch lamps will fade to OFF immediately when the ignition is switched to ON.
The Illuminated Entry System cannot be activated during the 30 second (± 1 second) period after the ignition switch is turned OFF. After a door is opened and closed during this 30 second period, the system will function as previously described.
When the battery voltage has been interrupted to the Illuminated Entry System, the system will not function until the remote keyless entry UNLOCK is actuated.
