The exterior lighting system consists of the following lamps:

The turn signal/headlamp switch lever is located on the left side of the steering column. A twist-type knob on the end of the switch lever controls the operation of the parking lamps and headlamps. A solid tone will sound as a reminder if you open the drivers door with the key out of the ignition and the park lamps or the headlamps on. When either the parking lamps or headlamps are activated, the following lamps also illuminate:

Voltage is applied continuously to the tail relay pins 4 and 2. The coil is energized when the daytime running lamps control module is active in normal park or headlamp operation. When the coils are energized current flows through the tail fuse and then into the lamps mentioned above.

The instrument panel and instrument cluster assembly illumination lamps intensity is controlled by the IP lamp dimmer, instead of remaining at 100 percent.

Low Beam System Operation

The headlamps may be turned on two different ways. First, when the end of the of the turn signal/headlamp switch lever is turned to the second detent position, the headlamps will illuminate. A ground signal is provided to the DRL control module. The module then provides a ground path to the coils of the head relay and DRL relay. Since the head relay is provided with battery voltage to both the contacts and the coil, the coil becomes energized and closes the contacts providing voltage to the dimmer relay, through the DRL fuse to the DRL relay and through both head fuses (LH-LWR and RH-LWR) to both LH and RH low beam lamps. With voltage and ground provided to the coil of the DRL relay, the coil becomes energized and closes the contacts providing a direct path to ground for both headlamps through SP254 to G103. With voltage and ground provided, the low beam lamps light. Second, with the switch in the OFF position, for automatic lamp control (ALC). During ALC the headlamps will be in one of the following modes of operation:

High Beam System Operation

The high-beam headlamp operation is controlled using the turn signal/headlamp switch lever on the steering column. In order to change headlamp operation from low-beam to high-beam, push the switch lever toward the instrument panel (until the detent is felt) and release. With the switch lever in the high beam position, ground is provided to the DRL control module through the turn signal/headlamp switch and splice pack 250 to G203. With voltage applied at all times through the dome fuse to the DRL control module and ground is provided through SP261 and SP254 to G103, the DRL control module provides a ground to the coil of the dimmer relay. Since voltage is being applied to the dimmer relay coil, it becomes energized. Voltage is then applied through the closed contacts of the dimmer relay and the head fuses (LH-UPR) and (RH-UPR) to the high beam lamps in the headlamps. Since ground is provided to the headlamps through the closed contacts of the energized DRL relay and SP254 to G103, the high beam lamps light. The high-beam indicator (blue) in the instrument cluster will light during high-beam headlamp operation. In order to change headlamp operation back to low-beam operation, pull the turn signal switch lever toward the driver (until the detent is felt) and release.

Flash-to-Pass System Operation

The Flash-to-Pass feature allows the driver to signal the driver of another vehicle his intention to pass. This is achieved by pulling the lever toward the driver, which will cause the high beam operation to illuminate until the lever is released. The operation of the headlamps with the turn signal/headlamp switch in flash-to-pass mode is similar to the operation of the switch in the high beam mode, as mentioned in the previous paragraph, with the exception that 2 ground paths are provided to the DRL control module. One path is through junction block 1, the turn signal/headlamp switch and SP250 to G203, which simulates the operation of the light switch in the head position. The other is through the dimmer switch and SP250 to G203.

Refer to Headlamp Switch Replacement for turn signal/headlamp switch removal and installation procedures.

Daytime running lamps (DRL) are standard equipment on all models. With the ignition switch in START, voltage is applied to the DRL control module through the gauge fuse. Operating through the low beams at 80 percent intensity of the normal output, a number of conditions must be met before the daytime running lamps system will work properly:

When the above conditions are met, a path to ground is provided to the coil of the head relay. Voltage is applied through the closed contacts of the head relay, through the dimmer relay and the head fuses (LH-LWR and RH-LWR) to the low beam lamps in the headlamps. With no ground supplied to the coil of the DRL relay, the headlamps have no direct path to ground. A path to ground is then provided through the DRL control module which reduces the intensity of the headlamps to 80 percent.

The following will prevent DRL operation:

Mechanical System Operation

The front park/turn signal lamps are located next to the headlamp assembly. The turn signal/headlamp switch lever is located on the left side of the steering column. Turn the end of the switch lever to the first detent position in order to turn on the park lamps. When a turn is signaled, the appropriate front park lamp flashes to signal a turn. The turn signals operate only with the ignition switch in the ON or START positions and will not operate during hazard flasher operation. When making a partial turn, such as when changing lanes, the driver has the option of moving the lever to a detent stop. The turn signal lamps and the turn signal indicator will continue to flash as long as the lever is held in this position and will cancel automatically when the lever is released. The detent position allows a lane change or shallow turn to be made without failing to cancel the turn signal lamp. Moving the lever past the detent position to its furthest upward or downward position will provide conventional turn signal operation. Turn signal operation is controlled by the turn/hazard signal relay located in Junction Block #1 and the turn signal/headlamp switch lever. The park/turn signal lamp lens is clear over the park lamp and amber over the turn signal lamp. It contains one amber double filament bulb.

Circuit Operation

Voltage is applied from the turn fuse to cavity 7 of the hazard switch. Current flows through the switch to cavity 5 where it continues to cavity 2 of the turn/hazard flasher. Cavity 2 applies voltage to the timing coil. At the same time cavity 2 applies voltage to the contact that closes according to the timing of the turn/hazard flasher. When the contacts are closed it applies current to the turn signal/headlamp switch cavity 2. If no direction is set by the turn signal switch an open occurs between cavities 1,2 and 3 of the switch. Current flows only to the left or right set of lamps, depending which way the turn signal switch is turned to.

The following lamps are turned on pertaining to the side the switch is activated to:

Mechanical System Operation

The hazard switch is located above the heater control assembly and controls the operation of the hazard lamp circuit. Pressing the hazard switch to the ON position will cause the turn/hazard signal relay to disengage the turn signal circuit and engage the hazard lamp circuit. This causes both turn indicators in the instrument cluster assembly to flash on and off along with all exterior turn signal lamps. The hazard lamp circuit will operate regardless of the position of the ignition switch. Press the hazard switch a second time in order to turn the hazard lamps off. Turning the hazard switch off disengages the hazard lamp circuit and returns the turn/hazard signal relay to the turn signal mode.

Refer to Hazard Flasher Switch Replacement in Instrument Panel, Gages, and Console for hazard switch removal and installation procedures.

Circuit Operation

Voltage is applied from Hazard fuse to cavity 6 of the hazard switch. When turned to the on position current flows through the switch to cavity 5 where it continues to cavity 2 of the turn/hazard flasher. Cavity 2 applies voltage to the timing coil. At the same time cavity 2 applies voltage to the contact that closes according to the timing of the turn/hazard flasher. When the contacts are closed it applies current to the hazard switch cavity 4. Current flows from cavity 4 through the closed contacts at cavity 1 and 2.

The following lamps are turned on when cavities 1 and 2 are charged:

The tail lamps are located on the vehicle body at each side of the rear compartment lid. Each tail lamp consists of the following single filament bulbs:

The tail lamp lens is multi colored. A red lens covers the stop lamp and the side marker lamp, an amber lens covers the turn signal lamp and a clear lens covers the backup lamp.

Mechanical System Operation

Each of the tail lamps also contains a double filament stop lamp bulb. The stop lamp filament lights under the following conditions:

The high-mounted stop lamp contains 1 bulb and is located in the center of the rear seat back to window trim panel. The stop lamp is designed to operate in conjunction with the tail lamps whenever the brake pedal is depressed.

Circuit Operation

Voltage is applied continuously from the stop fuse to the stop lamp switch. Voltage is applied from the stop lamp switch to junction block 1 C6 cavity 6 when the brake pedal is pressed. Voltage flows to junction block 1 C5 cavity 7, continuing to SP450. At the same time that happens current flows through junction block 1 C3 cavity 1 to junction block 3 C3 cavity 2.

SP450 applies voltage to the following lamps:

Junction block 3 C3 cavity 2 applies voltage to the following brake signal receivers:

The backup lamps are designed to operate with the ignition in the ON position. Placing the transaxle in the R position closes the backup lamp circuit and turns the backup lamps on.

Manual Transaxle

On vehicles equipped with a manual transaxle, the circuit closes through the backup lamp switch. When the ignition switch is in the RUN or START positions it applies power to the gauge fuse, located in the junction block 2. Current flows from the fuse to the multifunction alarm module and out through the RED/BLU wire connected to C2 cavity 9. Continuing to junction block 3 C3 cavity 5, to junction block 3 C4 cavity 4, to SP258, finally going to the backup lamp switch cavity 2. When the switch is closed it allows voltage to be applied to junction block 1 C3 cavity 9 through backup lamp switch cavity 1, which leaves the junction block at C5 cavity 4. After leaving junction block 1 C5 cavity 4 current is split through SP450, to the rear combination lamp cavity 4. Ground is finally provided at the rear combination lamp cavity 5.

Automatic Transaxle

On vehicles equipped with an automatic transaxle, the circuit closes through the park neutral position (PNP) switch. When the ignition switch is in the RUN or START positions it applies power to the gauge fuse, located in the junction block 2. Current flows from the fuse to the multifunction alarm module and out through the RED/BLU wire connected to C2 cavity 9. Continuing to junction block 3 C3 cavity 5, to junction block 3 C4 cavity 4, to SP258, finally going to the park/neutral position switch cavity 4 (4 SPD A/T) or 6 (3 SPD A/T). When the switch is in the park position it closes and allows voltage to be applied to SP260 through park/neutral position switch cavity 5 (3 SPD A/T) or 8 (4 SPD A/T). SP260 applies voltage to the powertrain control module and also junction block 1 C3 cavity 9, which leaves the junction block at C5 cavity 4. After leaving junction block 1 C5 cavity 4 current is split through SP450, to the rear combination lamps cavity 4. Ground is finally provided at the rear combination lamp cavity 5.

There are two rear license plate lamps located in the rear bumper fascia directly over the license plate. Each rear license plate lamp contains one clear, single filament bulb. The rear license plate bulbs will light when either the parking lamps or headlamps are activated.
