1. Side marker
2. Turn signal indicator
3. Reverse lamp
4. Stop/Tail lamps
5. Reverse lamp bulb
6. Electrical connector
7. Turn signal indicator bulb

The tail lamp assembly is a one piece unit which contains a stop/tail lamp, a turn signal indicator and a reverse lamp.

The tail lamp assembly is located in a recess in the vehicle body. One stud on the outer edge of the lamp housing locates in a plastic clip on the vehicle body. The lamp is secured with two screws which are located on the inner edge of the lamp housing, near the tailgate aperture. In order to access the screws, removal of a small cover in the lamp housing is required.

Rear Stop/Tail Lamps

The upper lamp is a combined LED matrix for stop and tail lamp. The stop lamp is activated when the ignition is in ignition power mode 6 or above and the stop lamp switch is active (by depressing the brake pedal). The HMSL will also be activated when the brake pedal is pressed. The stop lamps can also be activated by the ABS when Hill Descent Control (HDC) is active (if fitted). The ABS module sends a High Speed CAN Powertrain bus CAN bus message to the CJB which supplies power to the stop lamps and HMSL.

The side lamps are operated by selecting side lamps or headlamps on the lighting control switch. The side lamps can be switched on at all times and are not dependent on power mode. The side lamps will also be illuminated when the lighting control switch is in the 'AUTO' position and a 'lights on' signal is received by the CJB from the rain/light sensor.

Turn Signal Indicator

The turn signal indicator is located next to the stop/tail lamp and uses a Silvervision 24W bulb.

The turn signal indicators are operated by the left steering column multifunction switch or by the hazard warning lamp switch. The left steering column multifunction switch is only active with the ignition in power mode 6, the hazard warning lamp switch is active at all times. When active, the turn signal indicators will flash at a frequency cycle of 400ms on 400ms off.

If a bulb fails, the remaining turn signal indicator bulb on that side of the vehicle flashes at normal speed. The applicable turn signal indicator in the Instrument Cluster (IC) will flash at double speed with the audible alert at twice the normal rate as well to alert the driver to the bulb failure.

Reverse Lamp

The reverse lamp is located adjacent to the turn signal indicator and uses a 16W bayonet fitting bulb.

The reverse lamp is active in power mode 6 and the CJB receives a reverse selected signal on the HS CAN bus. The automatic and manual transmissions have a reverse switch which senses when reverse is selected and sends the state out on the High Speed CAN Powertrain to the CJB.

Side Marker Lamp

The side marker lamp is located in the outer part of the tail lamp assembly, adjacent to rear fog lamp and uses LED.

The side marker lamp is active at all times when the side lamps are selected on using the lighting control switch. The side marker lamps will also be illuminated when the lighting control switch rotary switch is in the 'AUTO' position and a 'lights on' signal is received by the CJB from the light sensor.
