Direction indicator and side marker lamps
Each front direction indicator and side marker lamp is retained in the bumper cover by a lug at one end and a spring clip at
the other end. The side marker lamps are not electrically connected for certain markets.
The side repeater lamps are secured by sp ring clips on the lower edge of the lamp unit. In certain markets Jaguar leaper
badges are substituted for side repeater lamps.
Fog lamps
The fog lamps are located in recesses in the front bump er and secured by three screws. The la mps which are not
interchangeable left to right, are accessed from the rear of the bumper.
Operation
All lamps are controlled by the BPM which provides an appropriate output in response to an input received when a selected
switch is operated.
All lamps receive an input direct from th e BPM with the exception of the main be am, dip beam and front fog lamps which
receive an input from the BPM vi a the respective relays and fuses; refer to section 418-01.
Fault analysis must be undertaken using the PDU. Refer to Diagnosis and Testing.
Consult the relevant Electrical Guid e for details of circuit operation.
Rear Lamps

ItemPart NumberDescription
1—License Plate Lamps

License plate lamps
Each license plate bulb is accessible after removing the relevant lens. The license plate lamps can be accessed following
removal of the trunk lid liner and upper trim finisher.
Rear lamp assembly
Each rear lamp assembly incorporates a stop/tail lamp, a fog lamp, a reversing lamp and a direction indicator lamp. Access
for bulb replacement is from the trunk.
Side markers
Each side marker is retained in the bumper cover by a lug on one end of the unit and a spring clip at the other end. The unit is not electrically connected for all markets.
High mounted stop lamp
The high mounted stop lamp (HMSL) is secu red to studs on the center lower edge of the backlight and provides illumination
using five bulbs.
Operation
All lamps are controlled by the BPM which pr ovides an appropriate output in response to an input received when a selected
switch is operated.
The side marker lamps receive an input from the BPM via relay 3 and fuse F21. The license plate lamps receive an input
from the BPM via relay 3 and fuse F19. The rela y and fuses are located in the trunk fuse-box.
The tail lamps receive an input direct from the BPM.
The stop, reversing and rear fog lamps are controlled by the security and locking module (SLM) which receives inputs via
the SCP network from the BPM.
The HMSL is not controlled by the SLM; it receives input from the brake switch via relay 5 and fuse F8 in the trunk fuse-box.

The BPM and SLM monitor the stop lamps (n ot HMSL) and tail lamps for failure.
Fault analysis must be undertaken using the PDU, refer to Diagnosis and Testing.
Consult the relevant Electrical Guid e for details of circuit operation.
