Rear courtesy/ reading lamps
Each rear quarter of the passenger compartment is fitted with combined lighting units comprising; a rear courtesy lamp and
reading lamp. The courtesy lamps operate automatically whenever a rear door is opened; the reading lamps function when
the integral switches are operated by occupants of the vehicle.
Trunk lamps
The trunk trim panel is fitted with lamps which operate auto matically whenever the trunk lid is opened; the switch is
incorporated within the latch mechanism.
Vanity mirror lamps
The vanity mirror lamps, two on each sun visor, operate auto matically when the mirror flap is opened, provided the sun
visor spindle is engage d in the stowage clip.
Operation
The BPM provides an enable signal for the glovebox, vanity mirror, trunk lid and map lamps. Actuation of the relevant
switch provides an earth path to the lamp.
The rear passenger reading lamps receive a supply di rect from fuse F10 in the RH heelboard fuse-box.
The front and rear courtesy lamps have separa te fade functions controlled by the BPM.
The door hazard / puddle lamps are controll ed locally by the relevant Door Module.
Fault analysis must be undertaken using the PDU, refer to Diagnosis and Testing.
Refer to the relevant Electrical Guid e for details of circuit operation.

Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The complexity of the electronics involved with the various Electronic Control Modules and the multiplexed communication
networks, preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the PDU
User Guide for detailed inst ructions on testing the interior lamps and circuits.
The PDU systematically tests and analyses the lamp assemblies, the bulbs and the electrical connections to them. It should
be noted that the lamps are not wired directly to the switches.
The lamps are controlled directly by the Bo dy Processor (it has a sufficient number of high power output stages to drive the
lamps / relays compared to other module s) except for the door guard / puddle lamps and the rear passenger reading lamps.

The Body Processor Module receives messages on the SCP network from the door modules relating to door ajar / closed /
locked status, sensed by the door courtesy switch(es).
Where a fault involving a lamp is indicated by the PDU, be fore replacing suspect components, some basic diagnostic
methods may be necessary to confirm that connecti ons are good and that wiring is not damaged.
