The In
strument Cluster is the primary electronic control module for the speedomete
r, tachometer, coolant temperature, fuel
level, driver information (Message Centre) and warning lamps.
The Instrument Cluster also:
- provides input / output informatio n signals for use by other modules.
- acts as a protocol converter (software language translator - the languages used on each network are very similar, but
neither can be directly interp reted by the opposite system) for communication between all modules on both the CAN and
SCP multiplexed networks. The Instrument Cluster is the only module on the vehicle which communicates between the two
networks.

Description and Operation
A multi-function switch located on the left stalk of the steering column switch assembly permits selection of either parking
(side), headlamps, auto-headlamp or off. Selection of a particular mode provides the appropriate input to the body
processor module (BPM).
Where the auto headlamp function is incorporated, a light sensor in the interior rear view mirror monitors ambient light and
provides an input to the BPM. The BPM responds by switching the low beam headlamps on or off as appropriate for the
prevailing light conditions.
The front and rear fog lamp switch is located on the fascia outboard of the steering column.
Front Lamps

Headlamp assembly
Each headlamp assembly consists of tw o headlamp units. The dipped beam lamp unit is located outboard and the main
beam lamp unit located inboard also carries the front parking (side) lamp. Access for bulb replacement is from the engine
compartment.

2—Headlamp (main beam)
3—Front Parking (side) Lamp
4—Front Direction Indicator
5—Front Side Marker
6—Side Repeater Lamp
7—Fog Lamp

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.

The BPM electronically controls many vehicle functions. It responds when a switch is actuated by providing output signals to
the appropriate devices, either di rectly or indirectly via relays. In addition the BPM establishes an ISO network link with the
Security and Locking Control Module (SLC M) and utilizes the SCP network to exchange data between the body system
modules.
The following tables are publis hed for guidance purposes and only provide a rough indication of the correlation between
circuit inputs and outputs; due to the complexity and necess ary functional interaction required for the vehicle there are
many circuits where inpu ts and outputs overlap.
Malfunction of modules must always be analyzed using the PDU as recommended in Diagnosis and Testing.
Inputs/outputs
• NOTE: The reverse lights and rear fog lights are NOT controlled by the BPM; refer to Security and Locking Control Module.
