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.
