Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The PDU is unable to diagnose radio head, CD autochanger or amplifier faults; there are no self-diagnostics associated with
these components.
PDU is able to test the speakers and the antenna, along with associated wiring and connections, therefore by a process of
elimination, the other components can be diagnosed.

Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The PDU tests whether or not the antenna raises and lowers correctly. Although it is obvious if the antenna is not operating,
the PDU analyses why it is not operating an d indicates problems such as a faulty radio head signal output, faulty wiring, loss of power due to a blown fuse.

Speakers - Speakers
Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
PDU can test for correct operation of each speaker and can provide fault guidance for any that fail to function.
PDU can indicate problems such as a faulty radio head output power signal, faulty power amplifier (where fitted), faulty
wiring, loss of power due to a blown fuse.

Front End Body Panels
A false bulkhead together with two insulation covers, are installed between the engine compartment and the BIW front
bulkhead to provide optimum insulation ag ainst noise and heat intrusion. Two plenum braces bolted between the BIW upper toeboards and the plenum further increase bodyshell structural integrity. The plastic ra diator grill and vane block achieve
weight reductions over steel parts and provid e high resistance to front end corrosion.
