Radio, Stereo, and Compact Disc: Testing and Inspection

The complexity of the electronics involved with the audio system preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the PDU User Guide for detailed instructions on testing the audio system.

The PDU systematically tests and analyses all functions of the audio system.

Where a fault involving the audio system is indicated by the PDU, some basic diagnostic methods may be necessary to confirm that connections are good and that the wiring is not damaged, before installing new components.

For further information regarding trouble codes for this system, please refer to Body Control Module, Testing and Inspection Procedures.
