| Diagnosis and Testing Refer to Wiring Diagrams Section 415-00, for schematic and connector information. Worldwide Diagnostic System (WDS) Principles of Operation NOTE:Voice control will only operate with the ignition in position II and the components required switched ON. Voice Control The portable support electronics (PSE) module has a voice control system. The customer will be able to push the MODE button on the audio control switch located on the steering column lower shroud, this will activate the PSE module and allow voice control. An audible noise will be heard through the audio unit speakers after which, a voice command can then be spoken into the microphone located on the A-pillar or cellular phone. The incoming calls and voice confirmation can be heard through the audio system speakers. When a voice command is spoken into the microphone or cellular phone, it will be sent as a signal to the PSE module. The signal is then sent from the PSE module to the relevant components on the medium-speed controller area network (CAN) bus network. The component will then convert the signal back into the original voice command. The components that the PSE module interacts with are as follows: - audio unit
- navigation system display module
- cellular phone
For additional information on the cellular phone system, REFER to the cellular phone Owner's Guide. Bluetooth An input can be given through the cellular phone with or without the cellular phone connected to the handset holder, providing that the cellular phone is supplied with the Bluetooth technology and that the cellular phone is programmed to the PSE module. The Bluetooth technology is a wireless system that interacts with the relevant component modules through the PSE module. The general operation of the Bluetooth is similar to the voice control. Bluetooth technology cannot transfer the cellular phone's PHONEBOOK to the audio unit or navigation system display module. If the cellular phone is placed into the handset holder the PHONEBOOK data will be transferred to the audio unit or navigation system display module. For additional information, REFER to the cellular phone Owner's Guide. Inspection and Verification NOTE: Make sure that the PSE module and cellular phone are configured to each other before starting a system diagnosis. ENTER the following PIN number on the cellular phone to configure the cellular phone to the PSE module: 0000. - Verify the customer concern by operating the system using the customers cellular phone.
- Visually inspect for obvious signs of electrical damage.
