Navigation System - Diagnostic Procedures
Issue:
This Technical Bulletin has been issued as information only to assist with the diagnosis of Navigation System concerns.
Action:
The following procedures will assist in diagnosing faults with the Navigation and Display System alone, troubleshooting from the symptom or logged Diagnostic Trouble Codes (DTCs). If a fault lies with the Audio, Telephone or Climate Control systems, diagnosis must be made using the diagnostic tools and information made available for those systems.
To retrieve any stored Navigation System DTCs; press and hold the Menu' and Telephone' hard keys simultaneously for 5 seconds, when the keypad screen appears release the hard keys, enter the code 917 and press the Enter' soft key, select the Self Check' soft key from the On Screen Diagnostics' menu and if any DTCs are stored, they will be displayed on screen.
The WDS unit can be used in multi meter mode to check wiring harness integrity.
TROUBLESHOOTING FROM SYMPTOM
