| Diagnosis and Testing Inspection and Verification - Verify the customer concern by operating the system.
- Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection Chart | Mechanical | Electrical | - Damaged antenna
- Damaged CD ROM
| - Wiring harness
- Loose or corroded connector(s)
- Global positioning system (GPS) antenna
| - If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
System Entry Procedure NOTE:It is necessary to carry out part of the system diagnosis outside (wheel sensor test and GPS check). The only time it is necessary to the switch the ignition on, is to carry out the wheel sensor test. NOTE:Make sure the navigation CD-ROM is installed in the navigation module before carrying out the System Entry Procedure. The system diagnoses, tests and calibrates all functions of the navigation system and consists of a series of screens on the audio control unit which must be followed. - SWITCH the audio control unit OFF and PRESS the FM/AM, EJECT, ON and MN/RT buttons at the same time.
- Use UP and DOWN keys, to select the language required and press the enter key (center button).
- SELECT DEALER CHECK and PRESS the enter key. Follow the on-screen diagnostic. If error codes are retrieved, for additional information refer to the error code index.
