| Diagnosis and Testing Special Tool(s) | | 73 Digital Multimeter 105-R0051 or equivalent | 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
| - Fuse(s)
- Wiring harness
- Loose or corroded connector(s)
- Global positioning System (GPS) antenna
- Audio/navigation unit
| - If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the concern is not visually evident, verify the symptom and refer to the Symptom Chart.
System Entry Procedure NOTE:It is necessary to carry out part of the system diagnosis outside (wheel speed 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 the 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 diagnostics. If error codes are retrieved, for additional information refer to the Error Code Index.

If the tires fitted to the vehicle are not in the TIRE SIZE screen, it will be necessary to input them using the main menu option of SYSTEM SETUP. - Select NEW TIRES or USED TIRES according to the tires fitted to the vehicle Use the side to side keys to select each number of the tire size required and press enter after each selection.
- If a new antenna is fitted, check for GPS reception in the DEALER CHECK and carry out a short test drive.
- If a new audio control unit is fitted carry out a language selection, DEALER CHECK and carry out a short test drive.
- If a new CD auto changer is fitted, check the unit for correct operation.
