Diagnosis and Testing

General Equipment

Inspection and Verification

NOTE: If a new navigation system display module is installed, allow the data from the
navigation CD ROM to download (approximately 10 minutes) to the navigation system
display module before inputting a destination into the navigation system display module.
The vehicle must then be driven until the navigation system is fully calibrated. Route
guidance will commence at approximately 30% of the calibration process and at 100% of
calibration the route guidance will be accurate.

1. 1. Verify the customer concern.

2. 2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection Chart

3. 3. If an obvious cause for an observed or reported concern is found, correct the cause

(if possible) before proceeding to the next step.

4. 4. If the cause is not visually evident, refer to the Self-Diagnostic Mode.

Self-Diagnostic Mode

NOTE: It is necessary to carry out part of the system diagnosis outside of the workshop.
Make sure there that are no large buildings/obstructions or metal objects in the
immediate vicinity.
NOTE: Make sure the navigation CD ROM is installed in the navigation system display
module before entering the Self-Diagnostic Mode.
NOTE: The navigation system display module will stay activated for up to ten minutes
after the unit has been switched OFF.

Switch the navigation system display module ON.

The navigation system constantly monitors it's inputs and outputs. If a concern is detected,
a diagnostic trouble code (DTC) will be stored in the navigation system memory.
