Sensor Check
The display screen provides visual checks that all input sensors are operating. The following sensor status is displayed:
SENSOR STATUS
| Wheel sensors | Wheel speed sensors used by the ABS\ASC\DSC system calculate the vehicle speed. When the vehicle is stationary the wheel speed sensor boxes will show zero. When the car is driven the values should increase in proportion to the vehicle speed. When the vehicle is driven in a straight line, the values should be similar. |
| GPS satellites | Displays the number of satellites visible to the system at that time. |
| GPS status | Displays the number of satellites visible and the GPS system status. The GPS statuses displayed are as follows:GPS Error: - There is a communication error between the GPS receiver and the navigation computer. Satellite Search: - The system is searching for satellites and may indicate a failure of the GPS system. Ensure that the GPS antenna is not covered and check harness connections between the GPS receiver and the antenna. Satellite Contact: - The system is tracking a number of satellites. This message shows that the system is functioning correctly, but there is not enough information to determine the vehicle position. Check that the GPS antenna is not covered in any way. It may take several minutes for the GPS system to locate enough satellites to determine the vehicle position. Position Known: - The system is tracking a number of satellites and has a current fix on the vehicle position. This shows that the system if functioning correctly. |
| Gyro | The navigation computer has a gyro which determines changes of vehicle direction. When the vehicle turns to the left, the direction icon should move anti-clockwise and the displayed value should decrease. When the vehicle turns to the right the direction icon should move clockwise and the displayed value should increase. The amount movement of the direction icon and of increase or decrease in the displayed value depends on the tightness of the turn. |
| Direction | The direction sensor determines whether the vehicle is travelling forward or backward. With the vehicle in any forward gear or neutral or 'park' for automatic transmission, the display will show 'Forward'. When reverse gear is engaged the display should show 'Backward'. |
Selecting FUNCTIONS will return to the pop-up menu or selecting < RETURN will return to the Service Mode menu.
Service Mode is exited by pressing the MENU button on the control panel which returns the system to the main navigation.
