ERROR HISTORY
DIAGNOSIS BY ERROR HISTORY
The "Self-diagnosis" results indicate whether an error occurred during the period from when the ignition switch is turned to ON until "Self-diagnosis" is completed.
If an error occurred before the ignition switch was turned to ON and does not occur again until the "Self-diagnosis" is completed, the diagnosis result will be judged normal. Therefore, those errors in the past which cannot be found by the "Self-diagnosis" must be found by diagnosing the "Error History".
The Error History displays the time and place of the most recent occurrence of that error. However, take note of the following points.
- Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the NAVI control unit has malfunctioned.
- Place of the error occurrence is represented by the position of the current-location mark at the time when the error occurred. If the current-location mark has deviated from the correct position, then the place of the error occurrence may be located correctly.
- The maximum number of occurrences which can be stored is 50. For the 51st and later occurrences, the displayed number remains 50.
When a reproducible malfunction occurred but its cause cannot be identified because several errors are present, record the item, number and place (longitude/latitude) of error occurrence (or delete the Error History), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the Error History to find the items which show an increased number of occurrences, and diagnose the item.
NAVIGATION
1. The navigation screen will be shown, and items "Display Longitude & Latitude", "Speed Calibration", "Angle Adjustment" and "Initialize Location" will become selective.
2. Select each switch on "NAVIGATION" screen to display the relevant diagnosis screen.
Angle adjustment
- Adjusts turning angle output detected by the gyroscope.
Speed Calibration
- During normal driving, distance error caused by tire wear and tire pressure change is automatically adjusted for by the automatic distance correction function. This function, on the other hand, is for immediate adjustment, in cases such as driving with tire chain fitted on tires.
