DIAGNOSIS BY HISTORY OF ERRORS
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-diag-
nosis” is completed, the diagnosis result will be judged normal. Therefore, those errors in the past, which can-
not be found by the “Self-diagnosis”, must be found by diagnosing the “History of Errors”.
The History of Errors 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 max 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 History of
Errors), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the History of Errors
to find the items which show an increased number of occurrences, and diagnose the item.

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 auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving with
tire chain fitted on tires.
