Speed Calibration

Usually the automatic distance correction function adjusts the devia-
tion in distance caused by the tires wearing down or the tire pressure
change. If prompt adjustment is necessary when the tire chains are
installed etc., perform this procedure.

ERROR HISTORY

The diagnostic results of “Self-diagnosis” indicate only malfunction detected during the current “Self-diagno-
sis”.
If an error occurred before the ignition switch was turned ON, and does not occur again until “Self-diagnosis” is
completed, the diagnosis result is judged normal. Therefore, errors in the past which cannot be found by “Self-
diagnosis”, must be found by checking the “Error record”.
The error history shows the error occurrence frequency in the past. The frequency of occurrence is displayed
by 2 types: the count down type and the count up type. The type is predetermined according to the error item.
In “Error History”, time and place that the selected error last occurred are displayed. Be careful about the fol-
lowing.

●

If there is a malfunction with the GPS antenna circuit board in the NAVI control unit, the correct date of
occurrence may not be displayed.

●

Place of the error occurrence is represented by the position of the current-location mark at the time an
error occurred. If current-location mark has deviated from the correct position, then the place of the error
occurrence cannot be located correctly.

Transition Screen

Count Up Type

●

At the time the ignition switch is turned ON if the error is detected, the counter increases by 1. If it is nor-
mal when the ignition switch is turned ON, the counter remains the same.

●

The upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log”
switch.
