VEHICLE SIGNALS
A comparison check can be made of each actual vehicle signal and
the signals recognized by the system.
SPEAKER TEST
When selecting “Speaker Test”, speaker diagnosis screen is dis-
played. When pressing “Start”, test tone emits from the speaker. At
that time, when pressing “Start”, test tone emits from next speaker.
Then, when pressing the “End”, test tone stops.
NOTE:
The frequency of test tone emitted from each speaker is as follows.

NAVIGATION
Steering Angle Adjustment
The steering angle output value detected with the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function 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” determine if any malfunction occurred between selecting “Self-diag-
nosis” and displaying “Self-diagnostic Results”.
If an error occurred before the ignition switch was turned ON and does not occur again until “Self-diagnosis” is
completed, the trouble diagnosis result will be 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 past. The frequency of occurrence is displayed by 2
types: the count down type and the count up type. Select either type according to the error item.
In “Error History” of models with NAVI, time and place that the selected error last occurred are displayed. Be
careful about the following.

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

Count Down Type

When the error is detected, set the counter to 40. If the system is normal when turning the ignition switch
ON, the counter decreases by 1.

The lower limit of the counter is 1. It can be reset to 0 by “Delete log” switch or CONSULT-II.
Count Up Type

When the ignition switch is turned ON if the error is detected, the counter increases 1. Even if it is normal
when the ignition switch is turned ON the next time, the counter does not decrease.

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 or CONSULT-II.
Error Item
Some error items may be displayed simultaneously according to the cause. If some error items are displayed
simultaneously, the detection of the cause can be performed by the combination of display items
