Confirmation/Adjustment Mode

OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.




3. While pressing the "4" button, turn the volume control dial clockwise or counterclockwise for 30 clicks or more. (When the self-diagnosis mode is started, a short beep will be heard.)
- Shifting from current screen to previous screen is performed by pressing "BACK" button.




4. The initial trouble diagnosis screen will be shown, and items "Self Diagnosis (DCU)", "Self Diagnosis (NAVI)", "Confirmation/ Adjustment" and "CAN DIAG SUPPORT MONITOR" will become selective.
5. Select "Confirmation/Adjustment".




6. Each diagnosis is shown by selecting each screen switch on Confirmation/Adjustment screen.

DISPLAY DIAGNOSIS
Color tone and shading of the display control unit-generated image can be checked by the display of a color bar and a gray scale.






- If RGB signal is malfunctioning, the tint of the color bar display is as follows.

R (red) signal error: Light blue (Cyan) tint
G (green) signal error: Purple (Magenta) tint
B (blue) signal error: Yellow tint

VEHICLE SIGNALS




A comparison check can be made of each actual vehicle signal and the signals recognized by the display control unit.

NOTE: In case of confirming light signal, set the following D/N mode to ON/OFF of lighting switch (normal setting).

- OFF: D (Day mode)
- ON: N (Night mode)

Unless above setting, light signal (ON/OFF) may not be accurately displayed.

Navigation

Steering Angle Adjustment




The steering angle output value detected by the gyroscope can be adjusted.

Speed Calibration




Usually the automatic distance correction function adjusts the malfunction 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
Diagnosis results of self-diagnosis depend on if any error occurred during the time after selecting "Self Diagnosis" until self-diagnosis results is displayed.
Meanwhile, when an error occurs before selecting "Self Diagnosis", and if an error does not occur until self-diagnosis results is displayed, a diagnosis result is judged as normal.
Consequently, a diagnosis needs to be performed with "Error History" for the past error that is not available with self-diagnosis.
"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 vehicle mark at the time when the error occurred. If the vehicle mark has deviated from the correct position, then the place of the error occurrence may not be located correctly.
- 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.






Diagnosis by Error History
- When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunction, turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or delete "Error History"). Check "Error History" again after the malfunction was reproduced, and then perform diagnosis focusing on the item of which number of time increased.
- DVD-ROM error history may be restored because DVD-ROM cannot be temporarily read. (Driving on rough road etc.) Then, erase the error history. (This is not a malfunction.) Perform service in "Action to take" if error history are repeatedly indicated again.






Delete Unit Connection Log




Erase the connection history of unit and error history that is recorded in NAVI control unit (clear the connection history of the removed unit).
