Vehicle Signals
A comparison check can be made of each actual vehicle signal and
the signals recognized by the NAVI control unit.
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 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
Diagnosis results of self-diagnosis depend on if any error occurred during the time after selecting “Self Diag-
nosis” 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 malfunc-
tion, 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 per-
form 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.
Error item Possible cause Action to take
GPS Antenna Error GPS antenna connection malfunction
is detected. 1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, GO TO 3. If any error is not found, delete the error his-
tory and end the diagnosis. (This is not
a malfunction.)
3. Check if GPS antenna feeder line is snapped or pinched.
4. If the results from the above checkup show no malfunction, replace GPS
antenna, and then restart self-diagno-
sis.
5. If self-diagnosis results still show any malfunction, replace NAVI control unit.
FLASH-ROM Error Of Control Unit
NAVI control unit malfunction is
detected. 1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, replace NAVI con- trol unit. Refer to AV-155, "
Removal
and Installation of NAVI Control Unit" .
If any error is not found, delete the error
history and end the diagnosis. (This is
not a malfunction.)
Connection Of Gyro
GPS Communication Error GPS malfunction is detected. If the symptoms such as the GPS receipt
malfunction occur, intermittent malfunc-
tion caused by strong radio interference
may be detected.
If the malfunction always occurs, replace
NAVI control unit.
GPS ROM Error
GPS RAM Error
GPS RTC Error
DVD-ROM Mechanism not Detected

Malfunction is detected on DVD-
ROM drive pickup lens in NAVI con-
trol unit.

There is dirt and damage on the
DVD-ROM. 1. Check if the inserted DVD-ROM is
specified for this navigation system,
and the DVD-ROM is dirty, scratched or
warped.
2. If the results from the above checkup show no malfunction, insert the same
DVD-ROM, and then restart self-diag-
nosis.
3. If self-diagnosis results still show any malfunction, replace NAVI control unit.

A/C and AV Switch Self-Diagnosis FunctionNKS003KJ
Performing self-diagnosis makes it possible to check operation of A/C and AV switch indicator (LED) and other
switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “1” and “6” simultaneously for 3 seconds.
DIAGNOSIS FUNCTION
The following are checked:

All the indicators (LED) in the A/C and AV switch.

Continuity of the switches by sounding the buzzer when the A/C and AV switch and audio steering wheel
switch is pressed.

Continuity of harness between A/C and AV switch and audio steering wheel switch.
NOTE:
Rear window defogger switch operation is not checked (No beep sound even under normal status).
EXITING THE SELF-DIAGNOSIS MODE
