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-198, "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.

Vehicle Width and Distance Guiding Line Correction

NKS0023V

DESCRIPTION

CONSULT-II is used to modify the guiding lines of the width of vehicle and the distance from rear end of vehi-
cle on the rear view monitor when these lines are derated from the actual width and/or distance, because of
rear view camera replacement, etc.

VEHICLE WIDTH AND DISTANCE GUIDING LINE CORRECTION PROCEDURE

1.

Create a correction line to modify the guiding lines inside moni-
tors. Draw lines on the rearward area of the vehicle passing
through the following points: 200 mm (7.87 in) from both sides of
the vehicle, and 0.5 m (1.64 ft), 1 m (3.28 ft), 2 m (6.56 ft), and 3
m (9.84 ft) from the rear end of the bumper.

2.

Connect CONSULT-II and CONSULT-II CONVERTER, and then
touch “REARVIEW CAMERA” on “SELECT SYSTEM” screen.

WARNING:

Correct the guiding line with the engine stopped for safety.

3.

Shift selector lever to R position.
