Vehicle Signal
A comparison check can be made of each actual vehicle signal and
the signals recognized by the display control unit.
History of Error
Diagnosis results of self-diagnosis depend on if any error occurred
during the time after selecting “DCU Failure Diagnosis” until self-
diagnosis results is displayed.
Meanwhile, when an error occurs before selecting “DCU Failure
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 “History of
Error” for the past error that is not available with self-diagnosis.
“History of Error” stores error occurrences up to 50, and errors after
the 51st are displayed as the 50th.

Diagnosis by History of Error
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
“History of Error”). Check “History of Error” again after the malfunction was reproduced, and then perform
diagnosis focusing on the item of which number of time increased.

Vehicle Width and Distance Guiding Line CorrectionBKS00282
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: 250 mm (9.84 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.

“END”. GO TO 7 if the guiding lines do not align with the correc-
tion lines.
7. Touch “SELECT GUIDELINE PATTERN” on SELECT WORK
