Vehicle Width and Distance Guiding Line Correction
NKS002QV
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.

with a correction line created, and then adjust the guiding lines.
6.
If the guiding lines align with the correction lines, touch “SAVE”
so as to fix the lines, and then end the correction by touching
“END”. GO TO 7 if the guiding lines do not align with the correc-
tion lines.
7.
Touch “SELECT GUIDELINE PATTERN” on SELECT WORK
ITEM screen.
8.
Change the pattern of the guiding lines by touching “UP” or
“DOWN”. [Select from among 2 patterns (“PATTERN NO. 0 or
1”) of the guiding lines.]
9.
Fix the pattern of the guiding lines by touching “SAVE”.
10. End the correction by touching “END”.
