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 switch
is pressed.

Continuity of harness between A/C and AV switch and audio steering switch.

NOTE:

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.

width guiding lines may move horizontally. It is normal.

5.

Touch “X UP”, “X DOWN”, “Y UP”, and “Y DOWN” so as to align
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”.

NOTE:
If the setting value is changed on “SELECT GUIDELINE PAT-
TERN” and “ADJ GUIDELINE POSITION”, the change is not
