Side Distance Guideline CorrectionINFOID:0000000003533545
This mode is used to modify the side distance guidelines if they are dislocated from the rear view monitor
image, because of variations of body/camera mounting conditions.
SIDE DISTANCE GUIDELINE CORRECTION PROCEDURE
1. Create a correction line to modify the screen.
Draw lines on the rearward of the vehicle passing through the
following points: 200 mm (7.87 inch) from both sides of the vehi-
cle, and
• *1: 0.5 m (1.5 feet)
• *2: 1 m (3 feet)
• *3: 2 m (7 feet)
• *4: 3 m (10 feet)
and from the rear end of the bumper
2. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn igni-
tion switch ON. Touch “REARVIEW CAMERA” on “SELECT
SYSTEM” screen.
CAUTION:
Stop engine for safety when correcting side distance guide-
line.

•After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.
•When measuring ECM signals with a circuit tester, never allow
the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
•Do not use ECM ground terminals when measuring input/out-
put voltage. Doing so may result in damage to the ECM's tran-
sistor. Use a ground other than ECM terminals, such as the
ground.
•B1 indicates the bank 1, B2 indicates the bank 2 as shown in
the figure.
