CAMERA CONT.
There are 2 functions: “Connection Confirmation”, “Adjust offset of rear view camera”.
Connection Confirmation
The input signals of steering angle sensor signal, reverse signal, and
vehicle speed signal can be checked.
Adjust Offset of Rear View Camera
If the adjustment of rear view monitor guiding line display position is
necessary when rear view camera is removed, use this mode to
adjust it.

1. CONSULT-II DIAGNOSIS
Perform CONSULT-II self-diagnosis and check the malfunction. Refer to AV- 2 4 3 , "
SELF-DIAG RESULTS" .
Is there a malfunction?
YES >> Refer to AV- 2 4 3 , "Display Item of Self-Diagnostic Results" .
NO >> GO TO 2.
2. REVERSE SIGNAL INSPECTION
1. Turn the ignition switch ON, and then select “Connection Confirmation” of “Camera Controller” on Confir-
mation/Adjustment mode.
2. Make sure that “Reverse Sensor” is turned ON when shifting the selector lever in R position.
Is it OK?
YES >> GO TO 3.
NO >> Check reverse signal circuit, and then repair the malfunctioning parts.
3. CHECK HARNESS BETWEEN CAMERA CONTROL UNIT AND REAR VIEW CAMERA
1. Turn ignition switch OFF.
2. Disconnect camera control unit connector and rear view camera connector.
3. Check continuity between camera control unit harness connec-
tor (A) B481 terminal 8 and rear view camera harness connector
(B) T109 terminal 1.
4. Check continuity between camera control unit harness connec-
tor (A) B481 terminal 8 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4. CHECK REAR VIEW CAMERA POWER SUPPLY
1. Connect camera control unit connector and rear view camera connector.
2. Turn ignition switch ON.
3. Shift the selector lever in R position.
4. Check voltage between camera control unit harness connector
B481 terminal 8 and ground.
OK or NG
OK >> GO TO 5.
NG >> Replace camera control unit.8 – 1 : Continuity should exist.
8 – Ground : Continuity should not exist.

REMOTE CONTROLLER
Rear view monitor image is not
clearFront glass of camera lens is dirtyDip a soft cloth into water and wipe the
glass softly.
There are raindrops, snow, etc. Wipe it with a soft cloth softly.
The sunlight or the headlight of following vehicle is
shining directly to the camera lens.It returns to the original condition if the light
applied to the lens disappears
The center position of possible
route line is not in the correct posi-
tion

Remove or replace the battery.

Replace steering angle sensor or camera control
unit.

Turn steering wheel when turning ignition switch
OFF.Perform the neutral position correction as
follows.

Fully turn the steering wheel to left/right.

Drive 100 m or more at vehicle speed 30
km/h or more. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The remote controller does not
respond.The remote controller is not pointing at the receiver. Point the remote controller at the receiver.
The battery in the remote controller is not set cor-
rectly.Set the battery correctly.
The battery in the remote controller is discharged. Replace the battery.
The transmitter of the remote controller or the
receiver is dirty.Clean the transmitter of the remote control-
ler and the receiver.

PRECAUTIONS
Revision: 2007 April2007 M35/M45

Before replacing ECM, perform ECM Terminals and Refer-
ence Value inspection and make sure ECM functions prop-
erly. Refer to EC-114, "
ECM Terminals and Reference Value"
.

Handle mass air flow sensor carefully to avoid damage.

Do not clean mass air flow sensor with any type of deter-
gent.

Do not disassemble electric throttle control actuator.

Even a slight leak in the air intake system can cause seri-
ous incidents.

Do not shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).

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/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.
