SIDE CAMERA LH COMMUNICATION SIGNAL CIRCUIT

Description

INFOID:0000000006216358

• Around view monitor control unit supplies to the front camera, rear camera and side camera. And then it

superimpose the images from each camera and outputs then to the front display unit. 

• Superimpose the guiding lines, predictive course line and sonar indicator to the camera image that outputs

to the front display unit. 

• Around view monitor control unit performs the reception/transmission of communication signal with each

camera. 

Diagnosis Procedure

INFOID:0000000006216359

1.

CHECK CONTINUITY COMMUNICATION SIGNAL CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect around view monitor control unit connector and door mirror (driver side) connector.

3.

Check continuity between around view monitor control unit harness connector and door mirror (driver
side) harness connector.

4.

Check continuity between around view monitor control unit harness connector and ground.

Is inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK COMMUNICATION SIGNAL

1.

Connect around view monitor control unit connector and door mirror (driver side) connector.

2.

Turn ignition switch ON.

3.

Check signal between around view monitor control unit harness connector and ground.

Is inspection result normal?

YES

>> Replace around view monitor control unit. Refer to 

AV-233, "Removal and Installation"

.

NO

>> Replace side camera LH. Refer to
