Images from All Cameras are Abnormal

PARK ASSIST / MONITORING: REAR VIEW MONITOR SYSTEM (w/ Side Monitor System): Images from All Cameras are Abnormal
- Images from All Cameras are Abnormal

DESCRIPTION

The parking assist ECU displays images for the rear view monitor and side monitor screens. Each image signal is sent from the parking assist ECU to the multi-display assembly through the digital communication cable.

INSPECTION PROCEDURE

HINT
Images are difficult to discern even in normal conditions if:

* Noise may occur in the image during power back door operation. (w/ power back door system)
* Noise may occur in the image depending on electrical devices used in the cabin.
* Noise may occur in the image if accessories that generate radio waves have been installed.
* The camera screen is frosted over (the image immediately after turning the power switch on (IG) may be blurred or darker than normal).
* The camera lens is dirty with snow, mud, etc.
* A strong beam of light, such as a sunbeam or headlight, hits the camera.
* It is too dark around the camera (at night etc.).
* The ambient temperature around the camera is either too high or too low.
* The vehicle is tilted at a steep angle.
* The ambience of the camera is too bright. (When a strong light, such as a sunbeam reflected off the vehicle body, hits the camera, the image may be blurred. This is called the "SMEAR" phenomenon, peculiar to the CCD camera.)

PROCEDURE

1. CONFIRM SYMPTOMS

(a) Check if the same symptom occurs on the rear view monitor and side monitor screens.

Result:





HINT
* Conditions for displaying the rear view monitor screen (Shift lever in R)
* Refer to the conditions for displaying the side monitor screen Side Monitor System (w/ Side Monitor System (w/ Rear View Monitor System))
* The parking assist ECU displays images for the rear view monitor and side monitor screens.
* Each image signal is sent from the parking assist ECU to the multi-display assembly through the digital communication cable.
* If the same symptoms occur on the rear view monitor and side monitor screens, image signals between the parking assist ECU and multi-display assembly may be abnormal.

OK -- Continue to next step.

3. CHECK DIGITAL COMMUNICATION CABLE CONNECTOR

(a) Check the digital communication cable connector.

(1) Check the digital communication cable connectors between the parking assist ECU and multi-display assembly for any connection problems Electronic Circuit Inspection Procedure.

(b) Check if the same malfunction recurs when the rear view monitor and side monitor screens are displayed.

OK:

Screen display is normal.

Result:





B -- REPLACE WIRE HARNESS (DIGITAL COMMUNICATION CABLE)

A -- END

4. REPLACE WIRE HARNESS (DIGITAL COMMUNICATION CABLE)

(a) Replace the digital communication cable between the parking assist ECU and multi-display assembly with a new one.

(b) Check if the same malfunction recurs when the rear view monitor and side monitor screens are displayed.

Result:





B -- REPLACE MULTI-DISPLAY ASSEMBLY

A -- END

5. REPLACE MULTI-DISPLAY ASSEMBLY

(a) Replace the multi-display assembly with a new or normally functioning one Removal.

(b) Check if the same malfunction recurs when the rear view monitor and side monitor screens are displayed.
