DESCRIPTION

The display signal from the rear television camera assembly is transmitted to the navigation receiver assembly via the parking assist ECU.

WIRING DIAGRAM





INSPECTION PROCEDURE

NOTICE:
* When "System initializing" message is displayed on the navigation receiver assembly after the battery terminal disconnected, correct the steering angle neutral point Initialization.
* Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the advanced parking guidance system may be needed Calibration.

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

* Noise may occur in the image depending on electrical devices used in the cabin.
* Noise may occur in the image if the outer mirror switch assembly is operated.
* 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.)
