Image from Camera for Advanced Parking Guidance is Abnormal
PARK ASSIST / MONITORING: ADVANCED PARKING GUIDANCE SYSTEM: Image from Camera for Advanced Parking Guidance is Abnormal
- Image from Camera for Advanced Parking Guidance is Abnormal
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 the "System initializing" message is displayed on the navigation computer sub-assembly after the auxiliary battery cable has been 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:
* Electrical devices are used in the cabin (noise may occur in the image).
* Accessories that generate radio waves have been installed (noise may occur in the image).
* The outer mirror switch assembly is operated (noise may occur in the image).
* 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 ambient light around 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.)
* The rear television camera assembly lens is scratched.
* The rear television camera assembly lens has drops of water on it or the humidity is high.
* When the camera is used under fluorescent lights, sodium lights, or mercury lights etc., the lights and the illuminated area may appear to flicker.
