DESCRIPTION
The display signal from the rear television camera assembly is transmitted to the multi-display assembly via the parking assist ECU.
WIRING DIAGRAM
for only for models with the vehicle identification number on the certification label ending with the character A and w/o Seat Memory
except only for models with the vehicle identification number on the certification label ending with the character A and w/o Seat Memory
CAUTION / NOTICE / HINT
Note
When "!" mark is displayed on the parking assist ECU after the auxiliary battery terminal has been disconnected, correct the steering angle neutral point.
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 panoramic view monitor system may be needed.
Tech Tips
Images may be unclear even in normal conditions if:
Electrical devices are used in the cabin (noise may occur in the image).
The camera lens 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 television camera assembly lens is scratched.
The 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.
PROCEDURE
CHECK PANORAMIC VIEW MONITOR SYSTEM
Check if the same malfunction occurs when the panoramic view monitor screen is displayed.
