INSPECTION PROCEDURE

  • NOTICE:
When "System initializing" is displayed on the parking assist ECU after the cable is disconnected from the negative (-) battery terminal, 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 side monitor system may be needed ().
  • HINT:
  • Images are difficult to discern even in normal conditions if:
Noise may occur in the image while adjusting or retracting the outer rear view mirror assembly.
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 engine 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, particular to the CCD camera.)
1.CHECK SYMPTOMS

Check if the same malfunction occurs when the parking assist monitor screen is displayed.
