SIDE MONITOR SYSTEM Image from Camera for Side Monitor is Abnormal

DESCRIPTION

The display signal from the side television camera assembly is transmitted to the multi-display assembly via the parking assist ECU.

INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the multi-display after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point Click here.

  • 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 Click here.

Tech Tips

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 (passenger side).

  • 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.)
