INSPECTION PROCEDURE

Note

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.

  • 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.

  • When the camera is used under fluorescent lights, sodium lights, or mercury lights etc., the lights and the illuminated area may appear to flicker.

  • When a strong light (such as when sunlight is reflected off a vehicle body) hits the camera, vertical streaks, a phenomenon particular to the camera, may appear in the image.

  • In order to position the camera, a portion of the vehicle appears in the side monitor image. This is not a malfunction.

  • Light from buildings or the taillights of vehicles may be reflected in the image when driving at night. This is not a malfunction.
