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 rear view 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 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 ignition switch ON 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.)

PROCEDURE


  1. CONFIRM SYMPTOMS


    1. Check if the same symptom occurs on the rear view monitor and side monitor screens.

      Tech Tips


      • Conditions for displaying the rear view monitor screen (Shift lever in R).

      • Refer to the conditions for displaying the side monitor screen (w/ Rear View Monitor System) Click here.

      • Refer to the conditions for displaying the wide view front monitor screen (w/ Side Monitor System) Click here

      • The parking assist ECU displays images for the rear view monitor and side monitor screens.

      • Each image signal is sent from the parking assist ECU to the accessory meter assembly through the digital communication cable.

      • If the same symptoms occur on the rear view monitor, wide view front monitor and side monitor screens, image signals between the parking assist ECU and accessory meter assembly may be abnormal.
