INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the accessory meter assembly after disconnecting the cable 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 parking assist monitor system may be needed Click here.

Tech Tips

Images may be unclear 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 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.

    2. Check the waveform of the television camera assembly using an oscilloscope.

      Item Content
      Terminal No. (Symbol) L146-18 (V+) - L146-40 (CGND)
      Tool Setting 0.2 V/DIV., 50 μs/DIV.
      Condition

      Waveform A: Engine started, shift lever in R (camera lens is not covered, displaying an image)

      Waveform B: Engine started, shift lever in R (camera lens is covered, blacking out the screen)

      Tech Tips

      The video waveform changes according to the image sent by the television camera assembly.

      OK
      Waveform is as shown in the illustration.
