CAUTION / NOTICE / HINT

Note:

  • When "System initializing" is displayed on the multi-display assembly after disconnecting and reconnecting the cable to the negative (-) auxiliary 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).

Tip:

Images may be unclear even in normal conditions if:


  • Electrical devices are used in the cabin (noise may occur in the image).

  • Accessories that generate radio waves have been installed (noise may occur in the image).

  • The outer mirror switch assembly is operated (noise may occur in the image).

  • The multi-display is cold (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 rear television camera assembly lens is scratched.

  • The rear television camera assembly lens has drops of water on it or the humidity is high.

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

    CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the H97 multi-media module receiver assembly connector.

    2. Disconnect the U6 rear television camera assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      H97-39 (CA+) - U6-6 (CB+) Always Below 1 Ω
      H97-18 (V+) - U6-3 (CV+) Always Below 1 Ω
      H97-19 (V-) - U6-2 (CV-) Always Below 1 Ω
      H97-40 (CGND) - U6-5 (CGND) Always Below 1 Ω
      H97-39 (CA+) - Body ground Always 10 kΩ or higher
      H97-18 (V+) - Body ground Always 10 kΩ or higher
      H97-19 (V-) - Body ground Always 10 kΩ or higher
      H97-40 (CGND) - Body ground Always 10 kΩ or higher

    INSPECT MULTI-MEDIA MODULE RECEIVER ASSEMBLY (CA+, CGND)


    1. A0008PEE02

      Reconnect the H97 multi-media module receiver assembly connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      H97-39 (CA+) - H97-40 (CGND) Power switch on (ACC) 5.5 to 7.05 V
      H97-40 (CGND) - Body ground Always Below 1 V

    INSPECT MULTI-MEDIA MODULE RECEIVER ASSEMBLY (V+, GND1)


    1. Reconnect the U6 rear television camera assembly connector.

    2. A0007XVE12
      A0007XVE13
      A0005YHE02

      Using an oscilloscope, check the waveform of the rear television camera assembly.

      Component with harness connected

      (Multi-media Module Receiver Assembly)
      Tip:

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the multi-media module receiver assembly with the connector connected.

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Measurement terminal H97-18 (V+) - H97-12 (GND1)
      Measurement setting 200 mV/DIV., 50 μs./DIV.
      Condition Power switch on (IG), shift receiver in R
      Tip:

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

      • The video waveform is constantly output when the power switch is on (ACC).
