INSPECTION PROCEDURE

Note:

  • When "System initializing" is displayed on the accessory meter assembly after disconnecting the cable from 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:


  • 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.

  • 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 - LUGGAGE ELECTRICAL KEY SWITCH)


    1. Disconnect the L164 multi-media module receiver assembly connector.

    2. Disconnect the S101 luggage electrical key switch connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      L164-19 (V-) - S101-2 (CV-) Always Below 1 Ω
      L164-18 (V+) - S101-7 (CV+) Always Below 1 Ω
      L164-40 (CGND) - S101-1 (CGND) Always Below 1 Ω
      L164-39 (CA+) - S101-6 (CB+) Always Below 1 Ω
      L164-19 (V-) or S101-2 (CV-) - Body ground Always 10 kΩ or higher
      L164-18 (V+) or S101-7 (CV+) - Body ground Always 10 kΩ or higher
      L164-40 (CGND) or S101-1 (CGND) - Body ground Always 10 kΩ or higher
      L164-39 (CA+) or S101-6 (CB+) - Body ground Always 10 kΩ or higher

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


    1. A01H13JE61

      Remove the multi-media module receiver assembly with the connector still connected.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      L164-40 (CGND) - Body ground Always Below 1 Ω

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      L164-39 (CA+) - L164-40 (CGND) Power switch on (ACC) 5.5 to 7.05 V

      *e Video Waveform - -

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

      Tip:

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

      Item Content
      Terminal No. (Symbol) L164-18 (V+) - L164-40 (CGND)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition

      Waveform 1: Power switch on (READY), shift lever in R, camera lens is not covered, displaying an image

      Waveform 2: Power switch on (READY), shift lever in R, camera lens is covered, blacking out the screen
      Tip:

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

      OK
      Waveform is as shown in the illustration.
