    CHECK HARNESS AND CONNECTOR (REAR TELEVISION CAMERA ASSEMBLY - RADIO RECEIVER ASSEMBLY)


    1. Disconnect the U22 rear television camera assembly connector.

    2. Disconnect the H182 radio receiver assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      U22-6 (CB+) - H182-11 (CA+) Always Below 1 Ω
      U22-3 (CV+) - H182-12 (V+) Always Below 1 Ω
      U22-2 (CV-) - H182-24 (V-) Always Below 1 Ω
      U22-5 (CGND) - H182-23 (CGND) Always Below 1 Ω
      U22-6 (CB+) - Body ground Always 10 kΩ or higher
      U22-3 (CV+) - Body ground Always 10 kΩ or higher
      U22-2 (CV-) - Body ground Always 10 kΩ or higher
      U22-5 (CGND) - Body ground Always 10 kΩ or higher

    INSPECT RADIO RECEIVER ASSEMBLY (CA+, CGND)


    1. Reconnect the H182 radio receiver assembly connector.

    2. A0009CEE02

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      H182-11 (CA+) - H182-23 (CGND) Power switch on (ACC) 5.5 to 7.05 V
      H182-23 (CGND) - Body ground Always Below 1 V

    INSPECT RADIO RECEIVER ASSEMBLY (V+, GND1)


    1. Reconnect the U22 rear television camera assembly connector.

    2. A0007XVE19
      A0005HZE17
      A0005AGE02

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

      *a

      Component with harness connected

      (Radio Receiver Assembly)
      Tip:

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

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Measurement terminal H182-12 (V+) - H179-7 (GND1)
      Measurement setting 200 mV/DIV., 50 μs./DIV.
      Condition Power switch on (IG), shift lever 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).
