  2. CHECK HARNESS AND CONNECTOR (TELEVISION CAMERA ECU - TELEVISION CAMERA ASSEMBLY)


    1. A0161XTE01

      Disconnect the J92 connector from the television camera ECU.

    2. A0161KZE01

      Disconnect the Q43 connector from the television camera assembly.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J92-40 (CB+) - Q43-4 (CB+) Always Below 1 Ω
      J92-39 (CGND) - Q43-3 (CGND) Always Below 1 Ω
      J92-20 (CV+) - Q43-2 (CV+) Always Below 1 Ω
      J92-19 (CV-) - Q43-1 (CV-) Always Below 1 Ω
      J92-40 (CB+) - Body ground Always 10 kΩ or higher
      J92-39 (CGND) - Body ground Always 10 kΩ or higher
      J92-20 (CV+) - Body ground Always 10 kΩ or higher
      J92-19 (CV-) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT TELEVISION CAMERA ECU


    1. A0161KZE02

      Reconnect the J92 connector to the television camera ECU.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      Q43-4 (CB+) - Q43-3 (CGND) Engine switch on (IG), shift lever in R 5.5 to 6.5 V

  4. INSPECT TELEVISION CAMERA ASSEMBLY


    1. Reconnect the Q43 connector to the television camera assembly.

      A0160W9E01
    2. A0161YIE01

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

      Item Content
      Measurement terminal Q43-2 (CV+) - Q43-1 (CV-)
      Measurement setting 0.2 V/DIV., 50 μsec./DIV.
      Condition Engine switch on (IG), shift lever in R
      OK
      Pulses are as shown in the illustration.

      Tech Tips


      • For waveform 1, the cycle is approximately 63.6 μsec and the waveform is almost entirely longitudinal.

      • For waveform 2, the cycle is approximately 63.6 μsec and the waveform is almost flat.
