  1. REAR TELEVISION CAMERA ASSEMBLY


    1. B0065EGN17

      Disconnect the z22 rear television camera assembly connector.

    2. Measure the voltage on the wire harness side connector according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      z22-6 (CB+) - Body ground R - Body ground Power source Engine switch on (ACC) 5.8 to 6.5 V

      If the result is not as specified, there may be a malfunction on the wire harness side.

    3. Reconnect the z22 rear television camera assembly connector.

    4. Check for pulses between each terminal of the connector.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      z22-3 (CV+) - z22-2 (CV-) Y - BR Video signal

      Engine switch on (IG)

      Shift lever in R

      Camera lens not covered, displaying image

      Pulse generation

      (Refer to waveform 1)

      Engine switch on (IG)

      Shift lever in R

      Camera lens covered, blacking out screen

      Pulse generation

      (Refer to waveform 2)
      z22-5 (CGND) - Body ground GR - Body ground Camera ground Always Below 1 V
      Tip:

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

      If the result is not as specified, the rear television camera assembly may be malfunctioning.
