  2. CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - OUTER REAR VIEW MIRROR ASSEMBLY RH)


    1. Disconnect the F8 and F9 parking assist ECU connectors.

    2. Disconnect the I3 outer rear view mirror assembly RH connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F8-30 (RCB+) - I3-5 (SCB+) Always Below 1 Ω
      F8-28 (RCV+) - I3-6 (SCV+) Always Below 1 Ω
      F8-27 (RCV-) - I3-14 (SCV-) Always Below 1 Ω
      F8-29 (RGND) - I3-13 (SGND) Always Below 1 Ω
      F9-3 (GND1) - Body ground Always Below 1 Ω
      F8-30 (RCB+) or I3-5 (SCB+) - Body ground Always 10 kΩ or higher
      F8-28 (RCV+) or I3-6 (SCV+) - Body ground Always 10 kΩ or higher
      F8-27 (RCV-) or I3-14 (SCV-) - Body ground Always 10 kΩ or higher

      *a

      Component with harness connected

      (Parking Assist ECU)

      		 *b Waveform 1
      *c Waveform 2 *d Synchronization Signal
      *e Video Waveform - -

    2. Measure the waveform of the side television camera assembly RH using an oscilloscope.

      Tech Tips


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

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

      Measurement Condition
      Item Content
      Tester Connection F8-28 (RCV+) - F8-29 (RGND)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition

      • Waveform 1: Engine switch on (IG), steering pad switch assembly (panoramic view monitor main switch) on, camera lens not covered, displaying image

      • Waveform 2: Engine switch on (IG), steering pad switch assembly (panoramic view monitor main switch) on, camera lens covered, blacking out screen
      OK
      Waveform is as shown in illustration.
