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

      Standard Resistance
      Tester Connection Condition Specified Condition
      I177-11 (CA+) - T6-6 (CB+) Always Below 1 Ω
      I177-12 (V+) - T6-3 (CV+) Always Below 1 Ω
      I177-24 (V-) - T6-2 (CV-) Always Below 1 Ω
      I177-23 (CGND) - T6-5 (CGND) Always Below 1 Ω
      I177-11 (CA+) - Body ground Always 10 kΩ or higher
      I177-12 (V+) - Body ground Always 10 kΩ or higher
      I177-24 (V-) - Body ground Always 10 kΩ or higher
      I177-23 (CGND) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT NAVIGATION RECEIVER ASSEMBLY


    1. Reconnect the I177 navigation receiver assembly connector.

    2. A01I10OE23

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      I177-23 (CGND) - Body ground Always Below 1 Ω

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      I177-11 (CA+) - I177-23 (CGND) Ignition switch ACC 5.5 to 7.05 V

      *a Waveform 1 (camera lens is not covered, displaying an image)
      *b Waveform 2 (camera lens is covered, blacking out the screen)
      *c Synchronization Signal
      *d Video Waveform

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

      Tech Tips

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

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Measurement terminal I177-12 (V+) - I6-7 (GND1)
      Measurement setting 200 mV/DIV., 50 μs./DIV.
      Condition Ignition switch ON, shift lever in R

      Tech Tips


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

      • The video waveform is constantly output when the ignition switch is turned to ACC.
