  1. CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the G114 navigation receiver assembly connector.

    2. Disconnect the P2 rear television camera assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G114-11 (CA+) - P2-6 (CB+) Always Below 1 Ω
      G114-12 (V+) - P2-3 (CV+) Always Below 1 Ω
      G114-23 (CGND) - P2-5 (CGND) Always Below 1 Ω
      G114-24 (V-) - P2-2 (CV-) Always Below 1 Ω
      G114-11 (CA+) or P2-6 (CB+) - Body ground Always 10 kΩ or higher
      G114-12 (V+) or P2-3 (CV+) - Body ground Always 10 kΩ or higher
      G114-23 (CGND) or P2-5 (CGND) - Body ground Always 10 kΩ or higher
      G114-24 (V-) or P2-2 (CV-) - Body ground Always 10 kΩ or higher
