PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY)


    1. Disconnect the I35 navigation receiver assembly connector.

    2. Disconnect the I64 stereo component amplifier assembly connector.

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

      Standard Resistance
      Tester connection Condition Specified condition
      I35-2 (RL+) - I64-15 (II1+) Always Below 1 Ω
      I35-6 (RL-) - I64-14 (II1-) Always Below 1 Ω
      I35-2 (RL+) or I64-15 (II1+) - Body ground Always 10 kΩ or higher
      I35-6 (RL-) or I64-14 (II1-) - Body ground Always 10 kΩ or higher
      I64-18 (SLD1) - Body ground Always 10 kΩ or higher
