PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - TELEMATICS TRANSCEIVER)


    1. Disconnect the I154 radio receiver assembly connector.

    2. Disconnect the I100 telematics transceiver connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      I154-13 (VOR+) - I100-3 (VOT+) Always Below 1 Ω
      I154-14 (VOR-) - I100-5 (VOT-) Always Below 1 Ω
      I154-15 (VOT+) - I100-7 (VOR+) Always Below 1 Ω
      I154-16 (VOT-) - I100-6 (VOR-) Always Below 1 Ω
      I154-13 (VOR+) - Body ground Always 10 kΩ or higher
      I154-14 (VOR-) - Body ground Always 10 kΩ or higher
      I154-15 (VOT+) - Body ground Always 10 kΩ or higher
      I154-16 (VOT-) - Body ground Always 10 kΩ or higher
      Result
