PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - TELEMATICS TRANSCEIVER)


    1. Disconnect the H158 multi-media module receiver assembly connector.

    2. Disconnect the H159 telematics transceiver connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      H158-7 (VOR+) - H159-3 (VOT+) Always Below 1 Ω
      H158-6 (VOR-) - H159-5 (VOT-) Always Below 1 Ω
      H158-7 (VOR+) - Body ground Always 10 kΩ or higher
      H158-6 (VOR-) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
