PROCEDURE


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


    1. B005O02C09
      *a

      Front view of wire harness connector

      (to Radio Receiver Assembly)
      *b

      Front view of wire harness connector

      (to Telematics Transceiver)

      Disconnect the J130 radio receiver assembly connector.

    2. Disconnect the J131 telematics transceiver connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J130-7 (VOR+) - J131-3 (VOT+) Always Below 1 Ω
      J130-6 (VOR-) - J131-5 (VOT-) Always Below 1 Ω
      J130-7 (VOR+) or J131-3 (VOT+) - Body ground Always 10 kΩ or higher
      J130-6 (VOR-) or J131-5 (VOT-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT TELEMATICS TRANSCEIVER

      *a

      Component with harness connected

      (Telematics Transceiver)

      Check for pulses according to the value(s) in the table below.

      Standard
      Tester Connection Condition Specified Condition
      J131-3 (VOT+) - Body ground Receiving a call while using the operator service A waveform synchronized with the received voice is output
      J131-5 (VOT-) - Body ground Receiving a call while using the operator service A waveform synchronized with the received voice is output
      Result
      Proceed to
      OK
      NG

    OK
