  • When replacing the telematics transceiver, make sure to replace it with a new one.

  • When replacing the radio receiver assembly, always replace it with a new one.

    If a radio receiver assembly which was installed to another vehicle is used, the following may occur:


    • A communication malfunction DTC may be stored.

    • The radio receiver assembly may not operate normally.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - ANTENNA CORD SUB-ASSEMBLY [I/P])


    1. Disconnect the G53 radio receiver assembly connector.

    2. Disconnect the G152 antenna cord sub-assembly (I/P) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G53-13 (VOR+) - G152-4 (VOT+) Always Below 1 Ω
      G53-14 (VOR-) - G152-6 (VOT-) Always Below 1 Ω
      G53-13 (VOR+) - Body ground Always 10 kΩ or higher
      G53-14 (VOR-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK

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

      Standard
      Tester Connection Condition Specified Condition
      A-4 (VOT+) - Body ground Calling while using the operator service A waveform synchronized with the sent voice is output
      A-7 (VOT-) - Body ground Calling while using the operator service A waveform synchronized with the sent voice is output
      Result
      Proceed to
      OK
      NG
