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

   
   
   1. 

      *a	Front view of wire harness connector (to Radio Receiver Assembly)
      *b	Front view of wire harness connector (to Telematics Transceiver)

      Disconnect the O134 radio receiver assembly connector.

   2. Disconnect the O135 telematics transceiver connector.

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

      Standard Resistance

      Tester Connection Condition Specified Condition O134-7 (VOR+) - O135-3 (VOT+) Always Below 1 Ω O134-6 (VOR-) - O135-5 (VOT-) Always Below 1 Ω O134-3 (VOT+) - O135-7 (VOR+) Always Below 1 Ω O134-5 (VOT-) - O135-6 (VOR-) Always Below 1 Ω O134-7 (VOR+) - Body ground Always 10 kΩ or higher O134-6 (VOR-) - Body ground Always 10 kΩ or higher O134-3 (VOT+) - Body ground Always 10 kΩ or higher O134-5 (VOT-) - Body ground Always 10 kΩ or higher

      Result
      Proceed to OK NG
