Power Circuit Inspection

  1. Check voltage of power circuit
    1. Key "OFF".
    2. Disconnect FTPS connector.
    3. Key "ON".
    4. Measure the voltage between terminal 1 of FTPS harness connector and chassis ground.

      Specification: Approx. 5V

    5. Is the measured voltage within specification ?

      YES  : --> Go to "SIGNAL CIRCUIT INSPECTION " procedure.

      NO  : --> Go to "Check Open or Short in power circuit inspection" procedure.

  2. Check Open or Short in power circuit inspection
    1. Key "OFF".
    2. Disconnect FTPS harness connector and ECM/PCM harness connector.
    3. Measure the resistance between terminal 1 of FTPS harness connector and terminal 3/C01-2 of ECM/PCM harness connector. (A/T)

      Measure the resistance between terminal 1 of FTPS harness connector and terminal 50/C01 of ECM/PCM harness connector. (M/T)

      Specification: Approx. 1Ω

    4. Is the measured resistance within specification ?

      YES  : --> Go to "COMPONENT INSPECTION " procedure.

      NO  : --> Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
