DTC P2713-12: Pressure Control Solenoid "D" Circuit Short to Battery [12/2019 - 10/2022]: Procedure

  1. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE (SOLENOID (SLT) VALVE) - ECM) 
    1. Disconnect the C54 ECM connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      C54-67 (SLT+) or C54-37 (SLT-) - Other terminals Always 10 kΩ or higher

      Result

      Proceed to

      *a Component without harness connected
      (Solenoid (SLT) Valve)

      Refer to DISASSEMBLY [12/2019 - 10/2022]

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      Solenoid (SLT) valve connector terminal 1 - terminal 2 20°C (68°F) 5.0 to 5.6 Ω
    3. Connect a positive (+) lead from the battery with a 21 W bulb to terminal 1 and a negative (-) lead to terminal 2 of the solenoid valve connector. Check that the valve moves and makes an operating sound.

      OK

      Valve moves and makes an operating sound.

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPAIR OR REPLACE TRANSMISSION WIRE. Refer to  COMPONENTS [12/2019 - 10/2022] 

    Result: 

    NG 

    REPLACE SOLENOID (SLT) VALVE. Refer to  COMPONENTS [12/2019 - 10/2022]
