DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P271313 Pressure Control Solenoid "D" Circuit Open While the engine is running, a short or open is detected in the shift solenoid valve SLT circuit for 1 second (1-trip detection logic).

  • Harness and connector

  • Transmission wire

  • Shift solenoid valve SLT

  • ECM

 Comes on DTC stored SAE Code: P2716

MONITOR DESCRIPTION

When an open or short in the shift solenoid valve SLT circuit is detected, the ECM determines that there is a malfunction. The ECM will illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

Tech Tips

After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the engine switch off and wait for 2 minutes or more.

  5. Turn the engine switch on (IG) and turn the GTS on.

  6. Start the engine.

  7. Wait for 2 seconds or more with the engine running.

  8. Enter the following menus: Powertrain / Transmission / Utility / All Readiness.

  9. Input the DTC: P271313.

  10. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT) - ECM)


    1. Disconnect the F66 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F66-67 (SLT+) - F66-37 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      F66-67 (SLT+) or F66-37 (SLT-) - Body ground Always 10 kΩ or higher

  3. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)


    1. Disconnect the F61 transmission wire connector.

    2. Disconnect the F66 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F61-3 (SLT+) - F66-67 (SLT+) Always Below 1 Ω
      F61-4 (SLT-) - F66-37 (SLT-) Always Below 1 Ω
      F61-3 (SLT+) or F66-67 (SLT+) - Body ground Always 10 kΩ or higher
      F61-4 (SLT-) or F66-37 (SLT-) - Body ground Always 10 kΩ or higher

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      Terminal 1 of the shift solenoid valve SLT - 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 shift solenoid valve connector. Check that the valve moves and makes an operating sound.

      OK
      Valve moves and makes an operating sound.
