DTC P2714: Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT): Procedure

WARNING: This page is about a different car, the 2010 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P2714) 
    1. Connect Techstream to the DLC3.
    2. Start the ignition and turn Techstream on.
    3. Enter the following items: "Powertrain / ECT / Trouble Codes".
    4. Read the DTCs using Techstream.

      Only "P2714" is output A
      "P2714" and other DTCs B

      HINT: 

      If a solenoid is stuck ON, DTCs for several solenoids including the malfunctioning solenoid will be detected.

    A → See step   4 

    B: Go to next step 

  2. PERFORM ACTIVE TEST USING TECHSTREAM (SHIFT SOLENOID VALVE SLT) 
    NOTE:
    • Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature: 50 to 80°C (122 to 176°F)
    • Be sure to prevent SST hose from interfering with the exhaust pipe.
    • This check must be conducted after checking and adjusting the engine.
    • Perform the test with the A/C OFF.

    HINT: 

    Using Techstream to perform Active Test allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Test early in troubleshooting is one way to save diagnostic time.

    Data List information can be displayed while performing Active Test.

    1. Turn the engine switch off.
    2. Lift the vehicle up.
    3. Remove the test plug on the transmission case center right side and connect SST.

      • SST: 09992-00095 
        • 09992-00231
        • 09992-00271
    4. Lower the vehicle.
    5. Fully apply the parking brake and chock the 4 wheels.
    6. Connect Techstream to the DLC3.
    7. Start the engine.
    8. Warm up the ATF (Automatic Transmission Fluid).
    9. Measure the line pressure when the engine is idling.
    10. Turn on the tester.
    11. Enter the following items: Powertrain / ECT / Active Test".
    12. Follow the instructions on the tester and perform the Active Test.
    13. Measure the line pressure with SST.
      Item Test Details
      Activate the Solenoid (SLT)* [Test Details]
      Operate the shift solenoid SLT and raise the line pressure.
      [Vehicle Condition]
      • Vehicle Stopped
      • IDL: ON

      HINT: 
      OFF: Line pressure up (When the active test of "Activate the Solenoid (SLT)" is performed, the ECM commands the SLT solenoid to turn off).
      ON: No action (normal operation)

      *: "Activate the Solenoid (SLT)" in the Active Test is performed to check that the line pressure changes by connecting the SST to the automatic transaxle. The same SST is used in the HYDRAULIC TEST. Refer to HYDRAULIC TEST as well.

      HINT: 

      The pressure values in Active Test and HYDRAULIC TEST are different from each other.

      OK

      The line pressure changes as specified when performing the Active Test.

    NG → See step   5 

    OK: Go to next step 

  3. PERFORM ACTIVE TEST USING TECHSTREAM (SHIFTING TEST) 
    NOTE:

    This test should always be performed with at least 2 people.

    1. Connect Techstream to the DLC3.
    2. Turn the ignition switch on (IG) and turn Techstream on.
    3. Enter the following items: "Powertrain / ECT / Active Test".

      HINT: 

      Comparing the shift position commanded by the Active Test with the actual shift position enables confirmation of the problem. Refer to FAIL-SAFE CHART .

      Item Test Details Diagnostic Note
      Control the Shift Position [Test Details]
      Operate the shift solenoid valve and set each shift position by yourself.
      [Others]
      • Press "→" button: Shift up
      • Press "←" button: Shift down
      		 Possible to check the operation of the shift solenoid valves.
      NOTE:
      • This test can be conducted when the vehicle is stopped.
      • When shifting gears using the Active Test function, do not operate the accelerator pedal for 2 seconds before and after shifting gears.

      HINT: 

      The shift position commanded by the TCM is shown in the Data List/Shift Status display on Techstream.

    4. Check the vehicle speed and the gear position when the engine speed is 1,000 RPM.

      HINT: 

      Because the torque converter clutch has not engaged, it may be difficult to obtain the speeds specified in 4th, 5th, and 6th gear, however a difference of speed should still be evident following each gear change.

      Standard

      1st 2nd 3rd 4th 5th 6th
      5 to 7.5 mph (8 to 12 km/h) 9.3 to 11.8 mph (15 to 19 km/h) 13.0 to 15.5 mph (21 to 25 km/h) 19.3 to 21.7 mph (31 to 35 km/h) 27.3 to 29.8 mph (44 to 48 km/h) 32.3 to 34.8 mph (52 to 56 km/h)
    5. Compare the TCM gear shift command and the actual gear position.

      HINT: 

      • *1: Neutral
      • *2: If the shift solenoid SLT is stuck on, the line pressure will be low. Therefore, the amount of torque that can be transmitted by each gear is lower than the normal limit. When the engine power exceeds this lowered limit, the engine speed will increase freely.
      • *3: When shift solenoid SLT is stuck OFF, gear shifting is normal.
