DTC P2716: Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT): Procedure

WARNING: This page is about a different car, the 2011 Toyota Matrix. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT TRANSMISSION WIRE (SLT) 
    1. Disconnect the transmission wire connector from the transaxle.

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

      Standard resistance

      Tester Connection Condition Specified Condition
      2 (SLT+) - 7 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for short)

      Tester Connection Condition Specified Condition
      2 (SLT+) - Body ground Always 10 kΩ or higher
      7 (SLT-) - Body ground Always ↑

    NG → See step   3 

    OK: Go to next step 

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) 
    1. Connect the transmission wire connector to the transaxle.

    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester Connection Condition Specified Condition
      B29-76 (SLT+) - B29-75 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
    4. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for short)

      Tester Connection Condition Specified Condition
      B29-76 (SLT+) - Body ground Always 10 kΩ or higher
      B29-75 (SLT-) - Body ground Always

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → See step   5 

  3. INSPECT SHIFT SOLENOID VALVE SLT 
    1. Remove the shift solenoid valve SLT.

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

      Standard resistance

      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 5.0 to 5.6 Ω
    3. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

      OK

      The solenoid makes an operating sound.

    NG → See step   6 

    OK → See step   4 

  4. REPAIR OR REPLACE TRANSMISSION WIRE. Refer to  REMOVAL 
  5. REPLACE ECM. Refer to  REMOVAL 
  6. REPLACE SHIFT SOLENOID VALVE SLT. Refer to  DISASSEMBLY
