CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P2716

DTC Code DTC Name
P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)

DESCRIPTION

The ECM uses signals to control shift solenoid valve SLT to provide optimum line pressure control. Shift solenoid valve SLT is also used during forward and reverse clutch engagement to control the oil pressure to the forward and reverse clutch.

  1. Diagnosis Condition

  2. Malfunction Status

  3. Malfunction Time

  4. Other

 Trouble Area
P2716

  1. The vehicle is being driven.

  2. There is an open or short circuit in the shift solenoid valve SLT circuit.

  3. 1 second or more

  4. 1 trip detection logic

  • Open or short in shift solenoid valve SLT circuit

  • Continuously variable transaxle assembly

  • ECM

MONITOR DESCRIPTION

This DTC indicates an open or short circuit in the shift solenoid valve SLT circuit. When there is an open or short circuit in the shift solenoid valve SLS circuit, the ECM detects the problem, illuminates the MIL and stores the DTC.

PROCEDURE


  1. INSPECT CONTINUOUSLY VARIABLE TRANSAXLE ASSEMBLY (TRANSMISSION WIRE) (SHIFT SOLENOID VALVE SLT)


    1. A005I7TE01
      Text in Illustration
      *a

      Component without harness connected

      (Continuously Variable Transaxle Assembly (Transmission Wire))

      Disconnect the B74 transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 (SLT+) - 8 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      3 (SLT+) - Body ground Always 10 kΩ or higher
      8 (SLT-) - Body ground Always 10 kΩ or higher

    OK

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


    1. Disconnect the B22 (for LHD) or B23 (for RHD) ECM connector.

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

      Standard Resistance (Check for Open) (for LHD)
      Tester Connection Condition Specified Condition
      B22-66 (SLT-) - B22-67 (SLT+) 20°C (68°F) 5.0 to 5.6 Ω
      Standard Resistance (Check for Open) (for RHD)
      Tester Connection Condition Specified Condition
      B23-66 (SLT-) - B23-67 (SLT+) 20°C (68°F) 5.0 to 5.6 Ω
      Standard Resistance (Check for Short) (for LHD)
      Tester Connection Condition Specified Condition
      B22-66 (SLT-) - Body ground Always 10 kΩ or higher
      B22-67 (SLT+) - Body ground Always 10 kΩ or higher
      Standard Resistance (Check for Short) (for RHD)
      Tester Connection Condition Specified Condition
      B23-66 (SLT-) - Body ground Always 10 kΩ or higher
      B23-67 (SLT+) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. PERFORM INITIALIZATION

    Note


    • Performing reset memory will clear the learned values of both the yaw rate sensor (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor 0 point calibration and CVT oil pressure calibration when replacing any of the parts shown in the following table:

      Replaced Part

      • Continuously variable transaxle assembly

      • ECM

      • Skid control computer (w/o VSC)

      • Oil pressure sensor

      • Deceleration sensor (w/o VSC)

      • Airbag sensor assembly (Yaw rate sensor) (w/ VSC)

    • After performing reset memory, always perform yaw rate sensor (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.

    • Always perform 0 point calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during 0 point calibration.


    1. Using the intelligent tester, perform reset memory, deceleration sensor 0 point calibration and CVT oil pressure calibration Click here.

    2. Check that no DTC is stored.
