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


    • The vehicle is being driven.

  2. Malfunction Status


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

  3. Malfunction Time


    • 1 second or more

  4. Other


    • 1-trip detection logic

  • Wire harness or connector

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)


    1. A01T9G9C32
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the B90 transmission wire connector.

    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
      2 (SLT+) - Body ground and other terminals Always 10 kΩ or higher
      7 (SLT-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the B90 transmission wire connector.

      Result
      Proceed to
      OK
      NG

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


    1. Disconnect the B186 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B186-39 (SLT+) - B186-38 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      B186-39 (SLT+) - Body ground and other terminals Always 10 kΩ or higher
      B186-38 (SLT-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the B186 ECM connector.

      Result
      Proceed to
      OK
      NG
