CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P2759

DTC Code DTC Name
P2759 Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)

DESCRIPTION

The ECM uses the shift solenoid valve SLU to perform forward and reverse clutch control or lock-up clutch control.

A005HHYE04
DTC No.

DTC Detection Condition


  1. Diagnosis Condition

  2. Malfunction Status

  3. Malfunction Time

  4. Other

 Trouble Area
P2759

  1. The vehicle is being driven.

  2. An open or short in the shift solenoid valve SLU circuit

  3. 1 second or more

  4. 1 trip detection logic

  • Wire harness or connector

  • Continuously variable transaxle assembly

    (Shift solenoid valve SLU)

  • ECM

MONITOR DESCRIPTION

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

PROCEDURE


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


    1. A005HNAE25
      Text In Illustration
      *a

      Component without harness connected

      (Continuously Variable Transaxle Assembly (Transmission Wire))

      Disconnect the transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      6 (SLU+) - 13 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      6 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      13 (SLU-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the transmission wire connector.

    OK

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


    1. Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B23-47 (SLU-) - B23-48 (SLU+) 20°C (68°F) 5.0 to 5.6 Ω
      B23-47 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      B23-48 (SLU+) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the ECM connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. REPLACE ECM


    1. Replace the ECM Click here.

  4. PERFORM INITIALIZATION

    Note


    • Performing reset memory/initialization will clear the learned value of the deceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, deceleration sensor zero 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

      • Brake actuator assembly (Skid control ECU)

      • Oil pressure sensor

      • Deceleration sensor

    • After reset memory, always perform deceleration sensor (deceleration sensor zero point) calibration first, and then the CVT oil pressure calibration.

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

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


    1. Using the GTS, perform the reset memory, deceleration sensor zero point calibration and CVT oil pressure calibration Click here.

    2. Check for DTCs again Click here.
