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 lock-up control in response to the driving conditions.

DTC No.

DTC Detection Condition


  1. Diagnosis Condition

  2. Malfunction Status

  3. Malfunction Time

  4. Other

 Trouble Area
P2759

  1. While engine running

  2. An open circuit or short circuit 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 a 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. A01VFIIE02
      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
      4 (SLU+) - 9 (SLU-) 20°C (68°F) 5.1 to 5.5 Ω
      4 (SLU+) - Body ground or other terminals Always 10 kΩ or higher
      9 (SLU-) - Body ground or other terminals Always 10 kΩ or higher

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


    1. Reconnect the transmission wire connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance (for LHD)
      Tester Connection Condition Specified Condition
      B22-47 (SLU-) - B22-48 (SLU+) 20°C (68°F) 5.0 to 5.6 Ω
      B22-47 (SLU-) - Body ground Always 10 kΩ or higher
      B22-48 (SLU+) - Body ground Always 10 kΩ or higher
      Standard Resistance (for RHD)
      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 Always 10 kΩ or higher
      B23-48 (SLU+) - Body ground Always 10 kΩ or higher
