P2759 Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical While the vehicle is driven, there is an open or short in the shift solenoid valve SLU circuit for 1 second or more (1 trip detection logic).

  • Wire harness or connector

  • Continuously variable transaxle assembly (Shift solenoid valve SLU)

  • ECM

 Comes on DTC stored

MONITOR DESCRIPTION

This DTC indicates an open or short in the shift solenoid valve SLU circuit. If there is an open or short in the shift solenoid valve SLU circuit, the ECM detects the malfunction, illuminates the MIL and stores this DTC.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)


    1. A0048QDC33
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the B115 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 B115 transmission wire connector.

      Result
      Proceed to
      OK
      NG

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


    1. Disconnect the B112*1 or B118*2 ECM connector.


      • *1: for LHD

      • *2: for RHD

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

      Standard Resistance (for LHD)
      Tester Connection Condition Specified Condition
      B112-43 (SLU+) - B112-42 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      B112-43 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      B112-42 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Standard Resistance (for RHD)
      Tester Connection Condition Specified Condition
      B118-43 (SLU+) - B118-42 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      B118-43 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      B118-42 (SLU-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the B112*1 or B118*2 ECM connector.


      • *1: for LHD

      • *2: for RHD
