DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P275613 Torque Converter Clutch Pressure Control Solenoid Control Circuit Open Open or short is detected in shift solenoid valve SLU circuit for 1 sec. or more while driving (1-trip detection logic)

  • Open or short in shift solenoid valve SLU circuit

  • Wiring harness connector

  • Transmission wire

  • Shift solenoid valve SLU

  • ECM

 Comes on DTC stored SAE: P2759

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 illuminate the MIL and store this DTC.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (SHIFT SOLENOID VALVE SLU CIRCUIT)


    1. B0059HCC70
      *a

      Front view of wire harness connector

      (to ECM)

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C20-3 (SLU+) - C20-2 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      C20-3 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      C20-2 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    OK

  2. CHECK HARNESS AND CONNECTOR (WIRING HARNESS CONNECTOR - ECM)


    1. Disconnect the C21 wiring harness connector.

    2. Disconnect the C20 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C21-14 (SLU+) - C20-3 (SLU+) Always Below 1 Ω
      C21-5 (SLU-) - C20-2 (SLU-) Always Below 1 Ω
      C21-14 (SLU+) or C20-3 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      C21-5 (SLU-) or C20-2 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)


    1. B0058FQC08
      *a

      Component without harness connected

      (Transmission Wire)

      Remove the wiring harness connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      A-11 (SLU+) - A-5 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      A-11 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      A-5 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    OK

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 5.0 to 5.6 Ω

    3. Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.

      OK
      Measurement Condition Specified Condition

      • Battery positive (+) with a 21 W bulb → Terminal 1

      • Battery negative (-) → Terminal 2

      		 Valve moves and makes an operating noise
