Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)

An open or short is detected in the shift solenoid valve SLU circuit for 1 second or more while driving (1-trip detection logic).

  • Open or short in shift solenoid valve SLU circuit

  • Shift solenoid valve SLU

  • TCM

Comes on

DTC stored

MONITOR DESCRIPTION

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

PROCEDURE

  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)

    1. C207057C20

      *a

      Component without TCM connected

      (Transmission Wire)

      Remove the TCM.

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      11 (SLU+) - 5 (SLU-)

      20°C (68°F)

      5.0 to 5.6 Ω

      11 (SLU+) - Body ground

      Always

      10 kΩ or higher

      5 (SLU-) - Body ground

      Always

      10 kΩ or higher

      11 (SLU+) - All other terminals except 5 (SLU-)

      Always

      10 kΩ or higher

      5 (SLU-) - All other terminals except 11 (SLU+)

      Always

      10 kΩ or higher

    Result

  2. INSPECT SHIFT SOLENOID VALVE SLU

    1. C197715C16

      *1

      Shift Solenoid Valve SLU

      Remove shift solenoid valve SLU.

    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
