CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P282B

DTC Code DTC Name
P282B Pressure Control Solenoid "K" Electrical (Shift Solenoid Valve SLS)

DESCRIPTION

The ECM uses shift solenoid valve SLS to control the secondary pulley pressure and belt clamping pressure according to the input shaft torque. Additionally, shift solenoid valve SLS is used to control the forward and reverse clutch hydraulic pressure when the forward and reverse clutch is engaged.

  1. Diagnosis Condition


    • The vehicle is being driven.

  2. Malfunction Status


    • There is an open or short circuit in the shift solenoid valve SLS circuit.

  3. Malfunction Time


    • 1 second or more

  4. Other


    • 1-trip detection logic

  • Wire harness or connector

  • Continuously variable transaxle assembly (Shift solenoid valve SLS)

  • ECM

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLS)


    1. A01T9G9C34
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the B90 transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 (SLS+) - 8 (SLS-) 20°C (68°F) 5.0 to 5.6 Ω
      3 (SLS+) - Body ground and other terminals Always 10 kΩ or higher
      8 (SLS-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the B90 transmission wire connector.

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


    1. Disconnect the B31 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B31-73 (SLS+) - B31-72 (SLS-) 20°C (68°F) 5.0 to 5.6 Ω
      B31-73 (SLS+) - Body ground and other terminals Always 10 kΩ or higher
      B31-72 (SLS-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the B31 ECM connector.

  4. PERFORM INITIALIZATION

    Note


    • Performing Reset Memory will clear the learned value of the yaw rate and acceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform Reset Memory, yaw rate and acceleration 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

      • Oil pressure sensor

      • Airbag sensor assembly (Yaw rate and acceleration sensor)

    • After performing Reset Memory, always perform yaw rate and acceleration sensor (deceleration sensor zero point) calibration first, and then CVT oil pressure calibration.

    • Always perform calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during calibration.


    1. Using the GTS, perform Reset Memory, deceleration sensor zero point calibration and CVT oil pressure calibration.
