P282B

  1. The vehicle is being driven.

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

  3. 1 second

  4. 1 trip detection logic

  • Wire harness or connector

  • Continuously variable transaxle assembly

    (Shift solenoid valve SLS)

  • ECM

MONITOR DESCRIPTION

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

PROCEDURE


  1. INSPECT CONTINUOUSLY VARIABLE TRANSAXLE ASSEMBLY (TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLS))


    1. A005HNAE28
      Text in Illustration
      *a

      Component without wire 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
      5 (SLS+) - 12 (SLS-) 20°C (68°F) 5.0 to 5.6 Ω
      5 (SLS+) - Body ground and other terminals Always 10 kΩ or higher
      12 (SLS-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the transmission wire connector.

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


    1. Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B23-72 (SLS-) - B23-73 (SLS+) 20°C (68°F) 5.0 to 5.6 Ω
      B23-72 (SLS-) - Body ground and other terminals Always 10 kΩ or higher
      B23-73 (SLS+) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the ECM connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. REPLACE ECM

  4. PERFORM INITIALIZATION

    Note


    • Performing reset memory/initialization will clear the learned value of the deceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, deceleration 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

      • Brake actuator assembly (Skid control ECU)

      • Oil pressure sensor

      • Deceleration sensor

    • After reset memory, always perform deceleration sensor (deceleration sensor zero point) calibration first, and then the CVT oil pressure calibration.

    • Always perform the zero point calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during the zero point calibration.


    1. Using the GTS, perform the reset memory, deceleration sensor zero point calibration and CVT oil pressure calibration Click here.

    2. Check for DTCs again Click here.
