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.

 Trouble Area
P282B

  1. The vehicle is being driven.

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

  3. 1 second

  4. 1 trip detection logic

  • Open or short in shift solenoid valve SLS circuit

  • Continuously variable transaxle assembly

  • ECM

MONITOR DESCRIPTION

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

INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLS)


    1. A01IPWEE11
      Text in Illustration
      *1

      Component without harness connected

      (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
      3 (SLS+) - 8 (SLS-) 20°C (68°F) 5.0 to 5.6 Ω
      3 (SLS+) - Body ground Always 10 kΩ or higher
      8 (SLS-) - Body ground Always 10 kΩ or higher

    NG

      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
      C68-53 (SLS-) - C68-54 (SLS+) 20°C (68°F) 5.0 to 5.6 Ω
      C68-53 (SLS-) - Body ground Always 10 kΩ or higher
      C68-54 (SLS+) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. REPLACE ECM

  4. PERFORM INITIALIZATION

    Note


    • Performing reset memory will clear the learned values of both the yaw rate sensor (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor 0 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

      • Yaw rate sensor

    • After performing reset memory, always perform yaw rate sensor (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.

    • Always perform 0 point calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during 0 point calibration.


    1. Using the intelligent tester, perform reset memory, deceleration sensor 0 point calibration and CVT oil pressure calibration Click here.

    2. Check that no DTC is stored.
