Pressure Control Solenoid "K" Circuit Short to Ground or Open

An open or short to ground is detected in the shift solenoid valve SLS circuit for 1 second or more (1-trip detection logic).

  • Transmission valve body assembly (Shift solenoid valve SLS)
  • Transmission wire
  • Harness and connector
  • TCM

SAE Code:

P282F

MONITOR DESCRIPTION

This DTC indicates an open or short to ground in the shift solenoid valve SLS circuit. If there is an open or short to ground in the shift solenoid valve SLS circuit, the TCM detects the malfunction, illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

HINT:

  • After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
  • When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.

    Click here

  1. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  2. Turn the ignition switch off and wait for 2 minutes or more.
  3. Turn the ignition switch to ON and turn the GTS on.
  4. Start the engine.
  5. Perform the D Position Shift Test inspection in Road Test. [*1]

    HINT:

    [*1]: Normal judgment procedure.

    The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  6. Stop the vehicle.
  7. Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
  8. Input the DTC: P282814.
  9. Check the DTC judgment result.

    GTS Display

    Description

    NORMAL

    • DTC judgment completed
    • System normal

    ABNORMAL

    • DTC judgment completed
    • System abnormal

    INCOMPLETE

    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A

    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
