 ECM
P06DD
DTC Detection Drive Pattern DTC Detection Condition Trouble Area
Engine Idling

The power stage of oil pressure control device driver detects the over temperature error.

(1 trip detection logic)

 ECM

CAUTION / NOTICE / HINT

Note

When replacing the ECM, the ECM needs Registration and Initialization Click here.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. REPLACE ECM


    1. Replace the ECM Click here.

  2. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Clear the DTCs Click here.

    5. Turn the ignition switch off and wait for 30 seconds or more.

    6. Turn the ignition switch to ON.

    7. Turn the GTS on.

    8. Start the engine.

    9. Drive the vehicle with a stop-and-go city drive pattern for more than 15 minutes.

      CAUTION:

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

    10. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    11. Confirm that the DTC is not output again.
