    Result: 

    NEXT 

    See step  6

  6. CONFIRM WHETHER DTC OUTPUT RECURS 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Clear DTCs (Refer to DTC CHECK / CLEAR [08/2015 - 08/2018] ).
    5. Start the engine.
    6. Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
    7. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
    8. Read DTCs.
      RESULT

      Result Proceed to
      No DTC is output A
      P1340, P1342 and/or P1343 are output B

      HINT: 

      If the engine does not start, replace the ECM.

    Result: 

    A 

    END 

    Result: 

    B
