    3. Clear DTCs (Refer to DTC CHECK / CLEAR [08/2015 - 08/2018] ).
    4. Shuffle the arrangement of the ignition coil (among No. 1 to No. 8 cylinders).
      NOTE:

      Do not shuffle the connectors.

    5. Perform a simulation test.
    6. Check DTCs displayed on the Techstream.
      RESULT

      Result Proceed to
      Same DTC is output A
      Different ignition coil DTC is output B

      HINT: 

      Perform "Inspection After Repair" after replacing the ignition coil assembly (Refer to INITIALIZATION [08/2015 - 08/2017] ).

    Result:
