    4. Clear the DTCs, refer to DTC CHECK / CLEAR .
    5. Shuffle arrangement of the ignition coils with igniters (among No. 1 to No. 6 cylinders).
      NOTE:

      Do not shuffle the connectors.

    6. Perform a simulation test.
    7. Check the DTCs displayed on the tester.

      Result

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

    B → See step   5 

    A → See step   6
