Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.
  1. Verify that no other DTCs are set.
  2. Engine idling, verify there is no abnormal engine noise.
  3. Observe the Misfire Current Counters with a scan tool. The Misfire Current Counters should not be incrementing. Random misfires that are not steadily incrementing may be normal.
  4. If the vehicle passes the Circuit/System Verification test, then operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
