Diagnostic Aids

* Inspect the ignition coils for aftermarket devices. An aftermarket device connected to the ignition coil circuits, may cause this DTC to set.

* If the condition is intermittent, moving the related harnesses and connectors, with the engine operating, while monitoring the appropriate scan

tool Misfire Current Cylinder parameter may help to isolate the condition.
