Circuit/System Verification

  1. Start and run the engine.
  2. With a scan tool, monitor that all eight ignition control (IC) circuit status parameters displays OK.
    • If the IC circuit status parameter displays, Short to Ground/Open, or Short to B+, continue with the Circuit/System Testing.
  3. Observe the Misfire Current counters using the scan tool. The counters should not be incrementing.
    • If the counters are incrementing for any of the cylinders, continue with Circuit/System Testing.
    • 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 Data List.
