TEST ACTION APPLICABILITY
6 Turn the ignition off.
Disconnect the Ignition Coil harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the Coil Control circuit between the Ignition Coil harness
connector and the special tool #8815 terminal.
Is the resistance below 5.0 ohms?
All
Yes → Go To 7
No → Repair the Coil Control circuit for an open.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
7 Turn the ignition off.
Disconnect the Ignition Coil harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the Coil Control circuit in the Ignition
Coil harness connector.
Is the resistance below 100k ohms?
All
Yes → Repair the Coil Control circuit for a short to ground.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
No → Go To 8
8 NOTE: Before continuing, check the PCM harness connector terminals for corrosion,
damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.

- Loose or broke electrode
NOTE: Lightly tap the bottom of the spark plug on a solid surface. The
electrode in the spark plug should not move.
Were any of the above condition present?
All
Yes → Replace the Spark Plug.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
