Disconnect the Ignition Coil E and PCM connector and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connector.

Connect the GDS and go to ""Current Data"".

Monitor Ignition Coil E for misfires in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).

Any change in the values indicates a poor connection. Was a connector problem found?

	▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Power Circuit Inspection" procedure.

IG "OFF". Disconnect Ignition Coil connector.

IG "ON".

Measure voltage between power terminal of ignition coil harness connector and chassis ground.

Is the measured voltage within specification ?

	▶ Go to "Control Circuit Inspection" procedure.
	▶ Check for short to ground or open in power supply circuit, from relay to fuse to ignition coil connector. ▶ Repair short to ground or open in harness. Go to "Verification of Vehicle Repair" procedure.

IG "OFF". Disconnect ignition coil connector and PCM connector.

Measure resistance between power and control terminals of ignition coil harness connector.

Is the measured resistance within specification?

	▶ Go to "Check short to ground in harness' as follows.
	▶ Repair short to battery in harness, and go to "Verification of Vehicle Repair" procedure.

IG "OFF". Disconnect ignition coil connector and PCM connector.

Measure resistance between control terminal of ignition coil harness connector and chassis ground.

Is the measured resistance within specification?

	▶ Go to "Check open in harness" as follows.
	▶ Repair short to ground in harness. Go to "Verification of Vehicle Repair" procedure.

IG "OFF". Disconnect ignition coil connector and PCM connector.

Measure resistance between control terminal of Ignition Coil harness connector and IG Coil control terminal of PCM harness connector.

Is the measured resistance within specification?

	▶ Go to "Component Inspection" procedure.
	▶ Repair open in harness. Go to "Verification of Vehicle Repair" procedure.
