IG "OFF" and disconnect ignition coil connector.
Measure resistance between power and signal terminals of ignition coil connector. (Measurement "A")

Measure resistance between power terminal of ignition coil connector and out terminal of secondary ignition coil. (Measurement "B")

SPECIFICATION :

IGNITION COIL SPECIFICATION

Resistance	Primary Coil	Secondary Coil
Resistance	0.62Ω ± 10%	7.0kΩ ± 15%

Is the measured resistance within specification?
YES:
- Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO:
- Substitute with a known - good Ignition Coil and check for proper operation. If the problem is corrected, replace Ignition Coil and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
