Is the measured resistance within specification?
YES
- Substitute with a known - good ECM and check for proper operation. If the problem is corrected, replace ECM 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.
