Component Inspection
- 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")RESISTANCE SPECIFICATION
Resistance(Ω) 'A' Primary Coil 'B' Secondary Coil 0.62 ± (20°C) (68°F) 7.0k ± 15% (20°C) (68°F) - 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.
