ON-VEHICLE INSPECTION

INSPECT IGNITION COILS

a. Remove the ignition coil assembly.





b. Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.





Primary coil resistance

If the resistance is not as specified, replace the ignition coil.





c. Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.





Secondary coil resistance

If the resistance is not as specified, replace the ignition coil.

d. Reinstall the ignition coil assembly.
