IGNITION SYSTEM

ON-VEHICLE INSPECTION

INSPECT IGNITION COIL
a. Disconnect the high-tension cords from the ignition coil.
b. Disconnect the ignition coil connectors.




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

Secondary coil resistance:
- Cold: 9.7 - 16.7 kOhms
- Hot: 12.4 - 19.6 kOhms

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

d. Connect ignition coil connectors.
e. Connect the high-tension cords from the ignition coils.
