This bulletin provides ignition coil replacement guidelines and ignition coil installation and removal procedures.

IGNITION COIL DIAGNOSIS

Do not replace the ignition coil unless it can be verified that it is the only cause for the condition and/or a related diagnostic trouble code (DTC).

If diagnosis leads to the ignition module assembly, and it can not be verified that the ignition coil is faulty, the entire ignition module assembly must be replaced. Refer to "Ignition Coil Inspection" to inspect the ignition coil.

IGNITION COIL INSPECTION

The ignition coil can be checked using the following procedure.

1. Inspect ignition coil for corrosion.

^ If excessive corrosion is present on the ignition coil terminals, replace the ignition coil only, and verify that the vehicle conditions and/or DTCs are no longer present.

^ If corrosion is not present on the ignition coil terminals, refer to step 2.

2. Check resistance between ignition coil towers.

^ If resistance between the ignition coil towers is not within the specified range of 8-15 K ohms, replace the ignition coil.

Refer to "Procedure" in this bulletin to replace the ignition coil.
