IGNITION SYSTEM SERVICE INFORMATION TROUBLESHOOTING IGNITION SYSTEM INSPECTION IGNITION COIL IGNITION TIMING SERVICE INFORMATION - GENERAL Some electrical components may be damaged if terminals or connectors are connected or disconnected while the ignition switch is ON and current is present.

When servicing the ignition system, always follow the steps in the troubleshooting on page. The ignition timing cannot be adjusted since the ignition control module (ICM) is factory preset. The ICM may be damaged if dropped. Also, if the connector is disconnected when current is flowing, the excessive voltage may damage the ICM. Always turn off the ignition switch before servicing. A faulty ignition system is often related to poor connections. Check those connections before proceeding.
