IGNITION SYSTEM
SERVICE INFORMATION
GENERAL
• When servicing the ignition system, always follow the steps in the troubleshooting sequence on page 17-4.
• The ignition timing cannot be adjusted since the Ignition Control Module oeM) is factory preset.
• The Ignition control module oeM) may be damaged if dropped. Also, if the connector is disconnected when current is
flowing, the excessive voltage may damage the module.
• A faulty ignition system is often re lated to poor connections. Check connections before proceeding.
• Use a spark plug of the correct heat range. Using a spark plug with an incorrect heat range can damage the engine.
