IGNITION SYSTEM
SERVICE INFORMATION
IGNITION SYSTEM
GENERAL
• The ECM may be damaged if dropped. Also if the connector is disconnected when current is flowing, the excessive voltage may
damage the module. Always turn off the ignition switch before servicing.
• Use spark plug of the correct heat range. Using a spark plug with an incorrect heat range can damage the engine.
• Some electrical components may be damaged if terminals or connectors are connected or disconnected while the ignition switch
is turned ON and current is present.
• A faulty ignition system is often related to poorly connected or corroded terminals. Check those connections before proceeding.
• Make sure the battery is adequately charged. Using the starter motor with a weak battery results in a slower engine cranking
speed as well as no spark at the spark plug.
• The ignition timing cannot be adjusted since the ECM is factory preset.
• When servicing the ignition system, always follow the steps in the troubleshooting table (page 5-3).
