IGNITION SYSTEM
SERVICE INFORMATION
GENERAL
• Some electrical components may be damaged if terminals or connectors are connected or disconnected while the igni-
tion switch is ON and current is present.
• When servicing the ignition system, always follow the steps in the troubleshooting sequence (page 18-4).
• This motorcycle's Ignit ion Control Module (ICM) is built into the Engine Control Module (ECM).
• The ignition timing does not normally need to be adjusted since the ECM is factory preset.
• The ECM may be damaged if dropped. Also if the connector is disconnected when current is flowing, the excessive volt-
age may damage the module. Always turn off the ignition switch before servicing.
• A faulty ignition system is often related to poor connections. Check t hose connectio ns before proceeding. Make sure the
battery is adequately charged. Using the starter motor with a weak battery resu lts in a slower engine cranking speed as
well as no spark at the spark plug.
• Use spark plugs of the correct heat range. Using spark plugs with an incorrect heat range can damage the engine.
• This motorcycle features direct ignition coils, where the ignition coils and spark plug caps are integrated.
• Refer to the Throttle Position (TP) sensor inspection (page 5-80), cam pulse generator inspection (page 5-79) and ECM
inspection (page 5-83).
