IGNITION SYSTEM
SERVICE INFORMATION
GENERAL
• The ECM/PCM 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.
• When servicing the ignition system, always follow the steps in the troubleshooting table (page 5-5).
• Some electrical components may be damaged if terminals or connectors are connected or disconnected while the ignition switch
is turned to ON position and current is present.
• A faulty ignition system is often related to poorly connected or corroded connections. 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.
• For ECM/PCM service (page 4-67).
• Refer to following components informations:
– Ignition switch (page 22-24)
– Engine stop switch (page 22-25)
– Bank angle sensor (page 4-65)
– Sidestand switch (page 22-28)
– Neutral switch (page 22-27)
• The following color codes are used throughout this section.
