IGNITION SYSTEM
GENERAL INSTRUCTIONS
• 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 above.
• The ignition timing cannot be adjusted since the ignition control module is already
adjusted in factory.
• The ignition control module or ECU maybe damaged if dropped or the connector is
disconnected when the key is "ON", the excessive voltage may damage the ignition
control module or ECU. Always turn off the ignition switch before servicing.
• A faulty ignition system is often related to poor connections. Check those connections
before proceeding.
• Make sure the battery is adequately charged. Using the starter motor with weak
battery results in a slower engine cranking speed as well as no spark at the spark
plug.
• Use a spark plug of the correct heat range. Using spark plug with an incorrect heat
range can damage the engine.
TROUBLESHOOTING
No peak voltage
• Short circuit in engine stop switch or ignition switch wire.
• Faulty engine stop switch or ignition switch.
• Loose or poorly connected ignition control module connectors.
• Open circuit or poor connection in ground wire of the ignition control module.
• Faulty crank position sensor.
• Faulty ignition control module.
Peak voltage is normal, but no spark jumps at the plug
• Faulty spark plug or leaking ignition coil secondary current.
• Faulty ignition coil.
