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.
