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 table on
· This vehicle's Ignition Control Module (ICM) is built in the engine control module (ECM).
· The ignition timing cannot 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
voltage may damage the ECM. 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 a weak battery results in a slower engine
cranking speed as well as no spark at the spark plug.
· This vehicle's spark plug is equipped with iridium type electrode. Do not use any spark plug other than specified.
· 11-8 for ignition pulse generator removal/installation.
