IGNITION SYSTEM
SERVICE INFORMATION
GENERAL
NOTICE
•
The PCM may be damaged if dropped. Also, if the connector is disconnected when current
is
flowing, the excessive
voltage may damage the PCMIECM. Always turn the ignition switch
to
OFF before selVicing.
•
Use spark plugs with the correct heat range. Using spark plugs with an incorrect heat range can damage the engine.
•
Some electrical components may be damaged if terminals or connectors are connected or disconnected whi le the igni-
tion switch is ON and cu rrent is present.
•
When servicing the ignition system, always follow the steps in the troubleshooting chart (page 22-4),
•
This ignition system is controlled by PCM.
•
The transistorized ignition system uses an electrically controlled ignition timing system. No adjustments can be made
to the ignition timing.
•
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.
