Ignition System Service

CAUTION:
^ The ignition coils secondary voltage output capabilities are very high-more than 40,000 volts. Avoid body contact with high ignition voltage secondary components when the engine is running, to prevent personal injury.
^ In order to prevent personal injury, always treat the high voltage cables and connectors as if the voltage is present.

Consider the following important information when servicing the ignition system:
^ The ignition timing is not adjustable. A timing indicator and timing marks are still visible at the crankshaft pulley, but are not used to set or adjust ignition timing. The powertrain control module provides all ignition timing adjustments electronically.
^ Be careful not to damage the secondary ignition wires or boots when servicing the ignition system. Rotate each ignition wire boot in order to loosen the boot from the spark plug or the ignition coil tower before removing the wire. Never pierce a secondary ignition wire or boot for any testing purposes. Future ignition system problems are guaranteed if pinpoints or test lights are pushed through the secondary ignition wire insulation during component testing.
^ Do not use a conventional tachometer in order to check engine speed on this ignition system. An inductive type pick-up will not provide reliable engine speed information. Use a scan tool in order to monitor engine RPM.
