Ignition Checks: Notes

NOTE: For circuit identification, see appropriate wiring diagram in the appropriate WIRING DIAGRAMS article in the ENGINE PERFORMANCE section (See above).

NOTE: If an ignition failure occurs, ignition system may operate with limited ability using Failure Mode Effects Management (FMEM). When this occurs, trouble codes should be present, engine may be hard to start and dwell, and timing will not change.

NOTE: To identify ignition system type by application, see ENGINE/VIN ID article in ENGINE PERFORMANCE.
