Ignition Checks: Notes
NOTE:
For circuit identification, see appropriate wiring diagram in the WIRING DIAGRAMS
article.
NOTE:
If an ignition failure occurs, ignition system may operate with limited ability using Failure Mode Effects Management (FMEM) or Hardware Limited Operation Strategy (HLOS). When this occurs, trouble codes should be present in PCM memory, engine may be hard to start, and timing will not change.
NOTE:
To identify ignition system type by application, see the ENGINE/VIN ID
article.
NOTE:
If vehicle does not start, go to CIRCUIT TEST A in the TESTS W/CODES
article.
