Self-Diagnostic System: Notes

When a system fault occurs, MIL (CHECK ENGINE light) on instrument cluster will illuminate to inform driver a problem exists. Light will remain on until fault goes away or system is serviced. If fault goes away (system parameter returns to normal operation) before it is serviced, MIL will turn off. Related fault code will still remain in PCM memory until cleared. Stored codes may later be accessed and identified by accessing Data Link Connector (DLC) with appropriate scan tool.
