Original wording in English

This engineering information (EI) closure ends the need for further information from technicians in regards to the Check Engine Lamp illuminated on the Driver Information Center (DIC) with P0494 Set.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
