Manufacturer summary

Original wording in English

Service Update. Certain trucks may falsely set fuel injector diagnostic trouble codes P026C and/or P20EE. Dealers will reprogram the engine control module (ECM).

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.
