Manufacturer summary

Original wording in English

Service Update Bulletin. The affected vehicles may incorrectly present the MIL/Service Engine Soon Light being illuminated and technicians may find DTC P11D5. Dealers are to reprogram the engine control module. This correction applies to vehicles registered in cold weather US states and Canadian Provinces.

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.
