Manufacturer summary

Original wording in English

This Preliminary information communicates a false setting of DTCU0121 in the FVCM due to a FVCM software anomaly. Code U0121 will set and be moved to history in the FVCM with each ignition cycle.

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.
