Original wording in English

DTC P225C CALIBRATION UPDATE ? REPROGRAM DEF CONTROL UNIT (DCU). Follow the diagnostic for this DTC. If no mechanical fault can be found during normal diagnosis, follow the service procedure in this bulletin to correct the concern.

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.
