Manufacturer summary

Original wording in English

The vehicle’s Malfunction Indicator Lamp (MIL) may illuminate with DTC P22FB and/or P22FE set in the DEF Control Unit (DCU). If one or more of the preceding DTCs are present, first follow the diagnostic for the DTC(s) in question. 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.
