Manufacturer summary

Original wording in English

Supercedes SB23-L-001: The vehicle’s Check Engine Malfunction Indicator Lamp (MIL) may illuminate with DTC P2201 and/or P20EE set in the DEF Control Unit (DCU). If one or both 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.
