Original wording in English

12 - 002 Diagnosis Procedure for P202E (DCU) Associated with P204F (ECU) Some engines may erroneously record a P202E DTC in the DCU along with a P204F in the ECU. This fault condition is due to DCU software misdetection of DEF system pressure being delivered to the DEF injector.

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.
