Manufacturer summary

Original wording in English

On certain vehicles equipped with a 6.6L diesel engine (RPO L5P), the DEF tank connector may overheat and set the following diagnostic codes (P10D9, P143C and P10F3), which will result in reduced engine speed. Dealers are to reprogram the reductant control module.

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.
