Manufacturer summary

Original wording in English

CBR - The Purpose of this CBR is to assist with diagnostics for fault code U300049 on the Battery Power Management Unit (BPMU).

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.
