Manufacturer summary

Original wording in English

This Preliminary information communicates information to dealership on how to clear a B1001 DTC after replacing the BCM or SDM.

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.
