Manufacturer summary

Original wording in English

This bulletin provides information when there is an electrical system warning; DTC U046900 stored in the ECM.

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.
