Manufacturer summary

Original wording in English

This Preliminary information communicates to the technician the direction needed to address a Service headlamp message with DTC C103D sym28.

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.
