Manufacturer summary

Original wording in English

This service bulletin provides a service procedure to correct a customer concern of Power Liftgate Stops When Opening and/or Will Not Close from Open Position DTC B153F Sets.

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.
