Service bulletin PIC6025C

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

If there is a Diagnostic Trouble Code B305A stored history in the Body Control Module it may have been caused by a bound up steering wheel. Review the owner’s manual Starting the Vehicle Messages section with the customer.
