Service bulletin 122-V9W9U-09

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.

NHTSA's summary

Information: Due to a software error, there is a possibility that the enhanced seat belt diagnostic function may not detect the driver's correctly fastened seat belt on the affected vehicles. If this happens, the warning message "Driver seat belt not fastened, Fasten seat belt" will be displayed in the instrument cluster. Remedial Action: Re-program the airbag control unit using the PIWIS Tester with software version 35.650.010 (or higher) installed.
