Bulletin Summary
Region Email: The subject vehicles are voluntarily equipped with an event data recorder (EDR). The EDR only collects, stores, and allows retrieval of vehicle event data, including crash events. It does not control the operation of the vehicle or crash safety systems. Due to a software error in the air bag ECU where EDR data is stored, the EDR data for ?Frontal Airbag Deployment, Time to 1st Stage Deployment,? and ?Frontal Airbag Deployment Time to 2nd Stage Deployment,? will show the same value at the time an event is recorded. This software error has no effect on the actual air bag?s deployment times for both stages. Both air bags operate as designed.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
