Service bulletin N202310850 01

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

Customer Satisfaction Program (Revised Correction, Service Procedure and Warranty Information). In certain vehicles, driver movement can disrupt the electrical connection to the seat-mounted inboard airbag system. This airbag system is supplemental and not required equipment under applicable Federal Motor Vehicle Safety Standards. If this occurs, the vehicle?s driver information center will display a ?Service Restraints System? message to the driver before resistance at the connection will prevent the deployment of the airbag. Dealers are to verify the DTC B14DC is present and replace the affected driver inboard side seat wiring harness connector assembly as necessary.
