Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The B1406 refers to the passenger presence detector in the cushion of the passenger seat. What happens is that someone kneels on the seat and the sensor is a sheet of mylar that cracks when knelt on.
To replace the sensor is about $300 so bargain accordingly.
