The seat belt control ECU receives vehicle model information from the network gateway ECU and determines whether the seat belt buckle switch information from the airbag sensor assembly center is for the driver seat or the passenger seat. DTC B2064 is output when CAN communication with the network gateway ECU is normal and when communication is available, but the steering wheel position information is not set or varies.
