Code B2064 Description

The Seat Belt Control ECU is connected to the Main Body ECU using CAN communication. The Seat Belt Control ECU receives vehicle model information from the main body ECU and determines whether the seat belt buckle switch information from the center airbag sensor assembly is for the driver seat or the passenger seat. The Diagnostic Trouble Code (DTC) B2064 is stored when the CAN communication frame with the main body ECU is normal and communication is available, but the steering wheel position information is not set or varies.
