U0454Invalid Data Received From Side Restraints Control Module - Right

U0454 means the vehicle's main restraint control module has stopped receiving valid data from the right-side restraints control module over the controller area network (CAN) bus. The computer detects a communication fault, not a crash sensor failure, so the airbag warning lamp is typically illuminated and the right-side airbags and pretensioners may be disabled.
