A microprocessor system for a steer-by-wire steering apparatus for a vehicle includes a hand wheel actuator controller 103 with first and second microprocessors 107, 108 controlling a hand wheel actuator 101, a front axle actuator controller 106 with first and second microprocessors 109, 110 controlling a front axle actuator 104 and first and second private buses 111, 112 connecting pairs 107, 109 and 108, 110 of microprocessors of the actuator controllers 103, 106. Each private bus 111, 112 has physical layers capable of transmitting data with two different first and second data layer formats. The system has a first state in which first private bus 111 uses the first data layer format and second private bus 112 uses the second data layer format, and a second, fault, state where either or both private buses 111, 112 change data layer format if a fault is detected on either of them. An actuator controller and a method are also provided.
