The invention provides a steering system with multiple controllers. A system includes: a steering system motor; a first ECU (Electronic Control Unit) and a second ECU (Electronic Control Unit), wherein the first ECU and the second ECU are respectively and electrically connected to the steering system motor; a communication line connecting the first ECU and the second ECU in a direct communication manner; and a gateway module that communicatively connects the first ECU to a CAN bus and that communicatively connects the second ECU to the CAN bus. The first ECU is programmed to transmit a fault code to the second ECU via the communication line and via the gateway module upon detection of a fault. The second ECU is programmed to transmit a fault code to the first ECU via the communication line and via the gateway module upon detection of a fault.
