What does error code U0428 mean?

The trouble code U0428 is related to a communication problem. You get this error code when the steering angle sensor module gets invalid data. A controller Area Network or CAN bus system mainly interconnects automotive devices without any host computer. This bus system operates information, exchanging commands with other devices. These devices are programmed with information about what messages are mandatory to be traded on these serial data circuits. With the help of this serial data communication network, some devices are constantly receiving information from other devices. The invalid data of DTC or Diagnostic trouble code will be fixed when a receiving device detects a discrepancy in the information it gets from the Steering Angle Sensor Module, causing its integrity to be questioned.steering angle sensor repair
