The disclosure relates to a transceiver device, an electronic control unit and an associated method. The transceiver device is suitable for communicating between one or more network protocol controllers and a network bus and comprises: first interface circuitry configured to communicate with the one or more network protocol controllers; second interface circuitry configured to communicate with the one or more network protocol controllers; and selector circuitry configured to switch communication with the one or more network protocol controllers from the first interface circuitry to the second interface circuitry in response to a communication error in data carried on the first interface circuitry.
