Abstract: A vehicle includes a controller having a microcontroller and a monitoring processor. The controller includes a bus transceiver for communicating on an external communication bus. The controller is configured such that each of the microcontroller and the monitoring processor can output a transmit data signal to the bus transceiver. The source of the transmit data signal is selected as the output of the monitoring processor responsive to evaluating the microcontroller as being inoperative.

Abstract: A vehicle includes a first controller having a processor and a monitoring unit. The monitoring unit generates a question and transfers the question to the processor via a first bus. The processor generates an answer corresponding to the question and transfers the answer to the monitoring unit via the first bus. The processor transfers the question and the answer via a second bus. The vehicle includes a second controller coupled to the second bus and programmed to transition to a reduced performance mode responsive to the answer being different than an expected answer to the question.
