Control processor unit (CPU) error detection by another CPU via communication bus
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.
