A distributed control system for a vehicle includes one or more processors and one or more memory devices storing computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations. The operations comprise obtaining an instance of shared data for a control system of the vehicle from each of at least three separate nodes of the distributed control system. The shared data may include configuration or health data for the control system or the vehicle itself. The operations include comparing the at least three instances of shared data; detecting a shared data inconsistency amongst the at least three instances; and generating a control action associated with resolving the shared data inconsistency.
