That shift is being driven by the rise of the software-defined vehicle , intelligent vehicle diagnostic systems, scalable over the air updates , and connected architectures powered by automotive Ethernet . Vehicles are starting to diagnose themselves Modern connected vehicles continuously monitor: ● ECU communication ● ...
