ABSTRACT:
An engine management system for a vehicle includes engine and transmission control modules that are connected to a serial vehicle data bus. A dedicated serial data bus is connected to the transmission control module and the engine control module. The engine and the transmission control modules perform processor validity and integrity checks over the dedicated data bus. In an alternate powertrain management system, engine and transmission control modules are connected to a serial vehicle data bus.
