SYSTEM FOR DETECTING A FAULTY ECU ON A VEHICLE NETWORK AND A METHOD THEREOF

A system and method for detecting a faulty electronic control unit (ECU) on a vehicle network are disclosed. The system includes a monitoring controller configured to detect an identification (ID) of a controller area network (CAN) message first transmitted on a vehicle network and transmit the ID of the CAN message to a gateway controller. The gateway controller performs a wake-up when a vehicle engine is turned off, enables the monitoring controller and detects an ECU corresponding to the ID of the CAN message as the faulty ECU.
