摘要： PROBLEM TO BE SOLVED: To provide a failure diagnosis system capable of diagnosing a failure by a diagnosis device for a node in a sleep state in a selective wake-up mode.SOLUTION: A diagnosis assist ECU determines whether or not a frame received from the diagnosis device is a diagnosis frame (S100). When it is the diagnosis frame (S100: YES), a diagnosis object ECU is searched (S110). Then, a starting ID of the diagnosis object ECU is set up in a wake-up frame (S120) and the wake-up frame is transmitted to a bus communication path (S130). The sleeping ECU receives the wake-up frame by a transceiver and compares the starting ID set up in the wake-up frame with an own starting ID. When they match, the transceiver instructs a power circuit to supply power to a CPU.

摘要： PROBLEM TO BE SOLVED: To achieve a shift of a slave node to an individually instructed wakeup state, using a general-purpose transceiver.SOLUTION: When a startup ID storage processing unit in a microcomputer determines the start of completion processing on the basis of a shift instruction to the sleep state etc. (S100: YES), a startup ID for determining the shift instruction to the wakeup state is stored into a startup ID retention memory in a transceiver (S110). When the startup ID is stored in the startup ID retention memory, a reception data comparison circuit in the transceiver compares a reception data with the startup ID, and in the case of coincidence, outputs a reception permission signal to permit a receiver circuit to receive, and also outputs a power supply signal to allow a power supply to supply power. In short, by the storage of the startup ID into an individually designed microcomputer, the startup ID is stored into the startup ID retention memory of the transceiver at a predetermined timing.
