Title: ELECTRONIC CONTROL DEVICE
Abstract:
To provide an in-vehicle control device enabling to improve reliability of diagnosis on a path between a microcomputer and a monitoring device. In the cases where an internal error occurred during a period when a diagnosis control signal 11 is high (H), an internal error abnormality detection unit 17a sets a reset generation request signal 3 to be H, and inputs the signal to a monitoring module 2 via a path P1a, and during a period when the diagnosis control signal 11 is low (L), the internal error abnormality detection unit sets the reset generation request signal 3 to be H, and inputs the signal to the monitoring module 2 via the path P1a for the purpose of testing. After the internal error abnormality detection unit 17a sets the reset generation request signal 3 to be H, and inputted the signal to the monitoring module 2, a diagnosis unit 21 diagnoses the path P1a on the basis of the signal level of a path P2a branched from the path P1a.
