An in-vehicle control device connected to an in-vehicle LAN system conforming to a CAN protocol, when an output signal output from a second controller maintains a dominant level for a predetermined time, determines that there is an abnormality in the output signal output from the second controller, and converts the output signal output to a selection section from the second controller into a signal of a recessive level.
