Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electronic control device capable of checking each part of an input signal processing circuit, etc. for any error without requiring an additional path or timer. SOLUTION: An error checking signal is input to the input signal processing circuit 21 or a selector 22 based on a command to shift to an error check mode from a CPU3, and output signals OUT0 to OUT3 at that time are input to the CPU3 to conduct error check. This allows error check of a capturing function of the CPU3, in addition to the input signal processing circuitry 21, but also error check of each element and wiring of a path for transmitting a signal indicating a wheel speed to the CPU3.
