Abstract
The number of ports of a microcomputer is increased to detect an abnormality of the power supply line in a case where a power supply line to a load circuit is increased in number by two or more systems. A first resistor Rand a second resistor Rare commonly connected to one end of a third resistor R. The other end of the third resistor Ris connected to a monitor port of the microcomputerand is grounded through a fourth resistor R. The microcomputerdetermines a value of a monitor voltage input to the monitor port to determine an abnormality of a first power supply line Land a second power supply line L. Specifically, it is determined whether the first power supply line Land the second power supply line Lare short-circuited to a ground side, or a voltage is not supplied to the first power supply line Land the second power supply line Ldue to an open circuit.
