摘要： A circuit abnormality diagnosis device includes a calculation unit, an inspection power supply, a rectifier element, overcurrent preventing resistors and a voltage amplification unit, a voltage reading unit, and a light emitting unit. It performs a circuit abnormality diagnosis at a preset time (including the time of initial mounting) or every predetermined time. The device determines that a case where a voltage value is within a range of a first voltage value V1 or more and a second voltage value V2 or less, which is set in advance as a range of voltage values indicating that a circuit is normal, is a normal state, a case where the voltage value is less than the voltage value V1 is a short-circuit state in which the circuit is short-circuited, and a case where the voltage value is higher than the voltage value V2 is a disconnection state which the circuit is disconnected.
