Patent abstract
A disconnection detection device for an in-vehicle device having a load circuit, is provided with a second wire harness which is arranged along at least a part of the first wire harness, a current circuit which supplies a current for disconnection detection to the second wire harness, and a disconnection determination circuit which monitors an output voltage of the current circuit so as to determine presence or absence of disconnection of the second wire harness. Disconnection of the second wire harness is detected as the disconnection of the first wire harness based on disconnection determination of the disconnection determination circuit.
