Abstract

An interlock diagnosing system and method for a high voltage device includes: a detection circuit between a transmitter providing a voltage and a receiver receiving the voltage provided by the transmitter; a plurality of resistors connected in parallel to the detection circuit via a respective plurality of connectors engaged between the plurality of resistors and the detection circuit; and a detector detecting engaged states of the plurality of connectors based on at least one of the voltage provided by the transmitter or the voltage received by the receiver, or both. The detector calculates a resistance value of the detection circuit based on the voltage provided by the transmitter and the voltage received by the receiver and detects the engaged states of the plurality of connectors based on the calculated resistance value. Each resistor has a different resistance value from each other. The detector detects a disengaged connector among the plurality of connectors based on the calculated resistance value.
