A high-voltage interlock system includes a first module including a contactor and a shunt connection, and a second module, having first and second circuits, coupled with the first module via first and second wires. The second module, in response to impedance of the shunt connection exceeding a threshold, inhibits a signal to engage the contactor. The impedance is measured across the first and second wires while the first wire is multiplexed with low-voltage power to energize a coil of the contactor, and the second circuit is multiplexed with the signal to engage the contactor.
