An isolation test system for a vehicle includes a communication interface, a current sensor, a plurality of impedances and a controller. The controller is programmed to electrically connect a selected one of the impedances between a traction battery of the vehicle and a low voltage subsystem of the vehicle. The connection creates a leakage path between the traction battery and the subsystem. The controller is further programmed to output a diagnostic status based on a current associated with the leakage path and a signal received via a communication interface indicative of an isolation fault between the battery and subsystem.
