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.

Vehicle high-voltage systems isolation testing

A vehicle controller of a vehicle may set a message acceptance type and a time window for response according to a type of association procedure message received from a requester, provide the association procedure message to electric vehicle supply equipment, and return a received response message to the requester when the response message is of the acceptance type and received within the time window, and otherwise reject the response message.
