A vehicle power system may include a signal driver system electrically connected with a signal receiver system, and a traction battery electrically connected with contactors responsive to the signal receiver system. The electrical connections may be routed through a common interface. A voltage associated with a control signal commanding the signal receiver system to cause the contactors to close and driven into the electrical connection between the signal driver and signal receiver systems by the signal driver system may indicate whether the electrical connection between the traction battery and contactors at the common interface is faulty.
