Abstract
A method and system for diagnosing a fault condition in common connected squib loops is disclosed. A current source supplies current to the feed terminal for the first squib loop and current is returned through the feed terminal for the second squib loop. The voltage is measured between the feed terminal for the first squib loop and the feed terminal for the second squib loop.
