Abstract
A system, apparatus, and method for testing a squib circuit. An electrical signature of the squib circuit is monitored when a test switch in the squib circuit is activated. The electrical signature of the squib circuit is based on characterizing resistors electrically connected to squibs in the squib circuit in which each characterizing resistor in the characterizing resistors has a resistance value. A health of each squib in the squib circuit is determined based on the electrical signature of the squib circuit.
