Abstract
A method and system for diagnosing the squib leakage resistance through a restraint control module is disclosed in the present application. The newly proposed system and method provides a highly accurate measurement by minimizing/eliminating the effect of the unknown source voltage effects. The concept utilizes the squib leakage resistance diagnostic resources with a multi-step measurement approach, for example utilizing measurements of two currents and/or two voltages.
