Abstract:
A method of measuring squib loop resistance including non-linear elements in a restraint control module is disclosed by the present invention. The squib loop resistance is comprised of both linear and non-linear elements. The non-linear elements are linearized into resistive components about the bias points used to make the squib loop resistance measurement. The calculation of the linear squib loop resistance is provided by comparing the complete squib loop resistance and the linearized value of the non-linear elements.
