ABSTRACT:
A test circuit for an airbag restraint system is disclosed and provides an accurate determination of the operativeness of a storage capacitor and calculates the resistance of inertia switch resistors. The capacitor is tested by discharging and charging the capacitor. The values of the inertia switch resistors are determined by switching known resistive values in parallel with the inertia switch resistors. Based on the monitored voltage values during the switching, resistance values are calculated.
