Abstract:
1. A simulated airbag squib comprising: a first airbag crash controller squib initiation line; a second airbag crash controller squib initiation line; a selected resistive load connected across the first line and the second line so as to simulate an airbag squib; an electrical switch connected between the selected resistive load and said second line, so that when the switch is open a resistance between the first line and the second line due to said selected resistive load is substantially greater than a nominal resistance of the airbag squib; a fault indicating circuit having a first isolator which has an input side and an output side, the fault indicating circuit having a current loop which includes the output side of the first isolator and supplies voltage from the fault indicating circuit to the electronic switch, and the fault indicating circuit having a current pathway between a voltage source and a ground which includes the input side of the first isolator and so the current pathway is electrically isolated from the current loop; a control signal source in current controlling relation to the current path; and a second circuit having a second isolator which has an input side and an output side, wherein the second isolator input side is connected in parallel to the selected resistive load and the second isolator output side is connected to a signal output line.
