Claims
- 1. A control module for a vehicle having at least one device containing a squib and at least one device containing a replacement resistor, the control module comprising:a circuit having a plurality of loops, wherein at least one loop is a squib loop containing the squib; and a multiplexer connected to at least one of said plurality of loops, wherein the multiplexer forms at least one replacement resistor loop containing the replacement resistor.
- 2. The control module of claim 1, wherein the vehicle contains a plurality of squibs and a plurality of replacement resistors, and wherein the ASIC has a plurality of squib loops, each squib loop containing one of said plurality of squibs.
- 3. The control module of claim 2, wherein the multiplexer forms a plurality of replacement resistor loops, each replacement resistor loop containing one of said plurality of replacement resistors.
- 4. The control module of claim 1, further comprising a microcontroller that controls at least one of the circuit and the multiplexer.
- 5. A control module for a vehicle having a first plurality of devices each containing a squib and a second plurality of devices each containing a replacement resistor, the control module comprising:an application specific integrated circuit (ASIC) having a plurality of loops, wherein at least one loop is a squib loop containing the squib in one of said first plurality of devices; a multiplexer connected to at least one of said plurality of loops, wherein the multiplexer forms a plurality of replacement resistor loops that each containing the replacement resistor in one of said second plurality of devices; and a microcontroller that controls operation at least one of the ASIC and the multiplexer.
- 6. The control module of claim 5, wherein the microcontroller controls operation of both the ASIC and the multiplexer.
- 7. A method of diagnosing a first plurality of vehicle devices each containing a squib and a second plurality of vehicle devices each containing a replacement resistor, the method of comprising:connecting each squib in said first plurality of vehicle devices to a circuit to form a plurality of squib loops; connecting at least one of the loops in the circuit to a multiplexer; and connecting each replacement resistor to the multiplexer to form a plurality of replacement resistor loops; and monitoring the plurality of squib loops and the plurality of replacement resistor loops.
