THANK YOU!
I found the following information while I was "up all night". I think I will get down to the control unit and first try unplug/plug in everything as long as I have to get to it to read the numbers.
I am taking it that you did not have to code the control unit to the car, I read stuff about the airbag control module has to be coded to the VIN #?


Airbag Ignition Circuit - Drivers Side - Defective
This fault is often stored during repair of other components (removal of steering wheel or instrument cluster). Disconnect connector from generator module. Check wires from control unit pin 10 to contact ring pin 1 and pin 11 to contact ring pin 2 for continuity. Measure resistance of squib (detonator) at generator module (1.8 - 5.6 ohms). Replace if out of range. Check steering-wheel contact ring. Connect generator module and measure resistance at control-unit plug between pin 10 and pin 11 (1.8 - 5.6 ohms). Replace steering-wheel contact ring. If the fault code recurs, replace control unit.
