does anybody know what B1001 is, it says something about configuration error or something like that

 

am pretty sure it has something to do with airbag sensor. can anybody help?

 

option configuration error...have you replaced any airbag parts or BCM lately?

 

replaced the driverside and passenger side airbags and the module between the seats

 

Did you replace the SDM (between the seats) with a new one or a used one? It needs to be the same part number. I assume the airbag light is on? If so, try removing airbag fuse for a minute and reinstall. If that doesn't work, then the SDM i.d. does not match the i.d. for it that is stored in the Instrument cluster (IPC) and the IPC may need to be reprogrammed by a GM dealership with a Tech 2 diagnostic tool.
