Fault Code B2290

Sure could use some help on this!
Got a 2008 Focus that was involved in a collision, all has been repaired and the new air bag control module installed but now have this code B2290 or Occupant Classification System module fault. I have tried to clear but still remains so I decided to exchange the seat with an identical seat with all matching part numbers on modules and harness and still it will not clear the B2290 code! What else will cause this? Will a module cause this? I should point out that the module was remanufactured but it tests OK with only the code.
Help would be great.
Thanks

I should add that the passenger side air bag (curtain) and the drivers seat pretensioner we the only components that were set and not knowing the the details of the accident would figure that the passenger pretensioner was not detonated so no passenger was present at time of accident. The seat that I tried as a replacement also came from a wrecker so was involved in a collision but all components of the seat are fine, is it possible that reprogramming of some sort is required?

Re: Fault Code B2290

The body shop that fixed your car should be responsible for fixing this problem. Can you still take it to them? Or was the accident a while ago?

Re: Fault Code B2290

No I am the shop fixing the car but have not run into this problem before so was looking for a little technical help. I am a bit remote and outside help is not readily accessible as far as diagnostics go. It may be as simple as a reflash at a dealer but really need to be sure before heading down that road!

Re: Fault Code B2290

Yes I had read this posting but thought it was still a bit cloudy on the details, I had the concern that because there was most likely no passenger in the car because the pretensioner is ok why would the components in the seat need to be replaced? The sensor the tech describes is an bag that is in the seat and measures weight to a sensor switch and I have a hard time believing this would be the problem being I have never run into this before. I don't know any of this for sure but really looking for a conclusive answer before I load the car and haul it miles away to a dealer.

Re: Fault Code B2290

Is there a occupant classification reset option on your scan tool?

Re: Fault Code B2290

I do have "delete"option on the scan tool. I cleared the crash data from SRS module. Replaced both side airbag and passenger airbag in the seat. after that deleted the codes and they dont show anymore. Still stuck with b2290. swapped seat with used one from the junk , tried to delete b2290 few times with no success. The seat had airbag intact-not deployed. Cant think of any reason why the occupational sensor/module will trow that error in first place. Ford states that whole bottom part of the seat has to be replaced with module+sensor factory installed for it to work. So replacing only bladder or module wont work . Any help will be appreciated as I cant pass smog check. Is the seat need to be programmed in any way after swap?

Re: Fault Code B2290

I also sent PM to OP but have no response yet. Google don't reveal anything either . Im open to solution which will deploy the airbag even if there is no passenger. Better then to have the airbag always off.

Re: Fault Code B2290

If you swapped the entire seat the new sensor needs calibrated. Possibly programmed.
