Fiat Grande Punto 2007 AirBag Issue

Hello!

I have problem with Grande Punto, car had a crash and airbags are replaced and airbag control unit was reset.
I have managed to eliminate 5 DTC's, but there are 3 more that i can't find...

B0123 Abdominal pretensioner resistance too high driver side
B0124 Abdominal pretensioner resistance too high passenger side
B0103 1st level, driver's airbag resistance

Can someone help me about this?

Thanks!
