Please help me with advice on codes C1311 & B1650 on my Prius C.

Hi to all! My another project car throw me some things to get resolved. I got a real nice Prius c with only 8k miles on it. It had easy damage on the drivers side, however roof and seat bag deployed. Car has been fixed up completely, except that it has few lights on my dash. I got Airbag light! All deployed airbags have been replaced along with the drivers seat belt, srs module was fixed (reprogrammed). So I see the code C1311 - Brake inhibit Relay Circuit/open circuit. When i go and read live data it says this :
1. occupancy detect 1 - fault detected
2. D-seat buckle SW - uninstalled
3. P-seat buckle SW - uninstalled.

Next, i have all light that belong to brake system, like 4 or 5 of them. Code that i have is B1650 - Ocupant Classification System.

Any idea what could be wrong with it?????

 

its Launch x431

 

just a little update, the code B1650 was causing that one of the ABS Fuses was bad. As soon as I replaced it, all brake lights dissipated. Now i believe I have to recalibrate my airbag seat sensors. Will see if its gonna help.
