Personally I don't care if you help or not... There are many faults that can develop in the airbag circuits on these cars and not every fault can be attributed to the B1161 codes (or anti submarine rams.)
Funny that Nissan have no idea what those codes mean, let alone knowing how to repair them. I have been trying to fix my particular airbag codes for 4 years so far, as have many others, and buying new seats from Nissan obviously isn't an option for most of us. If there was a simple fix to drop a resistor or diode over the faulty unit, at least the other airbags would deploy in an accident... Alas, still no information.
