Re: Code B0081 - service air bag lite on
Right, the 03 sub code is for voltage below threshold, weak battery, parasitic draw pulling the battery down, something, can't be hard to figure out. The B0081 71 is the one you're interested in. There is very likely a PPS code that has to be flashed and then you'll know what is wrong. I have a Cobalt in my bay now with that code and the PPS had a code in it for the seat belt tension sensor, so as soon as I fix the tension sensor, the PPS code will clear and then so will the B0081 71 code. You need to know what the PPS code is before going further.
