Could you have done this with the kick panels under the dash off? You may have strained the air bag disconnect cable with your feet or the pedals.
I mention this because my Dad had done some work on our Caddy and left the panels off, and we wound up completely disconnecting the cable.
I fixed it by putting in a new connector on one end, as the wires had broken right at the safety plug for disconnecting the airbag while working in that area of the car(and I would like to punch the genius at GM who decided that they would have
a bunch of randomly shaped connectors for the air-bag disconnect plugs [both the inner part and the outer part] so you have to be really careful
when you do this to find the right shape connector).
I was hoping for an answer because my '03 Deville did the same thing. I put it to the floor for a couple seconds and check engine and air bag lights came one. I haven't had time to look at it yet but an easy fix would be nice.
The light had been staying out for a day or so, last night it came on when I went out. Then few hours later stayed out for drive back, ugh going to be fun for someone to hunt the fault if it happens to be functional at the time.
Is there anything special to do when unplugging and plugging back in the yellow connectors. My code is the b0044 Left Front/Driver Frontal Deployment Loop Circuit is there a more likely connector with this one. The results I saw on a Google search were all to or mentioning avalanche, escalade etc...
