A couple months ago I installed a new head unit. I had to unplug the airbag indicator to remove the center console. I had it in and out a dozen times over a few days while I tried to figure out the steering wheel control unit. After I figured everything else out with unplugging and plugging in the air bag indicator successfully with no issues, I now have the airbag light flashing code 122. one long flash and 2 short flashes. Ive tried resetting it using the ignition on/off method a few times with no success and checked any connections that I may have disturbed while replacing the head unit. Anything else I should be checking for before I have it in to a mechanic?
