service air bag message comes up and air bag symbol is illuminated. had it scanned, came up with B0090 active siwtch voltage out of range. happened right after i had an alarm and remote starter installed. did lots of searching and seems like what could of happened is the wiring might have been disconnected without power being disconnected first. just wondering if anyone else has been through this. a few had found changing the switch/sensor behind the dash fixes the problem. does anyone know the part number for this?
