I recently had a sat radio installed and the installer was poking in behind the existing radio and the passenger air bag light to install it.

Now, the dashboard air bag warning light comes on sometimes, and blinks the code 27 which indicates " Passenger Air bag Deactivation Lamp inoperative" or "shorted to ground".

Because this only happens once in a while, I suspect the installer knock the lamp loose a bit, or knocked a wire loose.

Does this sound right to you guys?

I'm also wondering if the installer took power for the sat radio, from the air bag light, could this cause the problem?

Thanks

 

check where he was working to make sure he didnt knick or scrape your light wire somewhere that it can ground out every now and then

 

Yes, that makes sense too, thanks.. I'll do that and report back here...

Thanks
