Airbag Gremlin
 

Airbag light came on for the passenger rear curtain while I was driving. It was subsequently cleared by the Indy. It came back a few days later.

What would be the best course of action to diagnosing if it's a bad airbag or a wiring issue.

Having difficulty pulling up a wiring diagram, so if someone could help I would appreciate it. Would any of the wiring be at risk of corrosion?

I guess the other option is to find one on ebay and swap it...$50 plus my time pulling down the headliner.

You can code the rear curtain airbag off, mine is currently coded to be off.

Update

I finally put the 1.4 scanner tool on it and I'm getting the Heard airbag, rear right, resistance too high.

I'm really not interested in turning the airbag off through coding as I won't be keeping the car, my original question still stands about corrosion points that I can look at or if i'll need to drop the headliner.

If I take it to the dealership, I'm going to drop the headliner so they can't charge me taking it down, putting it up.
