Change the cabin air filter this morning on my wife's 2005 XC90 V8. She turned on the ignition and the error panel now says SRS Air bag failure - Service immediately and the red warning light on the dash is illuminated along with the rear view mirror saying the Passenger Air bag is off. All I did was change the cabin air filter - now I get all this crap. Any suggestions on what could have happened or erasing the error code with out a code reader?

 

Now the error code has changed to Passenger Side Air Bag Off - Service Urgent.

Any idea on what may have set this off?

 

You need to have someone that can read the SRS codes read and try to clear it.

 

That's kind of what I figured. I ordered a code reader yesterday and will do just that when it arrives.

 

I got a code reader on the car. Says there are no codes to read. Still get a Passenger Side Air Bag Off - Service Urgent message on the dash. The red warning light for the air bag and the Passenger Air Bag off on the rear view mirror. We don't have a Volvo Dealer within 300 miles of my place and I don't really want to pay them to work on it. Anyone run into this issue and have a solution?

 

That reader must not read SRS codes.
I wish you had asked before ordering the one you did. This one is supposed to read and clear SRS codes. http://www.alpha-bid.com/product230.html
