SRS Battery problems
My battery has been dying the colder it gets this year. I have had to jump it twice. The battery is very old and I do not drive far but when I do I put a decent load on the alternator so im not surprised the battery has declined this winter.
Well last night it died I had to jump it to get home when I did so one of my tail light blew out. No big deal but maybe related.
This morning It was dead not a big deal I was expecting it to happen, I replaced it without much hassle. Then when I turned the car on with the new battery installed my SRS warning lamp stayed on and has done so all day.
Should I hook up a scan tool to find out where the problem is or did I blow a fuse while replacing the battery? Maybe the srs computer needs to be reset when the electrical connection is removed?
What do you guys think?
Thanks

You may have to go to someone with a professional scanner tool. The SRS usually cannot be reset by a common OBD II tool. Try disconnecting the battery again for 30 seconds but I would not get your hopes up.

The dealer I called recommended that I turn the wheel from lock to lock to see if the clock spring would send a signal or not. Could A blow fuse trigger the srs light?

I disconnected the battery for awhile and tried the wheel thing 
No luck. I will bring it to school monday and hook up a scan tool. We have like ten but im sure none of them will work but ill try.
what is the most common cause for srs light to come on?
