Air Bag light on by mistake

[zman0803]

Well folks, I needed to put in a new left rear window regulator. It went well thanks to the DIY that I read here. (Thank You to all those involved)

Except one thing. My brother is a mechanic that has worked at a Toyota dealership for many years and has great knowledge about most cars. I told him to make sure the battery was disconnected before he unplugged the bag. He did unplug the battery before he unplugged the bag, but when he reconnected the power to move the window up and down, yep, he forgot to plug in the airbag. So now the light is on.

Now, I guess I have to take it to the dealer now? What is the going rate to have it cleared?

I'm really bummed because I saved money having him do it but his little mistake I think might have just cost me another $60-$100? Does that sound right?
