Thanks, that works perfectly. I've had to do it twice now on my 2009. I did it right after I bought it, that worked for months. Then recently, I pulled a relay out in the fusebox under the hood for an unrelated reason, and after I put the relay back in, the stupid seat belt alarm reset itself and started up again, so I had to search and find this thread so that I could turn it off again. So I printed a copy of the procedure and stuck it in my Owner's Manual in the runner, in case it ever happens again -- I recommend everyone do that.
