Thanks for the link bar. Seems they are quite expensive.
Would someone like me with very limited vehicle mechanical experience be able to read and understand the information provided, then actually do something with it?
Looks like folks in this forum are using them for all sorts of things, including turning off air bag lights.
If this tool would really help me, and would be a benefit, I definetly need to purchase one. Seems there are a few for sale occasionally, but snatched up pretty quickly.
