I don't know if this has been shared before, but I wanted to share this link with everybody just in case it has not been put out here on the forums. I know that most of this information is probably engraved in most of us, but there are some good descriptions of how some of the systems work in our cars and quite honestly, I learned a LOT from reading through this.

If it has been posted already, than feel free to delete this post. I searched but I didn't find anything like it. Thanks to everyone at north Miami Lexus for writing up this page. In NO way do I take credit for ANY of this page... I just so happened to find it after looking for answers regarding the electronic brakes in my GS460

Enjoy!
