In case someone didn't know this, some modules can be repaired. There are a bunch of companies out there that will repair your existing part if you ship it to them. It's usually on a couple days of down time and new modules are usually a fortune. I recently did this on a Highlander climate control unit. Worked out great.
Another option is buying a part used and programming it or paying someone to do it. Since these parts are so dang exoent new, it's nice to have a few options that usually work.
BBA Reman are pretty reliable they operate in Europe and North America -- the section on their website listing common failures is also cool.
