I have an 06 ss/sc 2.0 LSJ. Ever since I got the car the abs light has been intermittent. Usually on when it's really cold outside. Recently it has been in constantly and so I finally scanned it. The code was U2108-00 ( Lost Communications with anti-lock brake system. ) at first I though it was the wheel speed sensor but then once I realized it lost all communications, it must be something more. Id really rather not replace the whole abs module because they're a little pricey, but if it comes to it whatever. Just looking for ideas on where to begin the fix. What to look for, etc. anything will help guys. Thanks for reading! Hopefully someone can help out!

 

Check all your connectors for corrosion, add di-electric grease.
