If you have a Toyota Tundra with the warning message on the instrument cluster that reads "Brake Controller Error if Towing, come to a safe stop with manual controls. Contact Dealer" then you will want to start by check for codes. You may come up with codes C0210 and U0129. If this is the case, then its likely that one of the rear ABS sensor wires is the culprit.
