The abs module on those is a known problem. I fix them all the time. There are usually 8 pins on the circuit board I resolder after opening the unit. Its not easy to get the case open because its glued shut. Removal of the unit itself can also be tough. The ones under the hood arent bad but most of the full size stuff I do its under the cab on the left frame rail facing up. Most shops want a lot of money to replace the module. I fix them in about two to three hours with nothing but a torx bit, a razor knife and a soldering iron. The pins that crack the solder joints are for the main power plug into the unit. Look it up on youtube its a super common fix.
