I'm reaching the point where I'm about to drop a few hundred dollars on a guessing game and I'm not a very gambling man. Whenever I stop on a low traction surface (ice, snow, even gravel if I stop hard enough), the abs/traction control lights come on and abs stops working entirely. This will also happen if my tires start spinning, which on a vehicle that barely passes as 4wd without that system is very annoying and has gotten me stuck more than once. I have replaced all 4 wheel speed sensors on a whim, didn't help. The code it throws is C2200 "Internal ABS Module Error". I've also replaced all of the brake pads on that same whim, no change. There is also a grinding noise when the abs kicks in. My next stop is replacing the abs module entirely, but given that the part seems to be impossible to get new I don't really want to do that. However, if I have too, should I save some money and replace just the pump or the module, or should I replace both. Also, do I have to get the module flashed at a dealer for it to work?
TL;DR: ABS lights when I loose traction, C2200 code, sensors and brake pads replaced, if I buy a new module do I have to get the dealer to flash it?
