I have a 2002 Buick Rendezvous CX (2wd no traction control). My ABS is throwing a C0040 and C0035 code. After reading some info it seems to most likely be a wiring issue. Would a wiring issue also cause brake performance issues? At times when I brake there is a slight “pulsating” feeling in the pedal accompanied by a noise like I’m on gravel (not the bad pads/rotors noise). I can also here a very fast (but faint) clicking noise when I brake at low speeds.
