I started to have a problem with my car after I tried to jump my battery with acid leaking. Car sizzled. When I put in a new battery the nav went dead and the ABS Brake traction lights vsc off all came on. I fixed the nav by identifying a bad fuse. The lights still remained on. I took the car to a brake place reluctantly and I walked out getting 4 sets of pads and two new calipers, which I feel in hindsight I didn't need all of it. My lights are still on. The dealer says I need a new ABS control module. Here are the error codes. CO278, CO1223, UOO73, UO124, UO124, UO126. I'm looking around to see if I can get the part on a 3rd party site. Can anyone help me here with these codes to verify? Also, is there any fuse worth checking first for the ABS? Where would it be located if there is. I am new to this forum. I appreciate any help.

 

C01223- left rear wheel speed sensor...I would check wiring to it and fuses associated and or replace it...this will cause ABS light. The U0124 and126 deal with Acceleration and steering modules which again may be caused by the electrical issue you had with the bad battery and jump start ...check fuse's and relays.

 

Are you sure the leaking battery acid didn't damage the engine room harness? If it all looks good, I'd clear the codes and see what comes back. Low voltage can do quirky things.
