2010 mitsubishi lancer DE has code C2104 how do I fix it? I scanned it at Autozone, and that's what showed up. is it a bad speed sensor? I hope, it's not the ABS module-to damn expensive-and shops have outrageous prices.
Yes it reads all the major systems. It’s supposed to have two way interaction to actually bleed different systems within the brakes and AYC/ACD but I’m not a pro at using it. But it definitely will read all the major systems to help narrow down a problem.
