My 2000 Saturn SL2 ABS and Brake light come on when I hit about 25 mph and before the abs light comes on when I hit the brakes the ABS engage like I‘m on ice. I changed both ABS sensors and checked the fuse, could it be the brake master cylinder? (the brake pedal is kind of spongy) I went to Auto Zone and they said their scanner only does check engine lights.
I had the same problem with my Ford F150 truck, ABS light came on and brakes would pump like on ice, but was on dry pavement . Problem was the ABS computer chip needed to be reprogramed, COST $380.00 I told them to disconect ABS chip,the brakes work like the old days. you have to pump on ice but I saved 380.00
Check your brake fluid level, if that is low then check for leaks in the system. Could be brake calipers, wheel cylinder steel lines, rubber hoses, master cylinder. If the fluid level is ok and you find no leaks dont spend anymore money till you get the ABS Module scanned and you know what codes are in it that will help you diagnose the problem.
Sounds like a failed ABS module. You need a code reader not the one chinazone has to read the ABS system. Or you can unplug the module and just live with out anti lock brakes. Light will remain lit. The other option would be to get a module from pick a part.
