ok so my abs light is on can i get some possible reasons of why and how to fix it.

 

Check the brake fluid and fuse first,these are the cheap things.The system should store codes that can be read by a scanner,Advance and Autozone will read your codes free of charge.Make sure the speed sensors and trigger wheels are free of dirt and have no broken parts.Follow the wires back to their connections and make sure they are tight and no corrosion inside.Make sure the module wires are tight and not corroded also.The module is located in the right front corner of the engine compartment.
