First, make sure the brake fluid isn't low. If it is, top it off with the correct fluid.
If that isn't the case, most often these lights are on as a result of a bad wheel speed sensor. If you have the system scanned, it will identify it that is the issue and which wheel is the cause. Otherwise, we will need to check one wheel at a time using a multi meter. It really isn't hard to do. Here is a link that explains how it is done. However, before doing this, make sure the ABS fuse isn't blown. There are three fuses I need you to check first. They are located in the under hood fuse / relay box. See pic 1.
Here are a few links you may find helpful:
If fuses are good, take a look through these links:
Let me know if you have questions. I did include a general wheel speed sensor replacement link. However, I need to know if the engine size and if the vehicle is AWD or not to provide specific replacement procedures.
Please feel free to let me know if you have other questions.
