Question Help!!! Dash abs light stays on!

My ABS light on my dash comes on frequently. Mostly when it's low on fluid cuz I know I have a leak. But sometimes been when it's full it'll come on. My brakes act fine and the pedal is fine. It has a leak up towards the master cylinder. I painted my whole under carriage (axles, suspension, steering... The works) and noticed it when the paint on my driver side leaf spring started bubbling and pealing off. Right then I knew it was brake fluid cuz the paint and the location. The problem is though all the fittings are tight and don't appear to be leaking but this wire connector going to the master cylinder has fluid all over it. But it's just an electrical fitting not a fluid fitting!!! What's my problem!?!?!!?! My email is [email protected] and my cell is 509-350-9098. If anybody knows please help ASAP! I take care of my paralyzed amputee Retired U.S.M.C. Vietnam Veteran dad and go to doctors appointments very often and need my vehicle mobile at all times in case an emergency but am also unemployed at the moment due the time needed to take care of his needs and am. Dry mechanically inclined but that's mostly with older vehicles (muscles cars and 70's Ford 4x4's and Jeeps) I hate working on the newer stuff but love diesels and won't ever go without one and am learning a lot as time progresses so please throw whatever at me that you have. Thank you, God bless and Support America!!!

Is the switch mounted on the master cylinder? If so, there is a factory recall on the master cylinder cruise control pressure switch. This switch turns off the cruise control when the brakes are used. The dealer replaces it for free with an updated one.

Re: Help!!! Dash abs light stays on!

Could also be your ABS sensors (3). Most likely its the back one on top of the rear diff. Clean them up and re-install. see if that works. If not i think there is a way to test them but youd have to do a search on that subject. If their bad replace them. Other 2 are on each front wheel behind the brake guards on top of hubs. good luck.

If your hubs are shot the play can trip a light.
jack up the front tires one side at a time and see if there is play.
