Abs

What is your question? If you are asking about why the dash light has come on, it is because a fault has been detected in your ABS system. Brakes may still seem to work fine but the ABS feature is not functioning properly. Have it checked out.

ABS light came on ('97 Ford Explorer XLT 4wd) 18 months ago. Took to my mechanic (not a dealer, can't afford them) asking should I be concerned? His advice was recall days before power brakes became the norm and assume that's what's happening now when truck brakes to a stop. Asked a different source and got similar answer. Been on every time I drive it and so far can't tell difference in 2000+ miles driven all kinds of traffic situations. At least the Check Engine indicator finally stopped glowing (didn't like my Universal part versus $600 more Ford part when catalytic converter was stolen for the palladium) after being on continuously 5 years account exhaust reading. Truck has 279K, original owner.

Your ABS system is in a fault condition and likely will not function if you need it.. Your brakes will work but not as intelligently as the ABS system would make them function.
