Once the ABS light is on there is a problem with the ABS system. You can't really guess with this stuff. Also it becomes a safety issue when abs light is on the ABS system is in-operable. Here is my advice take your vehicle to any AUTO-ZONE store and they will check for FREE and let you know why this light is on it could be anything form abs sensors(wheel sensors) or something like that, they are four of them one in each wheel so make sure to get exact info as to what is the exact code and meaning. Good Luck feel free to contact t me if ou need more info

you have an abs fault. have your abs system scanned for codes.

your base brakes will continue to function normally

SOURCE: abs codes co281 & co265

the first of the two codes is for the brake light switch, the one that is under the dash attached to the brake rod and brake peddle. Not much to diag on that one, if its bad it's bad, and when it sets the code that means it's bad.
The second one is for the abs modual, it's under the truck on the drivers side. It is bolted to the top of the thing that has all of the brake lines going to it. MOST all of the time that code is set the modual is bad. It can be a little hard to get the bolts out they are torqs 20 or 25(i'm getting old). There are four of them holding down the modual. There are also a couple of connectors going to it. And some of the time it will blow the fuse for the abs under the hood(its in the underhood fues block). Make sure to clean off the modual before you pull it out. You don't want dirt getting in the solinoids for the BPMV(that's the thing it's bolted to).

check your fuses. check your fuses. check under the hood on the top row there will be a 60amp fuse i beleive its the second one from the right it controls the abs system its blown. your probably gonna need a new altenator.
