Scan the truck for trouble codes. Research any codes you find online to see what they might tell you. Even if it specifies a prticular part though you need to do proper trouble shooting first. A part might appear to have failed due to a wiring or electrical issue elsewhere. (bad ground, damaged wire, deteriorated connection somewhere in the wiring harness) There are wheel sensors to consider as well as an ABS module and a high pressure pump. The pump in particular is expensive and potentially difficult to install and sometimes when one fails it causes the other to fail as well. That was the case in an older high mileage truck I had. In the end the repair was potentially going to exceed the value of the truck so I just drove it without ABS and put up with the warning chime going off each time I started it up. Even without ABS it still had the best brakes of any vehicle I've ever owned.
Most likely a bad wheel sensor. Take it to ur local auto parts store and they will scan it free of charge
