i have 2000 Accord EX V6, and I bought it used from another guy, and i know jus recently noticed my ABS doesn't go off. I look under the hood and i see that my ABS wire harness on my driver side is cut. I go to the dealership and say that the wire is 50+ dollars. The weird part though is that I never noticed cause the ABS light never came on. So im afraid even though i replace the wire, ABS would not work...do i need to reset the PCM/ECU or something?

go to an electrical store and buy some wire connectors and fix the wire...unless of course the connector is damaged...if you can fix it good then don't worry about buying a new one but this will at least tell you if the ABS works or not.
