My ABS light stays on all the time, I just dropped it off a couple hrs ago at a heavy duty truck service center to get it checked , just received a call they could not get a connection I don't know if...
I had a sensor replaced and it fixed the problem. Just in case they are looking for the computor connector, my Monaco Cayman has a connector under the dash for the MH and one over the engine, you have to remove the room panel to get at this one.
For the ABS, they have to connect to the one under the dash, driver side, might have to remove the under dash panel to see it.
