Had the dreaded brake, abs and tc lights come on in my 95 classic LWB. Was able to research the codes and tapped the front left sensor . Codes where then cleared. Thought all was well as I took the beast for a ride. When I got back home and switched off the ignition and the abs pump kept running. I had to disconnect the battery to switch it off. After more research I replaced the abs relay under the drivers seat, but this did not. Switch the pump off! Now what? Bad ABS pump?

If the accumulator is failing it will not hold the pressure to shut the pump off.
Also the pressure switch on the pump could have failed as well.

Falconworks has a book that explains it.
