I've had the same proboem for 13 years. Way back when, a mechanic told me to ignore it because it would be too expensive to fix the problem. Told me the ABS system would work regardless. I've put about 70k on the camper since then with no problems and several panic stops over the years. I baby the brakes anyway since the rig is so heavy and look way ahwad when driving.

I know that this is a old post but I know the 94 units and maybe +- a year or so had a main relay problem. Unfortunately the relay was part of the ABS module so the repair usually required a complete pump assembly. Some years the electrics were available separately from the pump but I don't remember what years. I usually call ford with the vin and see what's available and get the part # and search the internet.

David... since you seem to be talking somewhat specifics... I have a 1994 with the ABS light stuck on. I'd love to get it to go away, and the brakes seem perfectly fine.

Did you do this ABS module replacement and if so on what year? and or... how could I find the module's part number to replace it? or the complete pump assembly's part number? and.... is this a $100 fix or a $1000 fix?

Is it pretty easy to access and swap out?

First thing you can do is check fuse #17 20A and #1 15A in the under dash fuse pannel. Fuse V 60A and U 30A and the 4WABS Relay in the under hood fuse box near/under the master cylinder. If all is good then you need to have the ABS scanned for codes and post them. It is ODB1 so it would need to be take to a shop with the older equipment. I have been doing this for 35 years so I have everything. A shop that doesn't have the older equipment I wouldn't have them fix anything because it takes knowledge and experience to fix older vehicles. Some shops don't even know how to work on carburetors let alone early fuel injection.

Lets keep this thread going because I will explain everything in the system as we go. This will cover 92-96 4WABS.

I haven't looked into those so I will. I was told the VSSR can cause that too so I switched out the VSSR on the rear differential. I herd that might help with the bouncy speedometer too, since the ECM had been rebuilt. Thanks for the tip.
