Didn't check the diagram on the web, but compared wire harnes between 2 of my trucks, and my old truck missing wires for front sensors, but my "new" truck has them (both 2000 f250. Old is 2wd XL and new is 4x4 xlt). However, as I understand, some 2wabs trucks came with those wires conected to fenders, but had no front sensors.

OK, the module is physically broken, but I'm not sure what the problem actually is. Are you trying to figure out whether you have 2 or 4 wheel ABS so you can get one? Is there a wire that goes down to each front hub unit attached with plastic clips to each front brake hose to the caliper?

If I took both abs module and pcm from 2wabs, then those should communicate together and ignore absence of front sensors.
Pix of both abs module part numbers, look to be the same.

I have no way of contacting previous owner(s) to find out and dealer is no help.
Truck is throwing code C1185 that I can't figure out.

It's really unlikely that someone pulled the sensors out and went to the trouble of changing the module to match the new configuration. The truck was probably RWABS originally. C1185 is ABS Power Relay Output Circuit Failure.
PINPOINT TEST G: DTC 1115/1185 — POWER RELAY OUTPUT CIRCUIT FAILURE
CONDITIONS
G1 CHECK CONNECTOR C1041 (2 WIRE)
Anti-Lock Brake Control Module C1041
G2 CHECK GROUND CIRCUIT FOR AN OPEN
G3 CHECK BATTERY CIRCUIT FOR OPEN
DET AILS/RESUL TS/ACTIONS
Inspect the connector wiring and terminals for opens, corrosion looseness and backed-out pins.
• Are the wiring and connector OK? Yes
GO to G2.
No
REPAIR as required. TEST the system for normal operation.
Measure the resistance between control module C1041, circuit 530 (LG/Y) and ground.
• Is the resistance less than 5 ohms? Yes
GO to G3.
No
REPAIR the circuit. TEST the system for normal operation.
Measure the voltage between control module C1041, circuit 532 (O/Y) and ground.
• Is the voltage greater than 10 volts? Yes
REPLACE the control module.
No
REPAIR the circuit. TEST the system for normal operation.

Let me try to clear things up a bit, if I can. Some f250 came from Ford as 2wabs and some as 4wabs. So, if my truck came as 4wabs and I disconnect front sensors, it will thow a code (s). If my truck came as 2wabs, then it is not even reading front sensors. So, the question is - what is programmed to reed front sensors - ABS module, PCM or what? In other words, if my truck is 4wabs and I try to convert it to 2wabs, what parts do I need to change to disconnect front sensors and not get any codes?

It should be just the ABS module, but I'm really not sure if there are any differences in the wiring harness or not. I'm not sure if any unnecessary wires were omitted or if all harness had all the wires and connector pins. It would make sense to use the same body harness, but you never know what accountants can force engineers to do to save 4 cents per vehicle . . .

My head about to explode as it is, so I will take a minute to figure out the test u recommended.
Above pictures of both abs modules and I don't know which one of those numbers is a part number, but most of them look to be the same.

Got this from pulling up 4WABS ECU - see service message 13384 for instructions, 4 wheel ABS, BEFORE 12/03/00
Ford 250 Series
EDIT: There is a difference between the two. Your numbers match the discontinued 2WABS Module.. But only can find a 4WABS for sale new or reman. Maybe they combined the two?
Come up: Bulletin Number: 13384 Bulletin Date: 10-01-1999
Component:
Service brakes, hydraulic:antilock
Summary
Exhibiting abs codes of b2141 or b2477 following replacement of a gem module. *tt
It looks like you were right, they are interchangable from digging through about 15 parts list and a TSBs.
C1185 - ABS System power relay output circuit malfunction
Are you getting 12v to the connector?
All the research I can find points to the ABS Module, but a swap for a good module is suspect it's wrong.
Check power, fuses and wires?
EDIT: I was hoping the manual guys would come out.

They may actually be the same physical part with different programming. The service manual does say when a module is replaced, to suck the programming off the module being replaced and paste it into the new one.

Well, if you consider that ford charges about $250 per sensor, everything is possible.
My head about to explode as it is, so I will take a minute to figure out the test u recommended.

Just found that as well. Sorry I am slow and off tonight. I bow out now.

. Going back out to check everything again. There were few torn wires, but I think I found them all and fixed them. Fuses are ok. Which wires should I check for 12v?
