ABS module compatibility?

[mrit]

So according to the 1999 Service Manual, my abs module is bad. Code C1241 - Shorted Reset Switch Circuit Failure (Hydraulic Pressure Differential Switch).

I am having a hell of a time locating a module with the same numbers as mine(First pic). I just recently noticed that the sticker on my module was actually covering a different sticker(Second pic), so I peeled it off and got a new set of numbers Anyone know if I can just put in either one? There is no info anywhere I can find about this...

Parts are no longer available from Ford, and junkyards around here don't have Superduty's.

No clue, but I am betting they are the same. See if you can find wiring pinouts.

Most of them will interchange. Is it 2wd or 4wd and is it 2 wheel or 4 wheel abs?

I should have the unit you need.

They very rarely fail though. Most of the time it's a wiring issue to the module.

Thanks for the responses. Its 4wd with 2 wheel/RABS only. Are there common spots in the harness to have issues? I have already replaced the sensor and its pigtail. The service manual seems to be pretty blunt with the C1241 code, it doesn't have any troubleshooting at all. It only says to replace the module.

Thanks

A lot of times it's the ground on the radiator support above where the pump mounts. I would try taking the ground loose and cleaning between it, the support, and the ground strap itself.

Ok thanks, I'll check it out tonight. Would be great to have a free fix. I'll post an update with the results later.

So, no luck with the ground... It didn't look too bad, but figured I would clean it anyways. Verified with my Fluke multimeter that resistance was at .5 ohm, so the ground is good. Any other ideas before I replace the ABS module?
