Oil Cooler Hose Leaking on Break Pressure Modulator

I think I may have discovered my break problem and I was wondering if you guys could tell me if this makes sense.

A while back my ABS and Traction Control Dissabled warning started coming on.

Codes were T025 and T027. Changed the hub and the circuit checked out for continuity but codes keep coming back. Now there is a mysterious T077, don't know what that means but it sounds bad.

I got this car from my parents and they aren't big on auto maintenance other than changing the oil. I decided to check for hydrolic leaks and noticed the area around the BPM was covered in sludge. I sprayed a can of engine cleaner on it and hosed it down.

ABS light and Traction Control Dissabled warning gone! For about two days.

I was trying to find the relays on the BPM (which I still haven't) and I noticed the oil cooler hoses had a little oil on them, looks like a fitting is leaking. I'm assuming this is where all the sludge came from.

The fact that it worked for a while after cleaning gives me hope that it's not a goner. Maybe the oil is just shorting out the relays or something?

Any suggestion on where to go from here? Besides obviously fixing the oil cooler hose.

Update:

It's a transmission cooler hose, oil is on the other side, not worried about that yet, though...

T077 = PCM Serial Data Link Com Fault (bought a subscription to ALLdatadiy, SWEET! ($26/year)

I took off the inside of the wheel well to give the ground wire contact surfaces a good cleaning with the rotary tool wire brush...

The ground stud is loose, it spins on the pump but doesn't come out. This can't be normal, can it?

I think I'm going to go pull a pump from the junk yard.

Anyone ever make their own oil cooler hoses?

Try Napa, take the old hose to them.

I decided I'll repair the oil cooler lines I have. The closest hose I could find was 3/8" ID transmission oil cooler hose. The original was 13/32" but I'll have to make due untill I can find the right size. Hopefully that and some fuel injector clamps will hold it.

I got an ABS module from Pull-a-part for $50, I hope it works...

No good, still have the TRACTION DISABLED and ABS warnings. :(

I think it may be in the wiring.

Now you need to get it scanned for abs codes.

Any shop with an abs scanner cartridge then they can drive the vehicle and check speed sensor inputs.
