Well I'm back I figured I'd start a new thread instead of keep adding on to the other. If searched the forums and have tried everything I found.
I'm still trying to get rid of my ABS / Brake light , light problem.
From what I found posted the front wheel speed sensors should ohm out at around 1K ohms. Does anyone know what the range is for them.
My right front wheel sensor is 1028 ohms.The left is 1032 ohms are these still in range or are they too high? does it have to be 1k or less?
I pulled the rear diff cover and drained out all the old oil.
I looked it over inside while I had the cover off and everything looked like it was in good shape. I didn't see any loose metal pieces or metal shavings in the oil that drained out.
I wiped it all down inside with a nice clean lint free cloth and then made a new gasket with some gray ATV sealent and bolted it back together. Since I have a limited slip I added the 4oz of Equa-torque and filled it up to the proper level.
I had changed out the rear speed sensor located on the top of the rear diff. in the hopes that would get rid of my ABS / brake light lights.
Like I mentioned in the other thread I had read it should ohm out at 2K ohms. When I measured mine it showed open. I replaced it with a new one and it also shows open. When I went back to the store to return it I measured all of the 3 they had on the shelf and they all showed open. I even went to another store and checked a new sensor made by a different manufacturer and it showed open. Are we sure that they are supposed to read 2K ohms.
I took the Durango to a shop to have some other work done and asked them to see if they could read the ABS System.
They were able to borrow a reader and the following codes were stored in the ABS system 65,37,35,21. I'm trying to look them up to find out what they are. I 'm wondering if when I unplugged the front right and left sensors as well as the rear and the output speed sensor on the trans. if it tripped something and just needs to be reset. Any thoughts on that from the experts?
Just incase you pros might know the codes before I can find them do you know what they are?
Thanks for your time

I had the same issue, but my assist pump ran constantly when the lights came on. This was even when the ignition was off. I was told by a shop the computer needed to be replaced. This is a pain because it has the optional 4 wheel ABS, it is very hard to find. The mechanic said that they had nitrogen in them to keep the computer cool and mine had leaked out. This would make sense since it happened when it was 95 degrees. Don't know if this helps you, hope it does.
(65,66) INTERNAL MAIN RELAY .
(37) INTERMITTENT SIGNAL FROM REAR
(35) REAR SENSOR OPEN .
(21) RIGHT FRONT SENSOR OPEN
so it looks to me like you have a couple of problems, iv never heard of the sensors being open but that first code (65) to me seems like the module might be bad, but check for an ABS relay before jumping on replacing the module (the relay is cheap, the module is not)
if i remember i will check my rwspeed sensor ohm reading tomorrow for you, but i dont believe any of them should be open.

It is in the PDC (under the hood, drivers side mid fender, in the fuse box).
I would remove the 40 amp green fuse and relay hopefully reset the module, install a different relay with the same number and install a different fuse from a different location. (had to do this to my truck the other day after plugging into a shorted trailer).
Look at the underside of the box cover for a mirror diagram.
