Hi Guys new to the forum.
I tried to read everything that has been asked allready before I posted but so far no help with my problems.
I have several issues but I'll try and keep this post ABS related.
I have a 1999 Durango SLT 4X4 with the 5.9 V8 4 wheel ABS (or 3) from what I can tell. I have wheel speed sensors on front wheels and a sensor in the rear diff.
Problem:
ABS light on, Brake light on, no problem with speedo.
I tried checking the front sensors with a DVM first.
Pass showed 1k ohms
Drivers showed open. I pulled drivers side and noticed it was very dirty. After cleaning it I decided to just check it with the DVM and it showed 1k ohms( actually around 998 or so) so I stuck it back in. I then decided to check the rear sensor in the top of the diff. It showed open. I bought a new one ,brought it home and checked it with the DVM before I installed it and it showed open. WTH, is it bad? I but it in any way.
I tried the reset. Negative terminal off, key on, brakes held to the floor for 15 or so seconds. Hooked up battery started car lights still on, so I took it for a little spin on the freeway and some surface streets. Lights still on.
Do I need to reset it by way of the diagnostic reader or something?
I have issues with the cruse control as well but will try and post in a different thread unless you think it's related.
Any help or suggestions appreciated.
Thanks for your time
George

Thanks guys for all the ideas.
I'll check them out and report back.
She just left with the thing for most of the day so I won't be able to check them
until she returns . Are these switches Normally open or Normally closed when checked with a DVM ?
I'm guessing they would be N.O..
What do you think about the new rear speed sensor I bought.
It showed open right out of the box , not 2k ohms like others have suggested.
It was made by a company called Standard Motor Products.
Part# was ALS203 there is also this # on the box M11004
Once again thanks for taking the time to try and help me out.

A faulty switch on the brake pedal might affect cruise control, but it won't cause the brake and abs warning lamps on the dash to come on. I would tackle this one after solving the ABS problem.
ABS sensors on the front hubs and rear diff should not read open. The new one was probably bad out of the box. Off-brand parts are not always a bargain when it takes multiple trips to the store to get a good one.
A dirty sensor will not affect the internal resistance, although it might cause a sensitivity problem if the crud is metallic.
If a sensor reads open and 1K ohm at different times, chances are it's failing. Make sure the probes on the tester make good contact with the leads to the sensor.

For the record, Standard Motor Parts is not off brand by any means. It's what most of my engine parts when I did a re-do of all sensors and everything are made by Standard Motor Parts which is the main brand Summit Racing Equipment stocks.

Hi!
My problem!
Lamp ABS and Brake, but shines not at once, at times 15 minutes aren't present light, and sometimes in 1 minutes lamp light on.
ABS can work some times while there is no signal, speed shows correctly.
Esteemed a theme and hasn't understood where to search for the answer?
To buy the new sensor (who now part?) or to look contact at pedals?
If to look that where exactly?
The parking brake badly works for me, after pressing hasn't returned back.
I pull its hand.
It can cause?

Rear speed sensor
Hi Guys
I'm back at it.
I just had a thought. Should the rear diff. speed sensor still read 2k ohms no matter if it's mounted in place or right out of the box at the parts counter.
The reason I'm asking is I pulled the thing out again and took it to the parts house. They had two in stock (standard part #ALS203) both read open. I went to another parts house and they had a different. manufacturer but it read open as well. So I was wondering if it had to be mounted in place in order to take my ohm reading.
I checked the sensor on the trans output shaft while I was under there and it was around 680 ohms.
Still scratching my head.
Thanks for your input.

ABS/ BRAKE light issue in a 99 Durango 4X4 with 5.9
More questions. Regarding the ABS and Brake lights
I replaced the brake pedal switch while I was at it and topped off the brake fluid (It wasn't much below the full mark).
This morning on start up all the lights went out even the ABS and Brake light.
They stayed off backing down the driveway and driving down the street. Then a few minutes later they came on.
Ideas???
Also still no cruise control .
The light comes on for a second then shuts off by itself. then it won't come back on unless I shut off the car and restart it and then it only blinks on for a second.
Ideas??
Still wondering about the sensor in the rear diff.
I can't believe that I went to two stores and checked 3 new sensors from 2 seperate manufacturers and they all read open. I was using a FLUKE
DVM ( I know bring on the Must just be a Fluke jokes)
And before anyone asks yes I know how to use it it was set on the ohms setting and i made sure it was working.
Thoughts??? Ideas????
Thanks

did you try the output speed sensor on the transmission? its on the driverside of the transmission tailshaft and is also known to cause the same problems as the rear wheel sensor. This sensor is cheaper, and when i had the problem with it on my old truck the lights wouldnt come on till it shifted out of 1st gear.

Not sure if it reads open all the time unless metal is under it and closes the switch. I couldn't find a ohm reading for good or bad switches, but what you describe it sounds like the rear switch. You might have to brake down and take it to a shop to have the ABS system read?

Thanks guys.
I did check the output sensors with a DVM and it read what the others have said it should so I left it alone.
I did put the rear sensor back in place and bolted it in and checked it with a DVM still shows open .
I might go buy another sensor .
I did notice allot of stuff stuck to it when I pulled it out. (metal shavings)
