No need to get your ABS Module replaced... they only tell you this to get more money. I fixed mine by simply unplugging the ABS Module that's located directly behind the battery. The plug connector on Dodge's has a problem letting moisture/water get into the plug. Use an air hose to blow out the moiture and you can even let it dry out for a bit. Then plug back in, and the problem should be fixed.

I tried to disconnect that plug and everything around it started to break apart. I lifted the red insert and cannot get the plug loose. But, I noticed there is an opening totally displaying the electronic board, so I am sure it got wet. What do I do now?

Yes I did get this fixed. It was the ABS Module. It's best to go to the dealer and have it fixed since you have to have the VIN flashed and computer reprogramed after the work is done .. its roughly 550.00

I had the same Problem on my 1999 2500 RAM it was the rear ABS sensor mounted on the Rear Axle

The rear ABS sensor mounted on the rear axle also acts as a speed sensor to let the abs system know the speed of the vehichle
on June 29, 2009
is it possible that both sensors could go out ?

I have a 1998 Dodge Ram 1500 Both the ABS light and the brake light are on. Changed the Speed sensor on the differential it didn't help. I did replace the RWAL/ABS fuse and now the speedo works. Next I'm checking the front wheel sensors after that idk what to try. Any advise would be helpful.

Sounds like my prob. Cheack out your abs computor eather went bad or wireing is broken. If its a van its under the battery. Dont let this go may be shorting out like mine and almost went on fire because it is still hot even with the key off!

I have a 99' Dodge RAM 2500. It started to not clear ABS and Airbag lights upon startup (go off for a second and then relight. Then if you try to operate truck, the speedometer would not work (no ODO on mine). Also, if you listen for shifting carefully, the truck was not shifting properly (probably due to no speed input - and this would explain drastically diminished MPG). At any rate after some searching, I saw that someone found a similiar problem that was due to a bad ignition switch. I played with starting and shutting off truck several times. Things tended to work better when it was hot outside. But, it also seemed like situation was decaying. But, once I accidently bumped switch (after lights did not clear) and then they cleared - this happened only once. So, I replaced ignition switch (about $63 at Auto Zone) and now everything is operating normally all the time.

I'm having the same peoblem on my 1998 dodge 1500 I replaced the abs speed sensor and output speed sensor and still no speedo or odometer or heat can anyone help me I'm low on cash and sick of buying useless parts . And my truck is starting to stall while deiving and I literally watch my fuel go down and it will start to stall so I have to pull over and then watch my fuel go back up to where It should be is this the pump or sensor ? Or is it because of my exhaust I'm running out of ideas what It could be ?

I am having the SAME EXACT PROBLEM as you Dylan (with my '02 Durango). Any solutions found?
on September 17, 2014
sounds like your ignition switch. pretty common with dodge. The switch turns back far enough to light up the dash and kill the heat but not the engine.

I don't know how to post a question, but hopefully someone can help me with a similar problem?

I have a 2006 Durango that the reverse light is stuck on, this has recently killed 2 batteries before I found out that it was the reverse light stuck on. This is not the only issue I have had with my durango and all if it seems to be electrically related. I have taken this into the dealership a dozen times with them not finding anything and $$$ later I am still out with these issues.

If someone would kindly assist, please let me know or send me an email please.

So, if you tried everything above and nothing worked, try this: Check the fuse labeled Anti Lock Brakes (#27 on my dakota slt 3.9 4x4) with a light tester. Have the ignition key turned on. See if you get NO LIGHT on both terminals. That was the problem with mine. There is no power to my entire 3rd row of fuses that includes :heated seat, anti lock brake, and reverse lights etc. To fix it, I "jumped" power from the row above at fuse #6 or 7 it was a blank "not used fuse" that only gives power when the ignition is on. (tested with light) I simply stripped both ends of a short wire and jumped it from top terminal to top terminal. Probelm my speedo, odom back, and brake n abs light off. This was all after changing sensors, tearing apart the distribution center, and tracing wires for 2 weeks. good luck!

Thanks for the advice..My 98 Dodge Magnum 2 wheel drive was put in the shop.Front and rear sensors were replaced,lights stayed off for a few day then came back on..Removing battery cables and replacing does keep the brake and ABS lights off for a day or so but they come back on.In Texas they won't inspect it if the brake and ABS lights are on,even if all the sensors and brakes have been replaced with new equipment.I even bought a used ABS module for 50 dollars and replaced it but only to find that my speedo and odom went out..I bought a faulty used Abs module...I put the old module back on and my speedo and odom started working again..If your fix doesn't work for me then right before I need inspection,I'll disconnect my battery cables,hook them back up,get it inspected immediately while those lights are out,then the next day or 2 lights will come back on but no worry.I'll have my inspection by then.

"I'll disconnect my battery cables,hook them back up,get it inspected immediately..."

Nope. Because when you unplug the battery the OBD2 doesn't report "OK", it reports "Not Ready." It will not pass inspection in the Not Ready state.

I have a 1998 Dodge Truck 1500 ..ABS light still comes on after replacing both front and rear ABS sensors and the Kelsey-Hayes ABS module ,what else could be causing the ABS light to still come on? Possible Loose wheel bearings I've been told ? Any help would be appreciated.

I have an 03 ram 3500 dually with hemi.

same prob as everyone. was getting rear abs sensor code with all the different lights coming on, no speedometer etc

under the hood on the drivers side is a fuse box-it says fuse and relay center on it. on the bottom of this there are several elec connections coming into the fuse box. in one of the bundles is an orange and black wire. if that wire is corroded/loose this will cause the problem we are all having.

Thank you for the tip,I'll try it..I did get it recently inspected but I had to start the truck and leave it running until the inspector drove it .The Abs light and brake light will not come on the first start of the day but.,the Abs light and brake light will come on the 2nd time I would start it for the day..I also noticed I could start my truck and put it in drive immediately after start up then the Abs and brake light would not come on.If I would start it up after the 2nd start of the morning and left it in park the Abs light and Brake light will always come on..Both sensors were replaced so I know its not a sensor problem.Thanks again for the tip..
