2nd Generation Dodge 24 Valve Powertrain

I have been dealing with brake and ABS lights on all the time from key on to key off. I have also been suffering from "irregular" / "unpredictible" pedal feel. Sometimes pedal feels fine other times it goes to the floor. Braking power is still there however. So I got a hair up my butt today and started probing wires. Tested the rear ABS sensor, 1.8 k resistance, which is within spec for the sensor. While I was under there I unplugged the Sensor on the proportioning valve and BAM no more lights. So what does that sensor do? and why does the ABS computer throw a hissy fit when it is plugged in? I am assuming it is tellin…

my abs and brake light has been on since i bought the truck and after doing some reading i figured that it might be the rear sensor, so when I was at autozone ( or the twilight zone depends on who's working) I picked up a rear speed sensor. Then, i heard if the speedo is working (mine was), probably not the rear so i didn't install it figuring maybe i'll stop by my friend shop and use the snapon scanner that can read abs codes when I get a chance. Today I put the back axle up on some stands and pointed it away from the house and ran it in 6th gear, because i'am trying to isolate a 60-70mph heavy vibration and guest what no speedo. So, with the truck already in the air an…

My dealer says there is no fix for ABS CODE 84 Any thoughts

First off I got to say Thank You to @Chris O. for producing a wonderful tool for me to beta test for him. I've managed to test the speed sensors and see the right front is dropping out below 30 to 40 MPH. It drops to zero while the left shows signal. This produces weird ABS action and pulling left fairly hard. Everyone knows I've changed sensors and tested wiring. I've talked to several tire shops and found an answer. The tone ring has most likely broke free on the hub. So I'm hunting for a used unit bearing for testing purposes. Anyone have old bearing laying around?

Preempted sorry if this is in the wrong place but my truck has stumped me a little bit of history they came on about three days ago and it has no codes and it just randomly on my way home the abs and park brake light came on and the spedo bounced from actual road speed down ten to twenty mph then back up then down so on and so forth the problem isnt as noticable under thirty and its off until the truck gets on the road I have reset the computer by removing the negative cables then replaced them an hour later no luck so I removed them again and replaced the rear wheel speed sensor hooked up the cables and still no luck.the reason I put this hear is because for our trucks i…

So yesterday I drove my truck to walmart. Everything was normal. Came out of Walmart started up my truck and my airbag light came on and I’ve lost my radio, fan controls, turn signals (hazards still work), too (key on) cigarette plug. Also my truck is shifting really weird like it slipping know. My question is what all controls this stuff that I listed off? Trucks a 2000 Dodge Ram 3500 drw 24v cummins. Thanks in advance also everything I mentioned turns on when I have the key in accessory but as soon as I start the truck they go out

Hi, Excuse me to disturb you, I have a dodge ram 98.5 cummins 24v with 4wd, and I would like to remove definityvely the light on instrument panel ( not the bulb) , but I would like to remove all abs wire which go to the dash board and cause the lights on . I have changed all wheels speed sensors, and I think its now the abs module. SO As I have no money to change it I would like to remove. I imagine there is a wire behind the instrument cluster which arrive to signal a problem with abs , so I would like to cut it to finish with this. Thank you for your help.

My lights are on and it pulses like a bad rotor.Can anyone tell me what to check.I had all this problem before i replaced the wheelbearings,rotors and ball-u-joints.When i am light on them around 30mph it seems ok, hit them hard the pedal pulses.I only have a smarty to check codes so i cant get into the abs computer.

I have a 2001 3500 w/independent front suspension,is there any way to test the front ABS sensor w/a voltmeter/ohm meter?

Ok so I replaced My vss on my rear axle today now my abs/brake lights stay on! Even after resetting computer by unplugging batts for 30 mins. Any ideas? Thanks a ton.

My speedo still works so am guessing the rear sensor is still good, not a fuse prob., so I am going to take the sensors off the front of my ,wrecked 2000 3500 with auto, parts truck for me, and try them on my truck. Does anyone fore see a problem? Thanks

hello again, I noticed something funny tonight when I pulled in the driveway. after turning stereo down, I went to turn truck off, turned key backwards and pulled key out but truck stayed running then I looked over at the tach and truck was idling at 1200 for no apparent reason. much higher than usual. while it was still running I check the juice module to see if the turbo cool down was on. but it wasn't. at the time it made sense because I had just driven 13hrs. Any thoughts? thnx in advance, Bill

The ac belt on our ISX is slipping and I'm wondering if there's anything I can put on it to give it traction till we can get to a parts store.

Started up my truck a few weeks back and I heard a loud pop and hiss...I thought it was just an issue with fuel as the truck was sitting for awhile. Get back in it a week later and run AC and it's not blowing cold at all so I blew something up. Hopefully just a hose. Any way to pressurize the lines with air to leak check?

Have to change my ac condensor .some good ideas

Ok, first off I bought this truck about 1.5 months ago and before I bought it, it had two brand new batteries and a brand new alternator installed. To be honest when I test drove it I don't believe the TC ever locked up(didn't know what TC lockup was when I bought it.) The transmission fluid was real brown and smelt really burnt, so I dropped the pan and changed the fluid and filter and adjusted bands(about 6 qts is all i got changed out. I didn't do I complete flush.) So now when the truck is cold, the TC will lock up at about 45-55mph, and the transmission starts to shudder until I get up to speed. After I get on the hwy it will stay locked in for about 4-5 miles then …

Can I Test for AC ribble with my Fluke multi meter? My local Alternator/ starter repair shop can check it again but I have to remove my alt. from my truck because he only does bench testing He also said there will always be some slight AC ripple. Is that true? .

So tonight i just finished a cluster gauge install and took it for a spin. get a mile down the road in over drive 65 mph starts surging shut the overdrive off stops turn it back on starts again set the cruise still did it. go back to the shop take DMM reads .041 AcVolts. so then i started thinking that im not sure if it has ever been jumpy it with my lights off so i turn on headed lights which by the way are HID'S and it reads .72 then i turn on my PIAA fog lights two sets of them and reads .93 turn everything off goes down around .041 differently ac voltage being read.first question can testing at the batteries pic up ac voltage from other sources besides alternator?My t…

I just got a 99 dodge cummins 2500 4x4 auto trans.....spoke to mopar man last night about my lift pump not working and I havent checked codes yet but Im sure the main pump is shot too....I tried accelerating and bad hesitation and a little white smoke.....one thing im concerned about though, before it did this yesterday,the day before I was at a dead stop and hit the fuel kinda hard....it jerked 4 or 5 x's really hard....didnt feel like hesitation...felt lke the rear end was gonna come out from under it....almost like the rear tires were slipping and then catching again.....could this be related to the fuel prob?....it just didnt feel right ....it was jerking pretty hard

Hey guys, I have been having some issues with my truck under acceleration for a while now and need some help diagnosing it. My sig is current, and I have just replaced batteries, cleaned connections and coated with oil today. Before the battery swap I was having VERY noticeable surging under acceleration when cold, and it even started doing it while the motor was operating temps. I also had my interior and exterior lights flickering slightly while driving and was getting a CCD reading from the overhead off and on while driving. I drove it several times today after the batteries and I have no more flickering lights or CCD light so far. The choppy acceleration has gone away…
