This video explains how I diagnosed that I needed to replace the Anti-Lock Brake System (ABS) control module in my 2011 Jeep Wrangler JKU. It shows how I not only had the ABS and Traction Control instrument panel lights but also the red BRAKE light. Getting just the ABS and Traction Control lights is common when you have a wheel speed sensor fault. The BRAKE light isn’t common and, ultimately, pointed me to the ABS control module.
The video then shows some overviews of how you replace the control module. It’s a pretty easy task to do yourself and save some money over the dealership. The part is cheaper than from the dealer and you don’t need to pay dealer labor. You’ll still need to go to the dealer so they can flash/update the new control module to match your Jeep since they are VIN-matched. Total cost at the dealer for the flash was $165 in a May 2020.
When you get your part, contact the parts supplier and make sure you get the proper part for your VIN.
The part that I needed was part number 68089120AB, “Anti-Lock Brake System Module.”
Part 68089121AB, “Anti-Lock Brake System Module,’ will ALSO work in my 2011 JKU but would not work for my VIN. Unhappily, the part I needed was about twice the cost of the other part.
I got my part from dodgeparts.com:

I found your video as I’ve narrowed it down to the module…initially thinking it was the clock spring until today when the BRAKE light came on, then off. Great job on the video!
Thanks, Michael!
Thanks for the video and getting to the point. This is what I love about the Jeep community. Plus, a lot of us are DIY type folks. Saved me some time.
Glad it helped. Thanks for watching.
Thank you so much. I just replaced my ABS module using your video. In and out in 20 minutes. On my way to get it flashed by a friend who owns a Jeep shop.
Excellent news, Kirk! Thanks for watching and I'm glad it helped you out.
Where did you get it? Jeep says no modules available until maybe mid 2022. I found one in the junkyard but the dealership says I can't use it. Now I'm screwed.
@@emmettbrandon2594 I got the part from dodgeparts.com - there's a link in the video description.
I know this reply's a month late but I hope the repair goes/went well. Thanks for watching!
Great video man! Thank you for all of the info.... looks like this is the route I'm headed.
Thanks and good luck with your project!
Just paid shop $73 for diagnostics at a shop. They said since dealer needs to flash anyway, they can't do it. Thinking of changing ABS module myself, I have a high DIY skill. thanks for the video.
Sounds like you should be able to take care of it yourself and save the high cost labor time of the dealership doing it. Good luck!
Thanks for watching.
Seems our jeeps are alike. Not only did I watch your video on the power steering replacement, but I am also dealing with ABS issues too. It is showing c102b, which is the abs circuit. I have already replaced the right rear sensor and cleaned the area the sensor faces. Still getting the U1418 code too.
Oh man, it seems like ABS related issues are some of the worst! If you end up buying a new control module, make sure you confirm that you get the right part number for your VIN. One thing that I don't think I covered well in the video is that you can't get the dealer to flash the module in advance - they do it through the ODB2 port so it's got to be installed in the vehicle first.
Good luck!
Thank you for the video it was informative. I could not figure out what was wrong with my jeep but I suspected my ABS module after watching this video and reading the comments. If anyone is driving and it feels like all of a sudden you’re pulling a 5000 pound trailer and then it goes away when you let off and it does it multiple times then the “brake” light comes on and it drives fine its this issue going out. I have a 2008 JKU that I only drive around town and I’m running 40 inch tires. It is mainly an off-road rig so instead of shelling out the $500+ I pulled the fuse J7 for the ABS Valve. It is driving fine and not acting erratically with no CEL but the brake light does come on. If you pull J6 you get a CEL and lose your speedometer. It seems fine so far so Im gonna leave it like this. My ABS and ESP/BAS light has been on for like 8 years from a broken wheel speed sensor. I could care less I just want it to drive and not drive for me. Its gonna all be deleted soon when I drop in a 4bt now that I got out of Commie Colorado. Hope this helps!
Wow, that’s a cool tip. Thanks for sharing and thanks for watching.
Car with squiggly lines light= traction control light 😉😊😊😊
A traction control system, also known as ASR, is typically a secondary function of the electronic stability control on production motor vehicles, designed to prevent loss of traction of the driven road wheels.
Very helpful I have a 2016 JK experiencing the same issue. My codes flash randomly while driving though and have got a partial shutdown before so it is getting a little scary. Will try this for sure.
Thanks for watching, Timothy, and best of luck resolving the issue on your JK!
I have the same issue with my ABS,brake, and Traction light came on,I tried changing out the brake switch same issue.
Thanks, great no nonsense video. Got the same lights (+ESP BAS) and C2200 code and looking for a good resource to fix, looks like I'll be doing this and getting it rebuilt. Found a company that does this, no reflash needed since it's already VIN matched.
Thanks for watching and the feedback! Good luck with your fix and cool that you found a place that will rebuild it for you.
Can you pass me the place's contact information that rebuilds them please?
Where can I have mine rebuilt?
@@TheRealisticTake the one i found is called Upfix
How long is the turnaround from Upfix , and considering the abs system is already disabled when this light is on, are you still able to drive your wrangler while waiting for the repaired part to arrive ?
I was having the same problem. Had the ABS/PCM replaced and the problem came back. I found out that my battery terminal cable was loose and when I tighten it the problem went away. Every time there’s a vibration in the jeep, the lights come on on my dash and than goes out. Took awhile to figure out, but it worked
Great input, Oscar - folks should check their ground connection to the battery. That connection being loose can cause all sorts of different gremlins, it seems. Thanks for watching.
I have the JK Hemi 6.4L and my TIPM blew. I replaced it with a used one and all is well EXCEPT, your exact problem. Turns out with the Hemi swap, everything registers ok with a new TIPM except the ABS module due to that swap. I have to take it to the dealer to get my VIN reprogrammed to the TIPM. I had the exact same idiot lights as you.
Hey Ed! I'm one of the seniors at H's CAP squadron. I have to do something similar to my Tahoe. Unfortunately mine is mounted under the truck, on top of the frame. I read on mine that the vast majority of the failures is due to some of the major solder terminals losing contact, so I'm going to try to re-flow those joints and see if that fixes it before shelling out the couple-hundred for a new one.
Wow, what a small world, Brandon! Under the truck on the frame certainly adds a lot more work to it than the easy access with the Wrangler. If you're able to recover it with reflowing the solder, that's awesome! Avoiding the double gut punch of part cost + dealer cost is certainly worth the effort. Good luck and thanks for watching!
Thanks brother that did helop
Excellent. Thanks for watching!
Screws were a MAJOR pain. Access through the wheel well (removed fender liner). Also helps push from below on the socket/pins while using a prybar to lift as well. Drilled holes in the plastic case (over wheel) to get strait access to the lower bolts on ABS computer. ONE WAS FROZEN after all other options, used a grinder from underneath to cut the bolt. THEN, everything else went smooth. Replacing the ABS computer and bolts. $150 for ABS unit from AAA Auto Salvage (used only the computer). Still need to get ABS flashed I would suppose...
Oh wow. Thanks for watching and the insight, Jeff. Frozen bolts - the Jeep nemesis!
Were you able to get your junkyard ABS flashed? Did it work?
@@emmettbrandon2594 I was told it would NOT.... since it cost $225 (for a guy who would come to me and do it) . Since he live nearby, I said pay $100 for a fail and $225 if it worked... he decided to try for the $100, but to his surprise... it worked just fine. (just doing it to get the warning lights off, everything worked fine) I gladly paid $225. Total only $375 for new computer side only. He said throw away the rest of the unit. Not bad.
Really wasn't to much trouble. Hour job on a bad day (including removal of the fender liners and replacement). If you have a better way to get at the bottom bolts while you manhandle the unit, even quicker. Always worried I was being too rough on the unit and would cause a leak. Praise the Lord, all is well. The video opened my eyes to a LARGE savings!
@@ps11514 thanks for the feedback!
Do you know if you can use different model year abs' on other model years? I have a 2016 and was wanting to go to a junkyard to find one.
Thank you for the video I change the brake module of my jeep I bought a used one and some of the lights went off I still have ESP BAS light on you think is because I need to take it to the dealer to get a flash
Yes, those should clear after the dealer flashes the module to match your VIN.
If they don’t clear, you potentially also have a bad wheel speed sensor so that’s probably what I’d investigate next. But hopefully they clear after the flash.
Thanks for watching.
Before anybody goes replacing an expensive module like this, they need to check to make sure the GROUNDS are all good and clean from the grounding bolt on the driver's
side fender to the PCU and the ABS module. These ground wires are crimped and NOT soldered and they corrode pretty fast. Check, clean and maybe solder them FIRST...!!!
Don't forget to unhook the battery before you start working on these ground wires...!!!
My code registering as P0573 and have that same flashing Traction light,brake light,check engine lights will kick in, and ABS light will flash on the dash. I had changed out the brake switch inside my 2018 JKU still had the same problem.
I don't really have much insight on this combination. Since you've got a P0573, you've obviously got the check engine light, that you had read and got the P0573. I'm assuming you also have the ABS light? If yes, have you gotten that code read (might need to find an auto shop vs. AutoZone, etc. that have a reader to read it) and see if that helps you track it down? Sorry, not much help - I haven't seen a combo ABS + check engine light on my vehicles (yet).
Good luck and thanks for watching, though.
I have the same issue with our 2015 JKU Sport. I was told the part is on national back order.
Ugh! 👎
Thanks for watching. I hope you're able to get the part soon!
What is the best way to get the right part, in my head I’m not entirely confident an auto parts store deals in vin correct parts? Possibly but not sure
Thanks for watching (and sub’ing?), Garret. I was really nervous about this too. First, I decided to go with a Mopar part. Mopar direct is really expensive but a lot of Mopar pats sellers exist, like the one I linked in the video description. Then I contacted their customer support to confirm the part number I needed for my VIN. (I actually had it wrong at first; mine was the more expensive variant of course).
There’s another comment on this video that found a service that will accept your original part and remanufacture it if you want to look into that and can be without your Jeep during that timeframe. I hope that helps and good luck!
So do you install it first and then have the dealer flash it? What does flashing mean in this case? I’m having the same problem so I want to replace it myself.
Flashing it means that the dealer connects some sort of programmer tool into your OBDII port and reprograms the new ABS controller with your VIN. That way the Jeep’s computer will talk to/interface with the new controller.
Replace the part first, then take it to the dealer (I had to make an appointment).
That’s for watching and good luck with the repair.
How much the dealer charge you to program the new module?
Thanks for watching!
Total cost at the dealer was $165 in May 2020.
Is it necessary to have the ABS Module FLASHED? to match the VIN or I could forego such procedure. Please let me know since there is no authorized Jeep dealer where I am
Thanks for watching, Felix! I'm not a Jeep technician or service advisor so can't say for certainty but my understanding is that your ABS won't work unless it is flashed so that it matches your VIN; otherwise the vehicle computer won't recognize it. Can this flashing be done with a tool other than at the dealer? I don't know; sorry.
I currently have the same lights on my dash. I also have the esp bas light on top. I changed my rear sensors last night and nothing changed. I’m wondering if mine is also the module as well. The only difference is that esp bas light. Any thoughts?
I think that's what I had when I had a bad wheel sensor - ESP, ABS, and the stability control light. The new one for me that alerted me to it being different was the BRAKE light. Then a lot of googling and trying to replace wheel sensors. When that didn't help, I bit the bullet on the ABS module - I was reluctant because it's much more expensive.
I wish I could give you a better answer, but I'm not 100% sure if yours is or isn't the ABS module. You could try taking it to a shop that can read ABS codes - that should really tell you the answer.
Good luck and thanks for watching the video (and subscribing?)!
I also have all 4 lights on. My husband changed the rear sensors and they are still on. He changed the front sensors last year. But my oil light will flash on and back off some as well.
Grommets will be vibration dampening blocks won’t they?
Yeah, you’re right. They’d do a good job isolating the module from vibrations.
So if I have my own flash cal do I still need to go to the dealer
Thanks for watching! To be honest, I don't know. It was explained to me that the ABS Module needs to be flashed/programmed with the VIN of your vehicle so that the modules can communicate properly with the computer. If your flash cal says it can reprogram the ABS module, then it might work. I'd suggest reaching out to the manufacturer of the flash cal device you own.
Tengo el problema con los testigos abs brake esp y control traccion, consegui un módulo abs y ya se comunicó con la computadora pero no deja hacer su reprogramacion, alguna idea de que podría ser
Pudiste arreglar tu problema yo tengo el mismo
@@joserosas2715 el cableado amigo, que te lo cheque un especialista
How much did the dealer charge you for the reflash?
Total cost at the dealer was $165 in May 2020.
Do u have a link to where I can get the computer that u use in the video
Links for the parts I used are in the video description. Thanks for watching, Matt.
I’m having this problem but also my mileage light is also flashing is that true
I’ve never heard of the odometer blinking before. I’m not sure if the issues are related. I hope you’re able to figure it out! Thanks for watching.
My 2012 Honda Accord has the same lights on too, should take it to Honda or a regular mechanic?
I don't have any experience with Hondas or Accords, so I'm not able to give you much advice. That said, I'd probably start out on Google and CZcams to see to try to learn more about it. Maybe there's some info in an Accord forum online? Or someone's made a video or two on something like this? That way you're more informed on the potential issues before you take it to a mechanic or dealer. Japanese cars seem to be more particular about some of the parts used on them, often (but not always) seeming to need parts from a dealer. I'm afraid I'm not much help other than to say to look and see if there are others online that might be able to help point you in the right direction. Good luck and thanks for watching the video!

It’s okay thanks for trying to help
I had mine replaced about three years ago and here I am again 🙄
Oof! That’s crummy. Sorry to hear it. 😞
I have the same idiot light composition on my jeep. 2012 wrangler sport. I have been told that the ABS control module also sends signals to the transmission. Has anybody had problems with the vehicle not shifting properly. My Jeep does not upshift past second gear, which obviously causes the RPMs to go sky high. Just wondering if these two problems are related. Thank you all.
FWIW, my symptoms didn’t have any shifting issues. The Jeep was normal aside from the lights. That’s just one data point, though. I hope you can figure it out (and find a part! It’s crazy now how hard they are to find now).
Thanks for watching.
How much did it cost to have the dealer flash it for the VIN?
Total cost at the dealer was $165 in a May 2020.
Can a bad ABS Control Module cause your jeep to turn off?
I’m not an expert in this area but I wouldn’t think so. It should just preclude your ABS from working and give you a warning light or two. I’m not positive, though.
I can purchase a used ABS module online but the dealer said this part is VIN burned so it can't be changed. My options were send off to be rebuilt or pre order new and wait up to a yr due to national b/o. Is this true or can u just buy one from another Jeep, install it and have it reflashed? There is so much back and forth on this. 2015 Jeep Wrangler Sport Unlimited 3.6L
Unfortunately, I only know what my experience was, and that was with a 2011 Wrangler with the 3.8L engine. For that part, I don't know if it already had a VIN flashed to it or not when I installed it, but when I contacted the dealer (after I'd installed the new part) and told them what I'd done and that I wanted them to reflash the ABS module to my VIN, they just told me "sure, let's make an appointment."
Maybe the only thing I can suggest is contacting a couple of different dealers (or go to one and talk to one in person) to see if they really can't do it on parts for the 2015, or if the dealer you contacted just didn't want to.
It really only took about an hour for them to do the job and it seemed like it was as simple as hooking their computer up to the OBD port and doing "computer magic."
Sorry I can't help more - once you figure it out, it would be great if you could leave another comment as I'm sure others have the same questions.
Thanks for watching.
@@CarbonsDIYGarage thanks for the response. To clarify did you install a brand new part or a used part or a remanufactured part?
@@not-AI It was brand new from dodgeparts.com (full link in video description).
did you lose power at all when driving?
No power problems at all. Drove just like normal. My understanding is that in this condition, it's just that you won't get ABS activation if you slam on the brakes.
Yea I'm having driving problems. I can be going down the road and my vehicle stops the let's up really quickly. Then the traction control, brake and abs come on. I'm thinking of pulling the fuse until I can get it fixed
This part has a 3 month back order now. Same issues. 2018 JL.
Oh wow, that's crazy! This shouldn't be a part that fails so often that there's such a huge back order. What a pain!
Thanks for watching, JG.
It is now May 2024 before the part is available for a 2012 jeep wrangler sport.
Man, i ended up changing out the star Canbus and it fixed everything. Well, so far. Buying a jeep is like buying a boat. Best days are when bought and sold@@MS-pk7hx
@@MS-pk7hxyes I can not find one
@@MS-pk7hx im still waiting now over 6 months for mine, have you got one yet?
You can just leave the negative battery off over night and that will be the same as the dealer flashing the computer and clearing the code.
Leaving the negative battery terminal off for a while will clear the code but I think you still need to update the memory/EEPROM in the module to have the same VIN as your vehicle. Folks can certainly try the battery disconnect first but I'm thinking the ABS malfunction light will come back because the VIN in the module won't match the VIN of the vehicle. But it's a cheap and non-damaging thing to try. Folks should leave a comment if it works!
I will try that overnight.
I just had this come up on my 2016 Jeep Wrangler. Is it safe to drive till I can get the part and fix it?
Since it’s an important safety system, keep in mind all the disclaimers in the description of the video…
That said, an ABS light/fault should just mean that systems that use the ABS won’t be functional until the issue is resolved. This would be the ABS but possibly also things like stability control and cruise control. The vehicle would still be drivable. I drove mine (2011 JKU) for several weeks before fixing it, just recognizing that I didn’t have functional ABS.
I hope that helps and good luck; thanks for watching.
@@CarbonsDIYGarage Thank you very much! May have no choice but to wait, apparently the part is back ordered.
@@lisachiatto821 It's pretty crummy that you're having this issue with a 2016 (and apparently so are many others)
@@CarbonsDIYGarage yes and this is actually the second time there has been a ABS issue. The first time was probably 2017 and it turned out to be a wheel sensor. It would apply the ABS while I was driving! Almost caused an accident.
@@lisachiatto821 That's super frustrating. Yeah, wheel speed sensors have been my first go-to when I have ABS lights on the Jeep. I don't know if I mentioned it in the video but I did try replacing a couple of sensors before I landed on pulling the trigger to replace the control module.
Those lights are so annoying. I have had the abs and traction lights for over 3 years. No codes thrown. Changed my clock spring, brake switch and all 4 wheel sensors and it still comes on and off lol
I have to assume that every JK owner has the same inner "groan" and "ugh" when these lights appear. You never really know what will eventually get them to go away...
Thanks for watching, Will!
Pull the fuse lol
@@SiscoSelzun exactly what im thinking. I dont need abs with the turtle way I drive.
What was the code number? Do you still remember?
Unfortunately I don’t remember the code. I think it was the BRAKE light in addition to the standard lights you get for a wheel speed sensor is what set me on the path of ABS Control Module.
The code number for mine was C2200
Yeah mind didn’t work til they reprogrammed it
Its esp or electronic spin protection, not squiggly car light!
Ah, that makes sense. Thought squiggly car light sounds more fun... :)
And thanks for watching!
Worse car ever this is the 23rd part that I need to replace in this crap🤦🏻♂️ why toyota don’t make jeeps
