Wrangler JK ABS Module Replacement 

So glad to hear! Thanks for the comment!

Fantastic - glad to hear!

Hope JScan works for you!

Great to hear!

Good luck! Would love to hear your results when it's done.

@@austin.gresham - It didn't take long for an update. My mechanic called the Jeep dealership just moments before we placed the order to double check that the controller module is included in the quoted part, the salesperson confirmed, we asked for the part # and searched online, it was clearly mentioned that this is just the pump and pipes, and does not include the module. We called again, sales transferred us to a technical person who confirmed the module is indeed not included and they don't have it in the country (Australia). Now back to square 0. fishing for the module online.

Hi Glenn. In my experience, when the ABS light is flashing (and no other lights) it's usually because the steering angle is out of alignment. Make sure you do a proper centering of the steering wheel using the draglink, while using JScan to check what it reports as the steering angle sensor degrees. I can't remember how many degrees "off" will trigger the ABS error, but essentially you want it as close to 0 as possible.

Well my new ABS module worked, it was almost impossible to remove from the grommets, and the bottom screws on the module were even more challenging. You need a very narrow T20 extension. Jscan abs initialization worked without having to do any other programming.

That's an interesting one. First, I would not worry that you did any damage by not opening the fluid reservoir when compressing the pads. I've done that a number of times and never damaged anything - removing the cap just makes the compression a little easier in my experience. If you think ABS is engaging, but you're not seeing any lights illuminate, then I don't think it's an ABS problem. If the ABS module was bad, you'd be seeing at least some code that tells you there's an error. I have not seen one just "stop" recognizing errors and give up. So, I guess that's the good news. Have you checked the rear pads? With the ABS, BLD rear diff, and traction control the rear brakes on these get worked a lot harder than older Jeeps. You may have an issue in the rear, including a bad E-brake shoe. I am about to post a video about these, actually, which caused pretty bad noise in a 2008 Wrangler. Other than that, you may have a driveline issue/noise, like shavings in the differential. Hope that helps!

Good Luck! For the scan tool I use a few different ones: an Innova (from harbor freight), JScan and AlfaOBD. For this particular fix, JScan was what I ended up using to get through the initialization for the new ABS module. It's an app for iPhone/Android that uses a bluetooth or wifi OBDII adapter like an ELM32 that you can find on Amazon.

FYI, got my used controller installed today and no more lights on the dash. Didn’t need to reprogram it at all. I am going to send my old unit off to be repaired so I’ll have a good one ready to go if this one goes bad. Thanks for sharing your video!

@@brianhayes7153 That's great to hear! No idea how you got away without reprogramming but congrats. Did you tell the seller what your VIN number was ahead of time? Some people (dealers) can program a VIN prior to shipping it out... just curious.

@@austin.gresham No, didn’t give the seller my VIN. It came from a junk yard in Iowa. Dodge dealer in Grapevine, TX said they had over 800 on back order nationwide at dealers. All I could find were used ones. Don’t know why it didn’t need flashing, but I don’t have any warning lights at all now. I’ll take it!

hmm... I don't know much about the icar adapter. Some functions require an OBD with more advanced protocol handling and I'mnot a CANBus expert to be able to tell you if the ABS module needs that. You could try a different adapter like the MX+ (which is what I used in this video). The other possibility is that you need to clear the VIN from the used module first using the "Clear VIN Original and Current" before the Initialization. If neither of those work, you may have another bad module, unfortunately.

Yes! I use the OBDLink MX+. You can get it on Amazon

Hi, James - skip to 11:30 in the video. Some people have not had to reprogram, but if you do the procedure is discussed at this point in the video. Good luck!

Yes, for JSCAN. If you use AlphaOBD you don't need a separate license for each VIN, but you do pay for it once.

If I have solid abs light and traction light on, do you think the initialisation was not done properly? Your input would be greatly appreciated 😊

You may have a faulty sensor, the wiring could bad, or you could have build up on the sensor from brake dust. The rear wheel hubs have the tone wheel and sensor pretty exposed as compared to the front and sometimes they get caked up with metal shavings. What is the actual code? I can also give you some electrical tests to try.

Could be the initialization, but it's more than likely being caused by the wheel speed sensor you mentioned. Another thing that can cause it is the steering wheel being out of alignment and the SAS sending bad information to the ABS controller.

Sorry to hear that. No, I have not heard of that - sounds like either a faulty module or an incompetent dealer 🤔

The "safe" answer is to call your dealership and ask. Sorry! That's a legal rabbit hole...

Thank you for your knowledge and knowledge 😊

JScan is a standalone app for iOS and Android. If you do a search for it you'll get a lot of hits on how to use it.

Process would be the same. My only hesitation would be that these things all seem to fail at some point. A used one might be close to failing depending on how many miles were already on it. If the price is worth it, give it a shot!

No, the free version only allows some basic stuff, like reading the DTC codes. You'll need the licensed version to perform the full procedure.

I'd say most vehicles with 200k miles need some special love and attention! Unfortunately for me, it's always Jeeps 🤣

I regret buying one. Worst vehicle I have ever owned. Can't afford anything else at the moment.

@@gusorviston1 What was missing? "Useless" isn't really a fair comment.
