C2200 Abs module verification
I am getting brake error code C2200 using JSCAN. The ABS stability and brake light stays ON but have not had any drivability or normal braking issues that I can notice. I've been checking things like brake level, caliper sticking, etc, but everything seems to be good. I cleaned the connection with electrical contact spray. I also verified that all wheel speed sensors are working and reading the same. From what I can tell C2200 means internal fault of the module like the code says. I tried energizing the abs valves through JSCAN but it does not do anything (screen stays frozen like it can't accept). After more research I was able to verify ESP torque request "SET' with engine running, so this seems to confirm that it is getting the signal from PCM. Is there any other way to confirm it is truly a bad ABS module before I start looking for a replacement?

Well it seems C2200 is accurate for bad abs module. I installed a new module with some effort and delay and initialized it using Jscan, and everything worked fine.

One of the best things about this forum is members like you who post a problem (especially electrical anything) do your own troubleshooting, verify problem and take action. We all learn from it. I have not seen this code pop up before and am always interested when codes come up and what you have to go thru to solve the issue. That Jscan sure is a handy tool. Good work KC happy Jeepin

Excellent, curious if there is any change with the infamous tip-start cranking issue. Nice to hear that JScan came in handy!

Yes, I was thinking the same thing, it's been starting up good so far. I agree on JScan, very handy tool for sure, thank you for recommending it. I am glad I was able to confirm the fix and share with everyone.

Hi
I'm currently having this issues myself.
Just wanted to clarify that if I install a new module that jscan app can calibrate it so it does not have to be taken to dealer?
thanks for your time

Did your install clear the code for good, or was it just temporary?
Like the OP, I’m having to same issues. No braking issues that I notice, just these darned lights that won’t clear no matter what I do. Not J Scan, but BlueDriver. Looks to be the same. So if I replace the module these lights should go away?

I've had the ABS light come on, with all the associated lights, twice.
Each time, the code that came on (C2200) had one fix in the book: replace the module due to internal failure.
Before I spent the money on a new module, I thought I'd clean the harness connectors with DeOxit, and clean the ground point.
That fixed it for a few years.
The next time it came on, the previous steps didn't work. So, I did something different.
I noticed when I cleared the code, it would stay off until I drove the Jeep more than a few mph, then it would come back.
A search for my symptoms revealed what I thought would be a "too good to be true" simple fix.
Here's what worked:
Get the Jeep to an isolated road or parking lot.
Have one rear wheel on pavement, and the other rear wheel on dirt.
Clear the ABS code.
Punch the throttle so the wheel on the dirt spins to the point of traction control activation, before the Jeep hits a few mph. This will "reset" something in the ABS module before the code can reappear.
It worked for a lot of people in my search results, and it worked for me.
The ABS code and associated lights have not come back on since. That was a year or so ago.
Give this a try before spending any money.
