2016 Jeep Cherokee Latitude 3.2L (S EHK) 9-spd (948TE)

16 Cherokee, replaced ORC, set up under BCM with WiTech 2.0; noticed a few modules were out of date; reflashed PCM after about 10 failed attempts, now IPC won't program, tried about 30 times, using Bosch m-vci; have tried J2534 Legacy but it keeps saying license error; WiTech 2 is telling me module isn't responding to tool as expected after attempting to download data blocks; has already erased data now deeming the IPC Inop. Any suggestions are appreciated!

Had the same issue a few weeks ago. I went to a friend's shop and used his witech with the micro-pod and it flashed the cluster and brought it back to life.

I had the same problem with tcm in a 2016 cherokee. erased the tcm and would not program. I used an aez flasher and the guys at ae tools bailed me out by lending me a micropod.

Do what your getting paid to do and quit. If your going to go onto other modules and update make sure you do a proxi alignment first and make sure all is well. No issues with the Plus 3, left my micropod in a customers car once and hardly used it again since after it came home.

I agree, have programed several modules as new 2020 with Plus 3, no issues.

Micropods aren’t that expensive. The real only tool to use. I have never killed a Mopar module and we’ve done thousands. Also don’t do updates unless they have a specific complaint that has an update. Some updates require parts. Don’t replace the part and now you have a light. Some will change the way it operates. Customer no longer likes the way it shifts? Sorry, no going back. And, some…

I would say that this goes for all manufacturers. Either get an oem or validated device and do flashes only when needed.

Unfortunately, you got caught in the ‘update’ trap. Never update anything unless there is a dedicated reason for doing so. As an instructor told me years back: a flash will not usually repair an old vehicle with an issue. Most flashes are for issues that occur under warranty. But, some are not…no way to tell, unless the flash deals directly with the issue at hand. That said, a micropod usually…

Something isn't adding up…..it is either an equipment issue or internet latency. Obviously we cant rule out the vehicle itsel having intermittent COMM issues. Never have I had to make 10 to 30 attempts on a Chrysler module….PCMs and TCMs are straight forward and are everyday updates across the nation. It is a day later and you may have moved on. Next time you get jammed up, if you have access…

I'm leaning towards an equipment issue, this old Bosch M-VCI has been an AMAZING tool but I think she's reaching the end of her serviceable life. My 3 day subscription is up, I'll resubscribe when the micropod arrives.
