Chrysler Recalls Almost 470,000 Jeep SUVs

Superchips doesn't support CRD tuning, but that's independent from the OBD functions... your drivetrain has the same modules as the rest of ours so I don't see a reason it wouldn't work.

You're right, didn't think about it like that. I don't understand why only the Superchips have been successful in clearing the codes.

From what I've read if the update caused the problem all they need to do is reflash it until it works. Sometimes it's taken 3-4 times of reflash and then it seems to work.

This only works temporarily, it always comes back it seems. From what I understand, the only "solution" is to get a junkyard FDCM that hasn't had the recall performed on it or you can send your FDCM to blown7 on JeepForum and he can reflash it to the old software (he has StarScan).

I think we lucked out in the sense that the Superchips added a lot of "offroad" features for the JKs which required communication with the FDCM. In doing so, their programmer can read/clear drivetrain codes that normal OBDII scanners can't.

Makes sense but I can't imagine the JKs using the same FDCM because they don't have ELSDs or the NV245 transfer case. Isn't the FDCM's only function to operate those systems? Does it even matter if they aren't the same FDCMs? Sorry I'm asking so many questions, I'm just extremely intrigued by the QDII system. I've learned so much over the last few hours since finding out about my 4WD error.

Edit: Stupid question maybe, but does the JK even have an FDCM? It seems that the only reason our Jeeps have them is because it controls the NV245 and the ELSDs, which the JK has neither.

Honestly I havent looked into it that deep. When I found out I was able to pull drivetrain codes with the flashpaq I really didnt care how or why it was possible. ... the stars aligned and thats all I cared about

[jjt250]

Haha that's true. I just need to figure out a solution. Right now, there just aren't any that are very appealing.

I still have not had mine done. I just got a reminder postcard from Chrysler a couple days ago. I was holding off hoping the update would get fixed. After seeing what is posted here, I have no plans to have any update done. I don't have remote start, and as far as I am concerned at the moment, "if it ain't broke, don't fix it."

My question to those of you that have been mechanics, if I take this to Jeep for repairs of something else, or to an independent mechanic, or even a quicky oil change place, are they under any obligation/liability to do the update or can I decline it?

[jjt250]

As of now, do not get the recall done!! Only the dealer can do it I believe. You can decline the recall also, just make sure they know!
