Any JScan users?

[mphilleo]

Something even better came in the mail:



This is a more easily reversible version of the Spicer FAD delete kit. Evidently, it's installed in lieu of the FAD unit on certain trims of the JL/JT (Willys, Rubicon, 392). Anyway, I managed to get a hold of one, but now I have to figure out what to do next. It sounds like JScan will allow me to deactivate/disable FAD through the program, but the programmer mentioned that some users who have done this have experienced "configuration mismatch" which throws a code (B2204). He said there wasn't enough information from the users to determine if it's a consistent issue or related to certain factors. I've tried searching the groups and Google, but haven't found anything relevant. Has anyone here used JScan to disable FAD or know of someone who can shed some light on this? Worst case, I guess I can buy a Tazer, but it sounds like all that does is suppress the error code.

FAD has been removed on all 2024-Up Jeep JL Wranglers and JT Gladiators. And, I personally think it's a bummer as I've come to really like having it. Certainly, it's far from being the weak link that the internet will have you believe it is.

That said, I have deleted my FAD on my 2018 JL or at least, back when I still owned it and because I installed a PR44. I did use a Tazer to turn off the error codes but it was never perfect. The only way to get them all off also meant I no longer had the dash lights indicating what position my transfer case was in. I'm willing to bet that will be the same problem with a Jscan but being that I've never used one to do it, I couldn't say for sure.

Interesting. My Gladiator Sport must've been an early build (the door tag shows 4-24). It's not the end of the world if I can't get a perfect fix, I just don't want to leave too many bread crumbs for the dealer if I have to bring it in for any warranty work. I'm guessing you must use the FAD for a supplemental purpose or have direct control over it?

Supplemental purpose? LOL - nah, I just like how it allows me to run a bit more caster and not have driveline vibrations especially being that my rig is re-geared to a higher ratio. I also appreciate that it offers slightly better fuel economy regardless of how little it might be. Again, since being introduced, I can't say that I've personally seen a single FAD failure. What I have seen are failures at the housing but that's an entirely different ball of wax.
