![]() ![]() They promise to work with any ELM327 adapter. They promise to read all units, not just OBD2 minimum from Engine PCM. I found link to application DiagFCA which looked promising. Literally no chance to do anything more advanced than OBD2 without StarScan or WiTech Some of you probably noticed that car diagnostics is my hobby and I already shared here that was quite disappointed how is Chrysler, Jeep, Dodge protective regarding Diagnostic PID availability. And yes, it's sad.First> Safe Harbor statement, I'm in no way connected with Appcar Sp. Pre-2018 trucks, very different from 2019's. Not sure if this will work with the BCM and RFH on the 2019 truck, but that's where I'm at this point. This was possible on the pre-2018 trucks, because like I've replaced things like door modules, bcm's, and stuff, from junk yard trucks, and I've been able to update the vin's so they match. What I'm working on now, is restoring my vehicle config using a different vin all together, so like I have to find a Laramie that's very close option wise to my big horn, do a full restore using that vin, and then, see if I can get into all the modules, and update the vin. ***What's missing, is a way to do a RF Hub Config Replace all on its own,which existed on the continental rf hub software, but not the strattec. Even if you purchase a new, unwritten RF Hub, AND you have enabled the options in the BCM, when you select "RF Hub Replace" which tells the RF Hub to download the new config from the BCM, what actually happens first, is the Witech does a vehicle config restore first, so you revert back to the factory vin options in the BCM, and then the new RF Hub just gets the same config it had when you started. The problem is, on the 2019 witech system, its somewhat made "idiot" proof on the user/tech end. ![]() The door handles themselves, wiring, and the security bypass are all easy, and similar to other Chrysler vehicles. ![]() ![]() And unless it gets cracked, the only way to get this challenge-response authenticated, is via a connected witech dongle while its logged in, and online with tech authority. Yes, you may be able to get the time-expiring pin, which would be used by a locksmith for fob programming, BUT, you need the challenge-response pin in order to to a config replace on the Strattec RF Hub. SO, you cannot go into a dealer and obtain a useful PIN number, and walk out it. (this was designed after the jeep Cherokee,etc thefts that made a PIN number easy to obtain, and thus could program a new key to a vehicle, and technically steal it)Ī) first login, is a time-expiring random number seedī) second login, is a challenge-response type Pre-2019 trucks used a different system, made by Continental, which yes, used a pinĢ019+ trucks, use a RF hub made by Strattec, and it uses 2 backend logins. So here's your immediate issues if you want to jump on board with me and Jason Marsh. ![]()
