SGW 2025 Ram 1500 Big Horn

[lmftmf]

Mission was a success boys. 25 DT 35 inch tires changed tire size using a 21 WL model in Alfa and Autel scantool to unlock SGW. Afterwards I performed the proxy alignment and all is good! Did have to reset the bcm to get configuration mismatch codes to go away.

Oh, good. And that proxi was with witech? So regular guys should be able to at least make the changes with alfaobd and autoauth, then take it to a dealer for a proxi alignment afterwards?

As far as I can tell. I used my autoauth on a MK900-BTt autel scan tool and alfa obd with obd link MX adapter. Unlocked gateway using autel then with obdlink pod hooked up to splitter made the dynamic tire size change from 2480 to 2700. Truck was pissed off. Hooked up MDP using dealer witech subscription and was able to performed proxy alignment of all modules. The PCM was showing not aligned but I reset the BCM and all was good. Also ABS initialization obviously.

Sounds like we are getting closer!

So after messing around for a bit i was able to figure out how to work on these atlantis high vehicle at home. Basically to make these BCM changes you need autoauth scanner tool like Xtool or Autel to unlock gateway and then use Alfa at same time with obd splitter cable.

Unfortunately looks like cda6 is not always able to work with all modules unless you have online access to it, idk even then if it will work with online version or if cda6 is still being updated to support new modules firmwares.

With the Chinese clone micropod you can get cda6 to work on a few modules but not all. For example, i was able to get ORC, BCM and other modules to work with cda6 but it wouldn’t even connect to some modules like BSCM(Abs) module



This is the jeep WL i was working on and replaced ORC(Srs) module and successfully programmed it but couldn’t connect to Abs module for resetting it to accept Srs module. Im guessing it’s not being recognized because this firmware is not known to the offline cda6. I was even able to Proxi align with cda6 and fix the flashing odometer surprisingly.

No matter what i did cda6 never worked for Abs initialization so i tried scanner like autel maxisys 906pro($1200). It does connect to read codes etc but fails to abs initialization. Ofc talking to tech they just have no clue and keep telling to get even more expensive scanner even though they list this as a supported function.

I gave up on these 3rd party tools and went with witech. Basically what i did was use Topdon Rlink j2534 ($200ish on sale in amazon) and witech subscription was 40$ single vin for month + 45$ tech authority for 3 days. So initial investment cost is 285$ and then 85$ after that to use witech which is somewhat reasonable.


For some reason for my 19 DT i just needed 40$ subscription since SGW is bypassed and i could do everything with the exception of connecting to radio because of bypass.

But for Atlantis vehicles it requires both the 40$ and the 45$ 3 day tech authority subscription to unlock sgw which is weird and if it’s not there basically everything is locked and is in read only mode.

So BEWARE if you are working on these Atlantis vehicles you only have 3 days to make changes even though your witech vin subscription is for a month unless you get tech authority for a month as well.

Overall changes and programming is doable with 85$ subscription service for 3 days.

Hi,

Thanks for the information guys, I really appreciate it. I have a 25 RAM 1500 DT and was able to unlock the SGW just with the Autel (MaxiPRO MP900) subscription since my RAM is an international version (not US or EU) so I did not have to subscribe to AutoAuth. I've installed a visor with homelink and I tired to enable the Universal Garage Door Opener with the Autel tool but it failed. Then I've used a splitter to connect AlfaOBD but I can't get it to communicate with my truck's BCM at all. It seems that AlfaOBD communicates with the BT OBDII scanner just fine. I would appreciate any pointers on which configs (brand, Model, Function, ECU, etc.) to choose in order to get AlfaOBD to work. I've Tried all the option available for the RAM DT and none seems to be able to communicate with my 2025 truck.

You need to connect as JEEP WL not RAM DT in Alfa. RAM DT in Alfa is all POWERNET vehicles and it hasn’t been updated to support ATLANTIS vehicles yet so you need to use JEEP WL since its ATLANTIS.

Yeah, I forgot to mention that I tried as jeep WL but failed as well. I did notice that after 10 or so attempts, the autel scanner was able to test the UGDO successfully once and it gave errors afterwards. I will try until the test is successful again then connect as jeep WL in alfaobd. Hopefully it will work.






*** update ***

After several times of getting the SGW unlocked with the autel, I managed to connect with AlfaOBD. Even with the autel showing that it unlocked the SGW, I could not connect most of the time. A couple of times I actually connected and got locked out from the BCM and it disappeared from the list in the autel. I'm sure there must be a pattern but it seemed random to me. Once it finally got a stable connection I was able to change the status of homelink to present and it is working now. The autel takes a very long time to unlock the SGW so I hope during the next service the dealer won't change anything in the BCM cause it was a pain to get it to work. I've tried both the android app and the PC app of alfaOBD but the one that worked finally was the pc one.

Yes thats one thing i noticed with Autel and i tried 4-5 other scanners. Out of all of them i see random lockout of sgw as soon as i connect alfa or cda6 or second scanner. The one that worked best for me was the Xtool. It would randomly lock rarely but MOST of the time it has been unlocked and stable connection even when i swap between scanners. The one plus point is with cda6 i can see as soon as gateway locks up or unlocks and constantly monitor the status on screen.

Glad you figured it out. Im surprised that with how loaded your truck looks with passenger display etc it didn’t come with the garage opener as standard feature lol.

Yeah, it is strange that RAM doesn't include homelink in a fully optioned truck over here. I still haven't figured it out completely as the proxy alignment is still failing. Maybe the dealer can do that for me with no drama if I can't get it to work.

Yeah for proxi alignment you have hit and miss success with cda6 and witech 2 definitely works if you use the scanners and subscriptions in my above post. When you do go to dealer mention them to do only proxi alignment and not restore the whole vehicle configuration as some might do it and reset everything to factory configuration.

Thanks, I am at the dealer now and talked to the technician directly and made sure to tell him not to restore. I went with him inside and when he connected to my truck it showed up as a ram 1500 rho and a jeep wl. He started the proxy alignment process and completed it. They are on a break now so I am waiting till after the break so he can clear all the codes, test it and release it to me.

I got the truck back from the service department and everything seems to be working so far.

 

[skuppy069]

I was able to get 25 DT to take off road pages today .
Used top Don to unlock SGW
Used Alfa to configure bcm using jeep etc
Used witech to do proxi

Quick question. I’m no where near as technical as you guys, has anyone been able to change top speed? I got a 2025 limited and want to take to track but 105 won’t cut it,
