How To Use AlfaOBD On 2025+

[jpbr2025]

Since the xtool is the only one that can reliably keep the sgw open while making changes through alfaobd I figured id order the xtool xts500. Should be coming in mid week so next weekend I’ll test and see if it can successfully perform the proxi alignment of all modules and I’ll keep you guys updated

 

[JDHarris]

The Cardaq 3 has been stable and responsive, but I do have the 4 modules that don’t respond to proxi alignment. I can connect to the 4 modules directly, but they don’t proxi align. It doesn’t seem like a device issue to me, but it may be.

Has anybody successfully changed tire circumference in AlfaOBD and successfully aligned proxi config afterwards, with any device?

I'm just here for moral support and hoping you guys, who are much smarter than me when it comes to this stuff, figure it out for us common folk. I need to enable power folding mirrors on my dads 2026. Seems like progress is being made though!

I'm definitely cheering you guys on!

I'm also full of questions.....

For example, can we use AlfaOBD to change things like the "Unintended Idle" 3 horn blasts when exiting the running truck or, perhaps, the "Comfort Temperature" setting from 40 degrees F to 50 degrees F? FYI.... I live in the South; 50 F is cold for me...

Download Alfaobd and go through all the available settings in the body computer under Cherokee WL. It can only change options in the BCM body control module not the rest of modules.
Watch a YouTube video to learn how the app works, lots of resources, it's the same app that's been around for years.

The app lets you see all options on your phone and not connected to truck. You're asking basic questions here that you can easily answer your curiousity with doing a bit of research. Jimmy has used the unintended idle alert as his example in how to use it as it was first change he tried. So yes that option is available. I've also posted a list of proposed changes which is really the predominant ones we have access to in the BCM a couple pages back in this thread. Review that and see that options there are.

Download Alfaobd and pay for it if you need to.
Go to jeep Cherokee WL and then body computer
Then active diagnostics ( car with hood open bottom right)
Then select car configuration change
Then scroll through available options

They may not all work. This isn't perfect or as ideal as you may hope it is.

Credits really go to the pioneers in this. Some of us recently are just following in their foot steps trying to get it to work.

Edit deleted YouTube video showing cardaq 3 vs MDP pod speed in Witech 2 flashing demonstrating MDP was much faster. Deleted to not dilute thread

5y old YouTube video shows speed difference of cardaq 3 plus j2534 vs official micropod on programming TCM and PCM with Witech 2.0

34 mins with cardaq 3 plus to do TCM
4 mins with micropod to do PCM flash.
he believes both should have been comparable size. interesting. also it seems Autel tools haven't played nice with Witech for people before.

there is an interesting xtool vci that might work.

This isn't perfect or as ideal as you may hope it is. Unless you're willing to spend the money and time learning how to do it there is no point. It won't ever be easy due to the new security gateway.

Unless I’m missing something, cardaq 3 comes up as $1900. You can buy a brand new official MDP for $1850, so not sure why the cardaq would even be considered?

Unintended idle alert yes, but alfaobd can’t change the auto on comfort seats and wheel temps that they come on at. That change is made in the seat module, and alfaobd can’t connect to that

I agree I thought I didn't post that and will delete that video reference, had it as draft from yesterday. I was just showing how fast the MDP pods are with Witech compared to other good j2534 tools even cardaq being much slower for flashing. However decided not to post not needed as it just dilutes the main goal of figuring out how to get proxi to work now using cheaper tools.

Totally agree on what you say above. I'm taking that approach. I stated my question poorly, though.

What I really meant to ask was if the proxi alignment is required if only changing settings such as the unintended idle setting or if that can be done without triggering the need for the alignment.

At the end of the day, I'm new to this effort and, as most videos and instructions available are for the previous electrical architecture, I'm worried where the line between "settings" and "configuration" lies, as I want to be sure of being able to do the alignment, if needed, and it seems the jury is still out on how to do that without the MDP or Cardaq tools. I'm out in the sticks, so driving 30+ miles to a dealer to have the proxi alignment done (without ABS, etc.) is something I want to plan for, not end up doing because something I though was a simple settings change actually triggers a need for the alignment.

Apologies for the sloppy writing on my part.....

You can read the trucks info all you want through alfa obd but as soon as you want to start tweaking settings and making changes you’re going to have to unlock the sgw with autoauth and any change you make through alfa you’ll need to perform a proxy alignment for, even if you’re just disabling auto start/stop or disabling the 3 honk bs

 

[Jimmy07]

even if you’re just disabling auto start/stop or disabling the 3 honk bs

Just so people know, the auto start/stop setting in the body computer does not disable auto start/stop. I’d hate to see people get alfaobd setup and go through all this for just that setting only to find out it doesn’t do anything.

That, right there, was my worry. Thanks for that info. It appears I'll have to figure out the route forward on the proxy alignment before I can really get stuck in on this....

 

[edder]

Thanks for the suggestions. I’ll try them out. I did change tire circumference.

I tried reverting the 3 changes (tire diameter and front/rear TPMS threshold) I made and re-running proxi alignment to get back to factory state, but I’m still getting the flashing odometer and proxi misalignment error code after this.

There were no interruptions on the proxi alignment process and the truck was in run mode with the engine off and radio on.

Edit: I got it back to a clean state with no errors. From there I tried changing the TPMS thresholds in WiTech2 and nothing showed out of alignment and no DTCs. After that I changed the tire circumference to 2780mm in AlfaOBD, ran ABS initialization in WiTech2, and the proxi alignment started doing the same thing as before with those 4 modules not syncing, odometer flashing, and various proxi related DTCs being thrown.

Edit 2: I reset it back to stock again and started changing 1 thing at a time. it seems to dislike adjusting the tire circumference in AlfaOBD. I have it in a synchronized state with the tire pressures changed from within WiTech, but setting the tire circumference in AlfaOBD seems to make things really unhappy and results in incomplete proxi config alignment (4 modules don’t respond).

I can confirm that WiTech2 is able to change the TPMS thresholds without issue.

So if you just update TPMS threshold in WiTech2 does that require the proxy alignment? I just started getting around to the 25+ vehicles and 1 in particular needs to lower the pressure threshold. Just wanting to clarify before I go guinea pig someone else's truck

That is not a change made by alfaobd, it's an option under misc functions in Witech so no proxi needed. Again please review the alfaobd app to see all available options under body computer. You will not find TPMS pressure threshold in the list for this body computer as viewed as Cherokee WL.

This is an official option under misc functions and not a modification made by alfaobd to the bcm.

This is the only setting in the list that is like that where you can change something useful. Don't expect that there is lots of great stuff to customize in Witech. There isn't. Changing TPMS threshold with Witech was mentioned in this thread several times and is very easy to do. Log into Witech. Go to misc functions and select TPMS pressure threshold and change front and back to whatever you want. It is immediately effective.

A proxi alignment is needed where you modify the BCM as the proxi configuration changes in it the hex code. And all modules on the truck carry a copy of the BCM code and compare it to the BCM to ensure it's the same. When you make a change the copy the modules carry doesn't match the BCM copy and the truck errors out. the prozi alignment copies the bcms copy of the configuration to each of the modules and that makes then aligned as now they all carry the same configuration. If you have more specific questions about this feel free to DM me instead of going back and forth on the thread.

So we’re trying to enable power folding mirrors on a 2026 big horn. We’ve already got all the appropriate parts installed on the truck. I see “power folding mirrors” is an option when in Alfa under the WL Cherokee. Can I simply enable this when connected to the truck and then just have the dealer do the proxy alignment after?

That’s correct

 

[firemedic10584]

That’s correct

Will the function work prior to the proxy alignment? Or does that have to be done in order for the mirrors to begin folding?

I’m not too sure on that one, but let me know if they do.
I do know that when I changed the front fog lamp dropout setting (to have fogs stay on with high beams), that feature worked before a proxy alignment was performed. My thought is that’s because the BCM controls that function, the setting is changed in the BCM, and the other modules don’t care about that, so their proxy doesn’t have to match that setting.

With power fold, the new door modules control that, so the power fold proxy setting might have to be aligned in the door modules also before it will work.

Ok - and just to be clear, when we take the truck to the dealer for the proxy alignment, we're asking them to only do a "proxy alignment" and they will know what that means? I know further back in the post, you said make sure they do not reset the truck to factory settings or something similar?

I spoke to several dealers and the service manager should know what it is. Techs definetly do. Dodge products have been using proxi alignment for years nothing new. What you don't want the tech doing is first restoring module configuration to stock. There is an option for them to restore modules to original configuration. There is also an option to flash update modules to newer versions which would also wipe out the changes you made. In my experience and that of others they don't do module updates unless there is a need to.

I talked to a service manager locally who said np we can do just a proxi alignment 1h labour.

Not all are willing to or very helpful. Best strategy is you already have a relationship with the service team and tell them you just want to add this to your truck will do the configuration change yourself and only need them to perform a proxi alignment nothing else. If they are cool they will agree and charge an hour labour. If they are not they will either refuse or give you run around. Good luck. Hope this helps for now until someone else chimes in.

They definately know what a proxi alignment is it's a common procedure and they also know that they can restore a module to original and update a module.

I would suggest asking for your TPMS pressure settings to be adjusted as you like at same time it's a quick 5 min job while they are in there. I set mine lower to allow more comfortable ride on my non original tires and wheels.

That is something that they can do under misc functions in Witech and should be aware of it.
