Retrofit Adaptive Cruise 2025 XLT

[rusty_shackleford]

The CCM wiring into the IPMA for pins 9,18,19,20 also match what F150/Lightning trucks have:

So either Forscan for 2025 Maverick can't show the CCM or maybe another change is required in another module before it can show up.

Interesting reads, thanks for sharing. I made an attempt to translate that guys spreadsheets to my Mav, using the lariat asbuilt as a reference, and no luck with just IPMA edits. I’ll try some of the other modules later on today.

I’m wondering if Havemav and I just have terrible luck and both have dead CCM , or the firmware is too far out of date to connect with the IPMA

I've attached all the differences between my XL asbuilt and what I could find for two different lariat vins online. 3FTTW8S30SRA97852 and 3FTTW8S37SRA85648 are green and pink in the list.

Does anyone smarter than me see anything that might be important to activating the CCM thats different from past attempts?

A distinct possibility is that the canbus communication is now encrypted and you won't be able to do it ever.

19-01 to 19-04 is your Vin in hex. I am with Colinl, it may be encrypted or such thing so farscan is not smart enough to read modules.

Jesse-Infotainment seems to be the IPMA expert over at F150 forums and that you found the post on Adding ACC/LKA on TRON CANBUS, so maybe can get this problem figured out.

Hmm, might have to get the console hackers or foone or someone interested. There are sometimes ways to glitch things and make them give up keys.

I highly doubt that considering that Ford almost certainly encrypted it against theft moreso than owner tweaking/tampering.

canbus is how the engine immobilizer signals that it's ok to start the vehicle, the telemetry unit talks to the body module to unlock doors via fordpass, and so on.

this is, of course, just speculation. it could be that the russians who make forscan will figure out how to talk to the modules and enable the ccm calibration and other functions that we have available in the 22-24 mavericks.

I guess keep an eye on whether "the pros" can do it. Like Fortin who had canbus interceptors for remote start and tracking apps, looking at their Ford applications, seems they haven't figured out 2025 yet, but it might be a watch this space thing...

Which might mean one then needs to buy one of their modules, or figure out how they did it.

So correct me if I'm wrong but both of you who have tried this so far used CCM modules from older vehicles?. They COULD be the same but the 2025 Maverick CCM uses a different part number and since it's connected to a totally different type of IPMA than the older ones were, there is a chance the problem is the CCM that you are using. Just a thought....
Also, the bus between the IPMA and CCM is NOT encrypted. Only the main modules such as IPC/PCM/TCM, etc communicate via encrypted buss. This is to prevent theft and hacking via OTA via the TCU or by cutting into can wires and such. The CCM is tied directly to the IPMA and no other modules are in between.
There is a chance the lower level IPMA just doesn't support ACC. Might have to have the Lariat one, which is a different part. Ford is getting more and more like Honda and cutting every little corner they can when it comes to modules and wiring harnesses.

Your theory could be correct or the issue is Forscan. Just today I received the 2.67 test release from Forscan for IPMA calibration. It could be I will be able to discover CCM with this version. I will test out. I broke my connector so I am waiting for my new connectors to be delivered.

This is what I was thinking. Tried to save a buck and get a different module, there’s a chance we need a brand new module to see success.

2.67 test release

How would I acquire this? I can test tonight if you can share, I paid for a year license and have beta access but didn’t see anything about a test release on the forscan website/forum.

Here is the link

https://forscan.org/download/FORScanSetup2.3.67.test20250621.exe

I already calibrated so it works it is just that it doesn’t let you know when it is done. Run for 15 minutes and stop the calibration, it says ‘success!’

See if you able to see CCM with this version.

No changes here. Thanks for the link.

Thanks for looking for. If you have a paid Forscan I would say save a debug file as said in the link below and send to Forscan to look for potential issues of not detecting CCM while trying to retrofit. If its on Forscan they will work on test build and let you know. That is how I got calibration worked.

Per jesse-infotainment at the f150 lightning forums, our IPMA versions might be the issue. This may not be possible to overcome, unless someone figures out how to get lariat tron modules working in another trim. What I’m wondering is, is it really a hard thing to do? Or has it just not been tried yet because it’s expensive if you’re wrong?
