Maybe I'm not on time))) But why don't you try to subtract microcontrollers using Xprog? I had the same story and I calmly read them on the table. I cut off the burnt part of the printed circuit board.IMG20260511123358.jpgIMG_20260511_124619.jpg

Of course, I started by trying to clone the two ...

Yes there is the problemTo the CEM with a Xprog
ECM i do nothing

the synchro is problaby not matching in the ecm. Take a backup and check it. Did you correct the checksums ass wel


I simply took the .bin file and loaded it using my Xprog.

What is the correct procedure?
How do I verify the ...

Yes, I even tested an XT27.

And you have written the pages in correct order?

I think, i tested the 2 order

I assume you have unlocked the chip correctly
Maybe not :roll:

And you have flashed the CEM and ECM with the new files?

Then you need to program new keys to CEM if you don't have old data available.

Yes, I did that with a Xhorse MiniKey and a brand new ID48.
I copied the CryptoKey into the ID48 and entered the ID48 number into the synchronization software.

But the car doesn't recognize the key. I'm stuck ...

Just sync CEM to ECM if replacing ECM


Either I wasn't awake or the translator reversed the letters.

But it's definitely CEM that I replaced. :lol: :lol:

I'm having the same problem on my V50 T5.
The ECM is completely fried.
I'm trying to reconfigure an ECM, but I'm stuck on the key learning process.
The ID48 is never recognized by the ECM despite using the ME9.0 Synchronization Utility software

i know that i can use the VolvoSynchro V1.4 to get my cem aligned with my ECM

VolvoSynchro ver1.4 doesn't work. It can set 10 synchronization bytes, but doesn't give You the eleventh byte,
which together with 10 synchronization bytes allows to start the engine.
Without correct 11th byte ...
