Vida CEM swapping

[vtl]

Really interesting how there is absolutely zero information about that anywhere that I found (before now lol) so a big thank you!

That's not entirely true. If you read all 438 pages of this thread carefully, you may even find the answer to the ultimate question of life, the universe, and everything.

It at least seems like I got the CEM PIN anyways, so is there any better way to check that it is the correct one?

Send a CAN message with unlock request if you are bored. Buy a feature in VDASH if you are rich. Drink a beer otherwise, your pin worked.

That's probably true actually, congrats on page 439 btw

Now before I did anything else I put in my PIN and backed up all my modules through VDash, but I can't figure out where the backups actually go, so it seems that they're stored in the cloud on their servers.

And also thanks for the help, probably gets boring to answer these types of questions the 100th time and beyond lol

If OpenMoose finds pin on CEM B it is correct, the check pin does not work on that CEM model

[the check pin does not work on that CEM model

Well there we go, glad to know I wasn't the only one doing something wrong lol

Also how did you know that if I can ask?

Look in the about page on the OM app and you'll see my name

I have bench setup for P2 cars so i have tested almost every function

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 value - engine will not start. It will crank but no run

That is what I mean :

Hello mates,

I've succesfully decrypted another CEM L on bench. Make a clone with ioterminal.

When i plug the new CEM the odometer does not work. The car starts but non odometer.

Any ideas ?

So will this work on a Volvo xc90 t6 2004

Built the teensy decoder. Connected it to the vehicle. Run software. When looking at the log it sends the LS can command. Cant find cem part # on ls can but it finds it on hs can. Shows it finding the part number. Puts vehicle into programming mode. Whole vehicle shuts down as expected. Starts the counter. Ends up going to 99 0 latency. Reboots vehicle then says cant find cem part number. Tried three different kinds of canbus modules like waveshare etc. checked wiring and diagram multiple times. Added in 12v converter to power externally didnt change anything. Adding and removing grounds didn't change anything.
