Re: Vida CEM swapping (2008 C30)


Hi everyone,
First, I have to thank you for such a fantastic project. It's cool that you can get a PIN code without disassembling anything and sending CEM, in my case probably abroad.
I have assembled the project with the use of a breadboard for my 2008 C30 (CEM P/N 31254903).
Unfortunately, I ...

Re: Vida CEM swapping





Do you have 120 Ohm terminating resistors in your CAN shields? They must be disconnected when cracking in car.

Yup, I had them on the board initially, I unsoldered them for the in-car crack, now I'll solder them back again and give it a try.
Just took the CEM out of the car.
Looking into ...

Re: Vida CEM swapping



No luck with either of the options. `cem_freq_align` showed a bigger latency difference between the pins, but still didn't work.
I think I'll take the CEM out and run it on the bench. I probably should have started with a programmer in the first place :-)

Do you have 120 Ohm terminating ...

Re: Vida CEM swapping



Ok, I tried clocking my Teensy back to 600MHz and it didn't help. I also tried manually brute forcing the top 6 pin candidates by latency from the last round (byte 3), also no luck. It seems the only option for me is a 20h brute force of the last 4 bytes.
Will try as soon as I find a place with ...

Re: Vida CEM swapping


Hi all, thank you for creating this project, it's amazing! I've been monitoring it for a while but today I finally got my Teensy-powered breadboard assembled and I run it on my car. Unfortunately I got "PIN is NOT cracked" message at the end and I'm a bit puzzled what to do next. Any ...
