Vida CEM swapping

[dikidera]

I believe J2534-2 is an extension to allow communication with more modules.
Here are some sections marked with J2524-2
https://github.com/diamondman/J2534-Pas ... 34_v0404.h

DiCE J2534 help file can also be useful.
J2534.zip


Some history and revisions:
https://www.kvaser.com/developer-blog/s ... on-part-1/

The help file seems to be missing the actual articles outlined before. I have vida installed, but couldn't find these help files in C:/Vida.

The help file is from the DiCE folder, not Vida.
Maybe not included in all versions.
Some lacks the flight recorder also.
And some has a J2534Tst application.

Ah I see it's part of the "drivers" for DiCE, the device.

Good evening.
I have been for a cheap but effective way to unlock my cem pin through the obd2 port
I found the teensy 4.0 method but I'm having a hard time finding parts.
I found a pcb file which has all the wiring for the pcb as well.
However, I cannot find the bosch cf160 transceivers needed for the job.
Also, in the schematic on github, I can see that some resistors that need installing, but I'm not sure where to install them on the pcb.
The pcb link:

The github link: https://github.com/vtl/volvo-cem-cracker

This one should have the can side of the components if i am not mistaken

Goodluck

The final piece of the puzzle is to make my Python wrapper aware of baud rates which will also automatically handle pin switching, however there are some things which bother me.

Filters, timeouts, inrush messages saturating all rx buffers in our DLL...

Mind sharing pictures of your hardware?

When I first started working on cracking my 2005 XC90 I would see all the zeros if I tried cracking with the key in position 2. If I left the key in position 1, or not use the key at all, it would crack the PIN just fine

Goodluck

So, with these, I don’t need the resistors

If you look at the board in this link : https://www.waveshare.com/sn65hvd230-can-board.htm You can see there is a small 10 k resistor on the board next to the chip on the side of the board, at the top were the screws are there is a jumper which connect the 120 k resistor which is used if you have your unit on a bench and not in your car.

I myself used 2 of these with a teensy 4.1 on a breadboard you could also use a teensy 4.0 does not matter
