I used ioterminal too and confirm the replacement cloned fine.

The two CEM-L I have been using both seem to stay ready to communicate whenever. In the vehicle I could just connect and the programme would start identify and run without any ignition key input and even with the door switch state not changing. I know some vehicles wake the CAN up as soon as a door ...

Interesting to see what it's doing.
With those 120ohm resistors in place the CAN signal looks pretty good at approx the correct voltages.

Update: The transceivers I ordered finally arrived yesterday and I managed to have another try this morning. Both CEM cracked successfully using HS and LS CAN both connected on the vehicle and just HS on the bench (with the 120 ohm resistors still fitted to the transceiver board for CAN (which I was...

Hello, Sorry for the stupid question . I’ve read through the whole thread with great interest and thought I’d try giving it a go and try cracking a CEM L on an xc70. My first mistake is probably that I should have bought a Teensy 4.0 instead of a 4.1 I thought that it would work, but am very new to ...
