HI!
I installed used DME with MSV80.1, then I read ISN from DME and write it to CAS3 (0L15Y), BUT car doesn't start and here DTC DME: 2F49 - Immobilizer anti-tampering protection and DTC CAS: A102 - Immobilizer anti-tampering protection. PS Vin at DME I change also. PLEASE CAN HELP ME DECIDE WHAT IS PROBLEM?

DME ISN written plaintext to the CAS. When the CAS "decrypts" it for use the resulting string won't match the DME's. Post the info of the key you're using; transponder and remote information, that is.

In Abrites Tag Tool, enter the following SK low and SK high in the right top parameter section and read again:
SK low = b19f67ac
SK high = d486
Please post a more readable screenshot...

Also enter the SK as shown in the top right parameter section and read the same key again.

But this CAS has long ISN, so how can you synchronize it
