Hi,
I cant sync the old volvo v70 2.4t from 2005year.
The diagnistic says 0 KEYS in CEM and ECM-720A error.
This is cem w/o flash! Only EEP 93lc86 and Renesans MCU.
ECU is denso also with eeprom 93c56.
I readed ABS ID nad KEY ID.
Can somebody take a look for files?

Autel, VVDI, Codecard SW cant recognize that dump :(

You have a CEM with serial number 00004ххххх. Read in CEM m32c 30835 and the keys to this car MEG48. And use the right software. https://volvo-fix.com/

You need to read orange5 or xprog original. VVDI will not read it.
