Any idea why the car wont start. It is a volvo v70 2002 d5, all keys lost. Add the key using org carprog, no start. Vida shows immo status - start not permitted, the car dont see transponder at all. Synchro with ecu - sometimes positive, sometimes negative. Took cem to pro key maker, he did two other new transponders and same, wont start. Vida shows that ID from cem received, but still doesnt see transponder, start not permitted. i tryied to do "restore cem data" using synchronization utility, still same errors. Vida as well shows wrong transponder error. transponder is original ID48 megamos non locked, tryied 3 new transponders. Other thing, when reading cem pulled out of the car, cem info is different from what i wrote in to it. Damaged CEM module? tryied to swap antenna ring, still doesnt work, checked all signals according to Vida, all good.

Not correct information! All black blocks are not CEMs, but REMs (Rear Electronic Module)!!!!

Hi .
I asked the question if it could be done.
The car is far away, you have to go there for over 90KM.
I have to go read ECU AND CEM.
Hence my question is whether it can be done 100% sure
Is the ABS ID also needed?
