yeah i noticed, but i also have the same issue and cant seem to figure out how to fix it....
thought to confirm if he fixed...
Usually VIN not identified is an issue talking from the IQ to the BCM.
If it's not correctly coded in that will happen and also if the BCM is starting to play it up it will happen, My factory series II did it when the BCM started to play up and dropped the link betweeen the two modules.
If it's a fresh conversion and you haven't coded the IQ to the BCM that will be the problem too. On VE's pretty much no modules are plug and play, everything has to be linked through the CANBUS network.
Best bet is to find someone with a Tech2 unit who can scan the IQ system and BCM for codes and it should log where the connectivity issue is.
