Clear as mud, yes.

It'd make sense fit the IHU to initiate the check, wouldn't it? It could be off at start time.

Seth, I suspect it's stored on an eeprom in the IHU, but every time I've torn one down, nothing jumps out.  Oh hang on, if I trace the canbus +- through, I'll find a likely location.  I wonder if it would be possible to write the vin back to the rom by sniffing what a TechII does? Bound to be some random checksum nonsense in there like Karlis found....;)

I'll give it some thought and have a mooch at Tomi's site
