Because the readings for various functions are written to a flash rom and the rom needs to be blanked by a specific command/routine. Out of interest to you cossie boys, The P8 is the same.
So when you key-on and the ECU see's a particular pin high/low (thanks to removing the fuse), it branches out and performs some erasing sub?
