Both Motronic ECUs start out identical, with exactly the same contents and part number. When the system first initializes, the alarm ECU looks for the PIN stored in its memory and compares it to the one in the Motronic ECU. If blank, the PIN is passed over the CAN and written in the Motronic memory.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
