To adapt a module to a Mercedes truck, you need to make it virgin first, which requires a service password that is automatically calculated when you press the “Virgin” button. After that, you can personalize it using the FBS data from either the replacement module (ECU-ECU or TCU-TCU) or the EIS/EZS.

The final step in exchanging any DAS unit is to press the “Activate” button, which confirms to the vehicle that the operations you have performed need to be saved.
