If you select to read the BCM2 with the ABPROG programmer, you need to solder 6 wires on the module’s PCB, and you should temporary remove one resistance (after reading is finished, restore the resistance). There is also a wiring diagram applied. The wiring diagram is located in the program folder too.

If the BCM2 module is read OK, you will see the VIN number, the existing key count and the power class.
