Me7.4.5 Pinout -

To put the ME7.4.5 into Boot Mode (required for full reading/writing of the internal flash), you typically need to modify the circuit board slightly before connecting your programmer (like Kess, Galletto, or Piasini). Add Resistors : Solder two 6.8k Ohm (6k8) resistors to the designated boot points on the PCB. Remove Resistor

: Manages power distribution, main relay control (Pin C9), and communication lines with the BSI (CAN/K-line).
