Hi
I have problem with boot mode Galletto V54 , ECU Bosch 0 281 011 084 I can't read memory. I have pin connect and short pin 24 to ground and nothing . I connect
+12V to pins D4,M1
ground to pin M4,
K-line pin B1
If I read can 29F400 I make immo off ?

Power supply for the ECU, and PC power from the network ~ 220 may have problems with grounding? Take the laptop to work on the battery.
