FGTech Galletto 3 V.53 - strange bug on bdm

[ross79ta]

Hello folks, I'm here to ask help for a strange "problem" I have using my FGTech Galletto 3 V.53 as BDM: when I turn on power on ecu and click "connect" button, with every kind of ecu, at first try the sw returns an error and suggests to turn off power for 10 seconds and re-try. I did several attempts with professional bench power supply and I see that when i turn on the power supply, without giving power on ecu, the ammeter reads 0, but when I turn on the ecu, the ammeter reads 0,30A. After clicking "connect" button and turn off ecu, when I give power again, the ammeter reads 0,14A and then the tool/sw can read/write ecu.


I have also a V.48 and I did same tests. It doesn't any problem with BDM and i read to the ammeter a constant value of 0,17A when i connect tool to power supply, and the same value when i give power to ecu.


Someone can help me to find the problem?


Thank you in advance.

try putting the adapter on v48 to v53

Is not the adapter. I also tried with a cable self-made which I can use cmd adapters. It's an hw problem, I'm sure...
