mercedes ml320 ecu locked

[peter006]

friends.... i have question....
98 ml320, i got new aam(used) and i transfer dump from eeprom of mcu from the old aam to new aam....
yes... security is accepted 100% now.

car does not start, appears because in scanner i see:
ECM STATUS: LOCKED

the question is.... if i transferred whole eeprom from old original mcu to new aam mcu, how can pcm see its a new different one? there is some other place in amm where it's id is stored i can transfer to new aam so pcm accept it?

In das i do not see any option to adapt them together...
:hmmmm:

You need check number of AAM or see necessary number in EPC. If it different, AAM can dont work, becose in 1998-1999 MB change DAS2 system (after 1998 ML have AAM and EAM)
may be its trable

part number is correct 100% match, i think the problem is that now they are not "married" together, only i do not see why this could happen, since eeprom is copied over to the new one...
