Purpose: to replace a steering column module, so need to pull the info from the old module and dump it on a new one. The replacement module im using is used. Do i need to try and virginize it?
Device to use:
Question: I'm having an issue when im trying to read the old chip. The scanner comes up and says chip unlocked failed.
How-to do next?
you read EPROM from the old module and save reading and then write that reading in the new module and also from the new you save a backup.
2.Autel can do with xp400 programmer, Doubles check picture, in XP400 we have 2 picture for this ezs,. Did you try to use both ?
Read mcu with programer and write data to secondhand.
Need to make sure the mask set is the same.
And yes: Always Virginize if replacing things
If you adapt used without write data you odis online or buy emulator by xhorse.
