Hi mates,

I received two ECU from same costumer, from "what i´ve been told" both died few days after flashing NLS/LC.

Not a big problem, i thought, but:

K-line - No communication
Boot mode - Only C167 detected, no memories available.

I suspect of damaged flash/eprom, but, even after changing them to new ones, i cannot get any communication.

Flash has vdd/vss/CE...etc...

I already tried different tools to boot, no success. (VF2 Flasher, Original MPPS, China Galletto, etc..)


Any clues?
Any advice?

Ditch NLS/NC until you find someone who can code it for you properly.

You could also disable RSA checking.

It´s not my job, costumer sent ecu´s to solve the problem, i didnt upload any file on it, just helping to solve. And because costumer said it was after fews days runing LC/NLS, i remembered this board Smiley

What are you asking? What sort of solution are you expecting?
You have 3 options:
1) remove NLS/LC
2) disable RSA
3) find somebody who knows how to implement NLS/LC w/o stomping on the RSA functions.

If bootmode isn't working the ECU is fried or your bootmode method is no good.

Does it work on other ECUs with the same PN?

At the moment flash is original, i only need to get the ecu to communicate. I don´t need any LC.

ECU goes into boot, i can connect to processor, but i never have memories identified (neither flash or epp), that i already tested outside board.

Can you read eeprom in boot mode?
