Hello EZS file is damaged or bad read, you have to read it with ETL

[zecas]

wich of the hc08 is bad?
2j74y looks good it gives right km

if 4j74y is bad no point in getting an etl programmer

[DJAMY]

read again with ETL , its the best for this MCU
if you lost files, your situation wil be not fine , you have to :
reprogramm with both good files
renew ESL,
virgin ECU ,
make right KM in EZS and DASH ,
make adaptation with DAS
and start car

[zecas]

yes i need etl for 4y74j for 2y74j no need etl, but car is working because i took ecu ezs, esl & key from other car, now dash display ----- (i did this only for test i need final solution)

could just clone all this from other car but my bigest problem is i dont how to clone key, there is a cheap nec programmer for mb key but is seem it only writes not read old key.

problem n2 : buy etl, buy new freescale, car not work (because maby flash not good), no payment ;)

advices are more then welcome

Can't clone benz key NEC chip, mate.
It's best to generate keys from SKC - ask for help here- and write new key to a NEC chip.

[smayer]

Make a new key a maybe EZS problem is solved. Now you need less then 150km in dash and adapt with Das.

[zecas]

i wil get nec for MB is it possible to get matched dump fore:
key
ecu eeprom,
esl
2x dumps for ezw.

this way no need for DAS , changing km is not a problem done many, never now how to change in assyst but this an another issue

if you unlock the steering lock key and 4j74 is ok
View 2j74 all dump (ETL) is usually broken
