Fiat Ducato Marelli 9DF HW001 bricked
Hi,
We have received in the workshop a Marelli 9DF HW001 ECU that was bricked while flashing with another tool. Flashing was not finished and we suspect the ECU is still locked in writing mode by eeprom or eeprom is corrupt. There is no comunication with ECU by OBD or BENCH (we were able to read in boot both EEPROM and FLASH). We write back the original FLASH but no progress, no communication to ECU after. We tested the ECU by flashing a random EEPROM from another Ducato HW000 and the ECU is back alive and comunicating over CAN, confirming the issue is the eeprom. Any ideas how to recover this? We tried FLEX bench, FGTechnology bench, Autotuner bench. Fiat Ducato 2.3D 2019 MJ9DF HW001 52127147 52174569 52128407 ZFA25000002M49081 D120A834 |
