Problem:
When i do Fiat MJD9DF with foxflash over bench I have a problem with write- error full system locked. i have read bench file and modify file, when i need write it back, say me “locked”. Is it possible write over obd or when i try jtag mode will be unlocked?
Solution:
Read what say your tool “USE OBD DRIVER”
Sure your ecu have sw 4L43 or hw001 or hw002, so the only way for write these ecu is by use obd driver, not bench driver.
i.e
i made last week Foat ducato 2018 with same ecu i read on bench to avoid voltage problems because if the vehicle is 2018+ you will have slow reading, i read on bench about 2 hrs and modify file i was not able to write on bench so i make on obd without problem write time was 7 min, and on kt200 or foxflash sw is same. read injector codes in case its lost during programming.
Or open ECU, do it via Jtag boot mode.
Jtag is safe.
Done many with foxflash.
If do it with fox flash in jtag mode, check Jtag pinouts here
