MJD 9DF boot schematic

[byati]

While writing Fiat Tipo MJ 9DF ecu from OBD (with Flex), the flash is broken. He no longer sees the brain from the flex bench and obd. Does anyone have a boot connection diagram for the IO terminal for this ECU. Or how do I restore this ecu?

I/O terminal can't do bdm for Marelli ECUs, only bench mode.
You can try to connect it on bench with I/O terminal diagram (on their website) and try to click on 'Read ECU info' to trying ecu identification, or select MJD9DF and try to connect..
If bench of I/O terminal doesn't work you have to open the ECU and do it in bdm, for this you need Bdm license on Flex or an original K-Tag...

yes, ioterminal on this ecu only service mode...

it´s hard to open this ecu...
if you handle it to open (both sides)...
you can read it in circuit...
MM FLS0.4 you need to have as module...
