Foxflash Failed to Read Fiat MJD 8F on Bench Solution

By | May 9, 2023

Problem:

I failed to read Fiat Ducato Marelli MJD 8F IAW ecu with the foxflash programmer on bench. It reads ID but failed to read data (error boot1). Any advice?

Foxflash Read Fiat Mjd8f 3

Solution:

Foxflash will read and write Marelli MJD8F full system. It will read the whole backup.

DON’T CONNECT BENCH BOX WHEN READ THIS ECU.

You can also read and write with foxflash in jtag mode.
