Foxflash Failed to OBD Write Ford SID209 Solution

By | October 11, 2023


I have a problem with read ecu SID209 from ford transit 2015
i can read flash and password with foxflash by obd but i have an error when i try to write file by obd?



Iecutool solution:

First read obd password, after that remove ecu and read/write boot mode.


1. Send OBD read data and boot read (full read eeprom/ flash) data to engineer, foxflash team will help modify data, then OBD rewrite.

2. If boot read not working, try to write the OBD read file via OBD on bench mode (using godiag gt100 breakout box), then report the result.
