Question:
I tried to read Ford Focus 2010 euro 4 edc16c34 with foxflash via obd. It says ‘Danger blocking in writing’. Will foxflash do this ecu via OBD?
Here is the clue.
Bench is the best.
Pcm flash original read/write full bench edc16. Never have any problems with it. Foxflash also good for edc16 bench.
Ford edc16c34 up to 2008 ok obd with a lot of tools if you follow instructions, 2008-2010 bench only.
It’s same issue with all tools on market. There are 2 C34 versions: hw C34-2x and C34-5x.
If it’s 5x, it have another type of flash inside, and you need to bench/bdm it.
Feedback:
Focus 2010 euro 4 (as euro 5 is sid807evo) tested almost all cheap tools obd, reads ok, writes up to 100% but it fails to wake up ecu from programming mode (some thing like that). Writes back ori file good. bench is best, foxflash obd was tested just for education only.
