Cheksum Error KessV2 *Need Help

[MResat66]

Hello, im new in this. I have an PCMTuner and a china KessV2.
I tryed to read/write a 2014 Ford Fiesta ST 180hp. PCM cant read or write. Not on Bench (Module71) and not on OBD (Module 5+6+7).

KessV2 readed, but gave an "Cheksum Error" at end from Reading. And when i wanted to write, it gave the same Error and did nothing ...

Do you have a Solution for me?

Thanks to all

Im Not Sure, I have a picture of the ECU... Kess says MED17.2
ECU1005113

i am pretty sure you use wrong pinout for 71 module in pcm flash clone.
try this one:

Bis jetzt hatte ich allerdings keine Probleme mit dem Gerät oder dem Computer.. also .net Framework usw. Aber ich werde es mal probieren!
Ich glaube auf Bench hatte ich die gleiche Pinbelegung, soweit ich mich erinnere

how you can connect wrong pinout if med17.0.1,17.0.7 and m17.2 have same connection for bench mode?

I think, rather, that there is problem with cable or some problem with hardware of the tool.

checksum problem on kess is almost always software problem

I Checked the wireng 3-4 Times, It was like in PCMTuner Software showen.

@carmageddon: Do you mean the Kess Software? I have 2.8. But on other Cars it worked nice ...

Could be kess issue or "corrupted" flash by a previewous tuning made by obd. I did the same ecu with ktag and all went good.
Pcm sm2 pro did not read eeprom(read blank eeprom) so i have used ktag and did it ok.
