Volvo V50 1.6 EDC16C34 - Error Code 7700

**aqua_life** · 21st May, 2020, 07:14 PM

Hello,
Volvo V50 1.6 with ECU 0281011775
Car has error Engine ECU 7700 seems like a checksum error or ECU error.
Then also ABS error 0101 no communication with engine ECU
Engine light is OFF, Anti squid light is ON and message on dash.

This problem seems usual on these cars but can´t understand how to solve it.
I bought another used ECU, cloned it and the problem is the same.

Then I saw a Flash file here on DK very different than my file for the same ECU.
So, I write this file and test on car. Exactly same problem.

Someone has a solution for this ?
Attached Flash ORI + eeprom ORI + Flash file I tried from forum.

Thanks for your help
