Are You desolder flash or OBD read ?
Can You connect on ECU with ORI flash ?
Are You check ECM relay ?

Boot mode for EDC15c7 ???...its ancient way....are you removed boot connection before diag connect ?

Pinout with FGTechnology genuine

Use any diagnostic tool and try to connect to ECU on the table (bench)
...look on mA..its should be around 180mA.
If its ok try to connect diag in generic mode.

Sorry for late reply
I checked ECM relay, OBD power fuse, etc all OK
Still no comms on obd

Pinout on bench
Diagnostics connects and reads dtcs
FGTechnology genuine does
Kess does not. Change of session not possible

So stumped as ecu looks good as does immo

Bang on 150ma too
