Renault Delphi DCM 3.4 with Kess V2

Postby gsa50 » Fri Mar 11, 2016 2:03 pm

Hello everybody!

Me and my friends bought a Kess V2 Master to tune our own cars... Today we tried to read the ecu of a Renault Megane III 1.5 dci 90 hp (Delphi DCM 3.4) with card system. The reading starts but by (about) 15 % there is an an errer (error in reading/data connection). The car is listed in the Kess protocols...

Do you have any idea to solve that problem?

Thanks for your help!


Stefan

Did u use an original unit or a chinese one?
If u had a chinese one, you should rework the pcb to make it "better".

Anyways did you use another battery connected to the car? Is important not to let the voltage go down during a reading/writing process.

You must turn on the ignition correctly.

first--put the card to the car. so the ignition is open automaticly. Then press the start button about 30seconds. The car will say ''take the card'' . So with this way the ignition will not turn off automaticly. You can read the ecu..
