When attempting to read a Lancia Ypsilon Marelli 6JF ECU using the Xhorse Multi-Prog in bench mode, some users may encounter the following error message:
“Chip power configuration modified failed! Error code: 87038009 Please use the 12.0V power adapter!”
This issue often causes confusion, as it appears to be a hardware or software malfunction. However, the solution is much simpler.
Cause of the Problem
The Xhorse Multi Prog device is shipped with a 15V power supply by default. While this works for many ECUs, the Marelli 6JF ECU requires a stable 12V supply to operate correctly. Using 15V prevents proper initialization of the ECU, which leads to the failed connection and error message.
Solution
To resolve this issue:
-
Use a 12V Power Supply – Replace the default 15V adapter with a reliable 12V power source.
-
Check Connection Instructions – Ensure that all wiring follows the Multi Prog bench connection guide.
-
Retry the Reading – Once powered with 12V, the Multi Prog should successfully communicate with the ECU and allow you to read data without error.
Final Note
This is a common pitfall when working with certain ECUs that are sensitive to voltage requirements. Always verify the correct power supply specifications before attempting ECU communication. By simply switching to a 12V supply, the Xhorse Multi Prog Programmer can read the Marelli 6JF ECU on bench mode without issues.
