Problem:

Xhorse Multi Prog failed to read Renault/Dacia EMS3125 ECU. After connecting, the program reads the processor identification but does not read the content. The software reported a chip data reading failed error.

Solution:

As the multiprog said, the chip is encrypted and cannot be read.
The processor is password-protected.

Xhorse multiprog cannot read this; boot mode only combiloader, obdstar or trasdata.
