Question:
I have to read a Citroen C3 1.2 Petrol ECU V56.12 but the wiring connection in Xhorse Multi Prog Boot Mode is missing.
Solution:
Multi Prog does PSA Valeo V56.x in boot mode only.
Here is the boot mode pinout.
If you find the pinout missing, post ECU label and report it to xhorse App, they will send you the pinout.
