Yesterday (13-09-2019) I was able to test by disconnecting cables for the coil driver binary outputs. They were incorrectly connected indeed and I fixed them.
Very likely the information will not be useful in the future but I write here how they were connected, just in case:
Coil driver ⇒ MEDM screen indicator
GAS ⇒ IP
IP ⇒ TM
IM-H ⇒ IM-V
IM-V ⇒ IM-H
TM ⇒ GAS
