Ren Master II no door lock

[alessioblaupunkt]

Diz Reno Master of Puppest enter in the garage often, this time for central unoperative locking.

You turn the key in every of the three door and you lock or unlock THAT door.
You press the button inside the cabin and the van CORRECTLY lock or unlock ALL the three door.

If you disconnect the driver's door lock unit and check the voltage, you turn the key
in the passenger's door and in the driver's connector there is voltage for lock and in the other
wire there is voltage to unlock.

If you connect the driver's door lock unit and check the voltage, you turn the key
in the passenger's door and in the driver's connector there is NO voltage for lock or unlock.

Under the dash, if you ground the orange wire of the locking unit, you unlock ALL the doors.
if you ground the ? wire of the locking unit, you lock ALL the doors.

So if you have an idea of what is not working please help.

The old good method win.
Can't be economical and faster.
After spending hours thinking of "the locking control unit is ok and so are the door lock unit"
I opened the remote control and investigate.

And solder.

And win.

Another (will be) happy customer, but for now I'm down with the other 3 major faults.
