Ford Focus MK1 2002 - Central locking control unit does not lock

Hello everyone. I will stick to the topic if I can. I know that many posts have already been on the forum, but I have to write a new one because the problem is a bit different. Focus 2000 year. Opening and closing the central by turning the key in the driver's door lock works fine, but the problem is The following. Applying ground to the black and green wire at the driver's door opens all the doors, while giving ground to any other wires in this bundle does not close the central lock, so here the matter is by no means strange. Everything is ok when you try to locate the wire in the bundle responsible for closing the door has no effect. Could the comfort module be, so to speak, "released"?

Write if the lock works with the insert?

I wrote that the opening in the driver's door works.

Then find the correct wires in the car's installation for control from the additional controller.
You're probably on the wrong cable.

Remember that you must do these attempts on all closed doors so that all the switches "see" the closed door ....

I plugged in the appropriate cables. I even dismantled the "side" of the door and tried it directly at the driver's door lock and the effect is the same. Black and green opens the locked door, but connecting with mass to any of the wires does not close the central lock. Like clipping into the wires at the driver's side pillar, unfortunately, a strange thing.

I think the mass stays on one of the wires and giving the mass to the other does not work. You probably need to cut the wires and do relay switching. The second is, if I remember correctly, black and orange.

Lock control - in the harness to the driver's door:
black and red, black and green (thin)
downside control

It also seems to me that this is the only way to be done.

I tried in every way and nothing. Only the black and green cable opens. None of the others wants to close the lock.

Defective control switch in the lock. Standard fault in Ford cars. If you cut the control wires in the side of the door and connect the control towards the car, it will work.

The lock was replaced earlier. Unless the second one is damaged. When opening and closing the driver's door with the key, everything works normally (opens and closes).

There may be a second.

So why is it going to be closed and opened centrally through the insert in the driver's door? If it goes to do it, it should open and close after applying the mass to the wires.
