Hi everyone!
I would like to ask a few question maybe someone can help me.

The problem is:
I bought a LEFT HAND DRIVE Ford Focus 2010 with a door lock problem.
The door continuously locking and unlocking by itself.
When i pull off the connector from passenger's door control unit the self lock-unlock is stops.
BUT when the connector is plugged in,i can not lock the door via keys,remote and the passenger's door functions are not working.
Like power windows,power door locks,mirror adjusting.
And i can not control the passenger's power windows,
the rear passenger's side power windows and passenger's door mirror from the driver's door switch block.

Now i think i found the problem.
I don't know why but maybe someone replaced the passenger's door control unit to a second hand unit.
BUT maybe that person is bought a module from England because if i tried to read the fault codes i can not read the door control modules when passenger's module was plugged in.
After that i pulled of the connector and i can read the driver door module and everything looks okay.
But if i pull off the driver's door module and I plug in the passenger's after that i see in the diagnostic tool shows the passenger's door module like driver's door module.
And it contains fault code like "communication fault with switch block"
And if i read live data like door lock switches,or any state of live data,it shows driver's door control module.

It is possible?
I mean, it is possible to 2 driver door modules was built in 1 car originally?
Because i read out the car's configuration and it shows only the driver's side door module ( DFDU )
There is no passenger's side door module in the configuration. ( PDFU )

Is there any way to code/configure the GEM module (or what ever stored the config) to see again the driver's door module?
Or i never will see in the "built-in"control unit list?

Is there any way to make/code/flashing/configuring a driver's door control unit to passenger's door unit wiht any software?
Because i bought the same part number door contol unit like the "original passenger's module was" from Ireland, BUT i think i did a mistake because the front right side door at Ireland is the driver's door.
So now ,i must buy from an European car's right front door control unit? Or is there any way to coding/configuring/flashing this module to drivers's side?

Please help me!

If someone run into this same problem, the solution was: I bought a second hand door module for passenger side door.
The problem was inside the door modules software. For some reason the door module "switched itself" to think it is a master door module, and it was acting like a master door module. When i bought the passenger door module,i read out the software from second hand module and from the original too. I compared them and the difference was only one byte. Some reason (maybe a flat battery) that one byte switched, and after that the passenger door module was acting like a driver door module. So there was no option in Forscan or OEM Ford diagnostic, to code the module to passenger or driver side module.
Ford produce these modules with a different label and part number depend on what side is. But inside the software is the same. So one byte in the software decides what side is these modules....
