Skoda Octavia lift - Driver's door control module too low power

Hello, the problem is as follows: some time ago the central locking started to freak out, it closed, it opened when he wanted to, additionally the indicator light was on informing about the open driver's door. The first lead on the bank is the lock, the limit switch. I undressed the door, fastened a new lock and no change here, then the same. I connect the computer error 01331 driver's door control module (j386) too low power supply. There are two power supplies and after checking with a 12.4V meter on each, probably correct, after starting the car 14.2V. Weight ok, still the same error. I will add that pressing the buttons on the windows or mirrors sometimes works properly and sometimes they close and open the car, a bit strange. Whether the driver's door module or the comfort module should be to blame, I checked the cables, they are ok, unless I don't know about some, I will be grateful for your help.

Check the wires in the passage to the door, maybe they are frayed, check if everything works properly when closing the key, sometimes it happens that the insert in the door is jammed and the comfort module stupid and, for example, closing the opening with the remote control does not work. . Also check whether water accidentally got into the comfort module.

all wires ok, all the way to the plug at the bottom of the threshold, the lock is pulled out, closing the key does not work, I hooked up a new lock, no effect, the remote control works to open all doors, close all except the driver, dry module

This remains the module in the windshield drive.

Check this power supply, mass and plus a 55W bulb.

Anyone from colleagues has a description of the pins in this module ?? because from what I have come there are 2 pluses 12v, one 4.5V and two masses, I do not know if there should be a plus because I can not find the description of the cube anywhere ....

There are only 2 in the Passat, as you write, from the module in the door to comfort, everything is cheap.

Ground pin 10, brown.
Plus pin 19, red and yellow, and pin 20, red and white.
Measure power under load.

19 and 20 pin 12.4V power supply, after starting the car, turning on the radio lights and 14V air conditioning, I'm thinking about cutting it and checking the solders, in b5 you can remove the electronics in Octavia, you can not take it out, I have such a module from 99. with Octavia, but it differs with the electronics board and when I hook it up, 3 other errors pop up, so I think I have to have the same as mine, it's hard to find them ...

Did you load the circuit?

the error pops up immediately after turning the ignition on, after deleting the correct voltage pops up again
