Renault Megane Scenic 1998 2.0 Engine: Persistent ABS Warning Light Despite Sensor Maintenance

I found a lot of topics about ABS, but I did not find what I'm interested in. Applies to the Renault Megane Scenic 1998 engine 2.0
In order to avoid unnecessary advice and questions, I would like to point out that I cleaned all connections on wires and cubes, the continuity of wires is maintained, the sensors have a resistance of >= 1050 ohms. I was with a friend who has a computer for Renault and erased my mistake, but after driving a few kilometers again, the control light came on, the information popped up that there is a problem with the rear sensors, no indication whether it was left or right.
All this failure began when I damaged the rear left brake cylinder, where the replacement of this cylinder could have contributed to this failure?
- soiling the sensor with brake fluid and other dust,
- aeration of the system, although I vented it and braked evenly, I checked the review.
I am asking for advice.

And what exactly did the computer show? Error number?

There was a code, but I do not remember, it was written that the problem with the back, without pointing to the right or left side.

Well, it's a reno comp.

Hm.

So start from this circle

I cleaned the sensors and the rings in both wheels and nothing.
The colleague had an old computer and after connecting it shows the error of the rear wheels and the left rear wheel while driving does not show the speed, you can not delete the error. Does anyone know which pins in the plug of the ABS pump are responsible for which wheels? I want to rule out the lack of continuity of wires to this wheel.

Left front 3 and 18
right front 1 and 17
left rear 14 and 21
right rear 5 and 13

If the sensor does not show speed, and there are no errors at the stop, the options are two:
1. Damaged sensor core
2. Too large distance between the sensor and the polarizing wheel

There are three rows of pins in the plug and they have no descriptions, can you write to your friend how to tell which pin has the number?

Added after 1 [minutes]:

But there is a mistake at the stop and it can not be deleted.

That's why I need pin identification in the plug to check the continuity of the ABS pump.

Undress the plug and you will find descriptions.

Thoroughly check if the abs crown is damaged

Failure removed, the plug in the middle was like new, but the wires reaching it no longer. The break was on the wire to the left rear wheel.
