Renault Laguna 1 '95 2.0 16V: SERV Light & Emergency Mode in Intelligent Automatic Gearbox

Hello, I have a little problem with my Lagoon I, because sometimes the SERV light comes on, it does not cause much of a problem for me because there are no lights other than it, but my Renault is equipped with "intelligent automatic gearbox" and after turning on this indicators, the car goes into emergency mode and does not change gears as it should, it works in low gears, which requires higher engine revolutions while driving. This morning, after starting the car, the light came on, after taking about 25 km, I returned home, opened the hood and "fumbled" in the box marked (attachment), because this light came on while driving, but it went out after restarting the engine, but SERV was on fire still. After my treatments, after returning SERV, it went out, but these lights do not always flash together, what could be the reason?

What errors are reported by the engine controller?

after starting the engine, my dashboard looks as follows, as you can see, the SERV went out, but sometimes it appears at the least expected moment.

I meant computer diagnostics.

I cannot find the plug for connecting the diagnostic device, I know that theoretically it should be under the steering column, but I cannot locate it.

Under the hood, so square.

all in all yes, excuse me, I forgot to ask "uncle" about all this.
Only now I have to find someone with a computer, the only problem is that the light comes on once in a while and when I go to the mechanic and the light goes out, the computer may not show me anything ...

He will remember the error. Do not disconnect the battery.
