2008 - BRAKE, ABS, VSC and Orange Circle with Triangle light on, with steady beep

Some systems begin to come into operation as soon as you open the car door, so the ECU will have time to detect a low voltage error before you turn on the START button. The converter is quite reliable during operation. When it burns out, then this is a specific failure, and there will no longer be 13-14V in the system.

 

Here is a picture I took while this was going on . Cheap obd2 reader didn’t show any engine codes.

Let's assume that this is some kind of defect in the connection and contacts 1(3E) - 1(B) AMD

 

Is this something easily accessible for a newbie?

 

The converter is located in the inverter housing at the bottom.
The relay unit is a large black box with fuses and relays under the hood.
Auto electrician skills are necessary. Without experience, of course, it is difficult.
