If the lights turn out when the doors are opened in the passenger compartment, you need to check the position of the power-off switch: the light may be off completely. If the lever is in the right position, the fuses and trailers must be checked in the doors. If everything is normal, the problem is likely to be in the control unit of the ETACS car. He's behind the fuse box at the salon. You can see it on the right side of the transistor K2415. It should be replaced by a similar one. The problem must be gone.
