Peugeot 407 F089 error

Hello friends. When I connect the vehicle to the device, I get a lack of communication error with the F089-Malfunctioning headlights calculator. What should be the reason and where to look? Note: The vehicle has original xenon.

possibly a condition related to the brain. sockets etc. I recommend you to check.

I might think of the sensors that calculate the slope of this vehicle. I want to check them. Where are these sensors?
