Job
Electronic control unit -1- via photosensors (2/3) registers the light falling on the mirror in front and behind. If the beam of light from behind is stronger than from the front, a voltage is applied to the conductive coating -8-. The coating is between the panes (4/6) mirrors.
The applied voltage changes the color of the electrolytic layer -5-. The higher the voltage, the more the mirror darkens. As a result, the reflection of the incident light stream is reduced. 7 - silver-reflecting layer.
When reverse gear is engaged, the dimming effect is disabled. This makes it possible to exit the dark garage with the help of the interior mirror.
Examination

2. Cover or tape the photo sensor on the front of the mirror.
3. Light up the photo sensor on the back of the mirror with a flashlight. After a short time, the mirror should darken. The photo sensor is located at the top center behind the mirror.
