GF88.79-P-2010TX Automatic Dimming Outside And Inside Rearview Mirror, Function

Component Identification:

Function requirements
^ Circuit 15R On or circuit 15 ON
^ No overvoltage or undervoltage

Function
The mirror glass of the inside rearview mirror and left outside mirror can be dimmed electro-chromatically.This is realized by a layer of electrolyte gel in the corresponding mirror, which regulates the light permeability depending on the voltage applied in increments
The inside rearview mirror senses the ambient light via the front mirror dimming sensor and the light hitting the surface of the mirror glass via the rear mirror dimming sensor.

The inside rearview mirror evaluates these input variables and supplies dimming information to the overhead control panel control unit which transmits the message for mirror dimming tot he CAN-B bus.
The left front door control unit relays the dimming information and supplies the corresponding actuation voltage to the mirror dimming of the left outside mirror.The dimming information for the inside rearview mirror is taken over by the overhead control panel control unit, which supplies the voltage to the mirror dimming of the inside rearview mirror.

If, during mirror dimming, the inside illumination is switched on or the reverse gear is engaged, dimming is stopped.
