Kia Sportage: Electro Chromic Inside Rear View Mirror / Description and operation
Kia Sportage QL (2015-2024) Service Manual / Body Electrical System / Electro Chromic Inside Rear View Mirror / Description and operation
| Description |
The ECM (Electro Chromatic inside rear view Mirror) is one that automatically
dims to protect the driver’s eyes when it senses light reflecting from the car
behind. The sensor in the mirror detects the brightness and if the headlight
from the car behind is reflected on the mirror, the chemical layer inside the
mirror reacts to glare and adjusts the reflectivity from 10 to 70%. When switching
to the reverse gear, the mirror becomes bright regardless of the surrounding.
The ECM receives voltage, ground and reverse gear signals, and uses two sensors
to measure the intensity of glaring.
| 1. |
The forward facing sensor determines whether the surrounding space is
dark enough to activate the function.
|
| 2. |
The rearward facing sensor detects the glare on the mirror. If the glare
is detected, the sensor transmits the signal for the mirror to dim
|
| 3. |
The ECM is darkened to the level as determined by the rearward looking
sensor. When the glaring is no longer detected, the mirror stops functioning.

Forward looking sensor)

function can be controlled by the Dimming ON/OFF Button :
