Kia Picanto: Body Electrical System / Electro Chromic Inside Rear View Mirror
Components and components location
Description and operation
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. (1. LED indicator, 2. ON/OFF Switch, 3. Rearward looking sensor, 4. Forward looking sensor)

Automatic-dimming Function |
To
protect your vision during nighttime driving, your mirror will
automatically dim upon detecting glare from the vehicles traveling
behind you. The auto-dimming function can be controlled by the Dimming
ON/OFF Button :
1. | Pressing
and holding the Feature Control button for more than 3 but less than 6
seconds turns the auto-dimming function OFF which is indicated by the
green Status Indicator LED turning off. |
2. | Pressing
and holding the Feature Control button again for more than 3 but less
than 6 seconds turns the auto-dimming function ON which is indicated by
the green Status Indicator LED turning on. The mirror defaults to the "ON" position each time the vehicle is started. |

Repair procedures
Check it by the procedure below to see if the function of the ECM is normal.
1. | Turn the ignition key to the "ON" position. |
2. | Cover the forward facing sensor. |
3. | Head a light to the rearward-facing sensor. |
4. | The ECM shall dim as soon as the rearward-facing sensor detects a certain level of brightness. If this test is performed in daytime, the ECM may be darkened as soon as the forward facing sensor is covered. |
|
5. | In the reverse gear, the ECM shall not dim. When directing light to both the forward-facing and rearward-facing sensors, the ECM shall not dim. |
1. | Remove the mirror wiring cover (A) and disconnecting the mirror connector (B).
|
2. | Remove the mirror (A) by pulling up the mirror in the arrow direction below. Make sure not to damage the mounting bracket when removing the mirror. |
|
1. | When installing the mirror, be careful not to damage the mounting bracket. |
