Coding the sensor

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

Vehicles with junction box electronics (JBE):

At each new start, the junction box electronics (JBE) check whether the coding data stored in the rain-light and precipitation sensor match the target coding data stored in the junction box electronics (JBE). In the event of deviations, the junction box electronics (JBE) run automatic encoding of the rain-light-solar-condensation sensor in accordance with the target coding data.

Vehicles with Front Electronic Module (FEM) or Body Domain Controller (BDC):

At each new start, the front electronic module (FEM) or body domain controller (BDC) sends a configuration telegram for vehicle-specific configuration of the rain-light-solar-condensation sensor.

The automatic driving lights control provides an encoding possibility to change the sensitivity settings (Japanese version: changed sensitivity settings).
