Seat heating
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.
For seat heating, a seat heating module or the higher-quality driver seat module can be installed. A seat module is always installed with seat memory. The junction box electronics (JBE) send a query to determine whether seat module is installed. If the junction box electronics do not receive confirmation, the junction box electronics handle activation of the seat heating. The junction box electronics generate a pulse-modulated signal. This signal activates the seat heating module.
If a seat module is fitted, the seat heating is activated directly by the seat module.
