Bi-stable relay

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.

The bi-stable relay is used to shut down terminal 30g-f if there is a closed-circuit current fault. The relay is only fitted for certain optional extras (e.g. CIC, TCU, ULF). If a bistable relay is fitted, an intelligent battery sensor is also fitted
