Turn signal/high beam switch
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The turn indicator and the high-beam headlight are operated using the turn signal/high beam switch on the left steering column switch of the steering column switch cluster. The signal from the turn signal/high beam switch is transmitted both via FlexRay protocol and through a separate line to ensure functional redundancy. The central gateway module (ZGM) transmits the signal to the CAN bus. This is how the footwell module (FRM) receives the signals from the turn signal/high beam switch. The turn indicator lights continue to operate if the information fails to reach the footwell module (FRM) through the bus system. This redundant data-transmission is also employed for the one-touch flashing and headlight flasher functions.
