Electronic transmission control (EGS)
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 electronic transmission control (EGS) transmits information on the engagement status of reverse gear. This information is processed in the footwell module (FRM). The reversing lights are activated based on the received information.
On vehicles with manual gearboxes, the signal is supplied by the reversing light switch.
The automatic transmission is controlled by the mechatronics module. The mechatronics module is a combination hydraulic unit and electronics module. The hydraulic unit engages the gearbox.
The electronics module contains the electronic transmission control (EGS), the sensors and the electrical connections to the inside of the gearbox.
