Operating readiness

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.

Operational status (operating readiness) depends on the terminal.

Terminal 30B (basic operation) and terminal 30
The instrument cluster is connected to terminal 30B and terminal 30 via the junction box. The terminal status (Terminal R or Terminal 15) is made available to the instrument panel via the bus system. With Terminal 30 (Terminal R OFF), the instrument panel is in standby mode. Pressing the reset button wakens the instrument panel to display the following: Odometer, time display, ambient temperature, fuel level (can be encoded). The display goes out after 25 seconds.
Terminal R
With terminal R On, the following are evaluated: Turn signal/high beam switch and fuel level sensor. The time and ambient temperature appear in the TFT display. The on-board computer functions can be started using the on-board computer button (display unlimited in time).

Terminal R is reached automatically once the engine has been stopped .
Terminal 15
When Terminal 15 is switched ON, a pre-drive check is carried out on the permanent indicator and warning lights.
Terminal 50 (starter motor)
During the engine start, the vehicle voltage can fall to such a degree that the internal voltage supply (6 Volts) can no longer be maintained. In this case, no analogue signals can be evaluated. No storage processes are run (in the EEPROM) either.
