Servotronic

Functional description, see BMW Technology:
TIS -> Document -> SI Technology -> 32 01 03001 (Servotronic valve)

Note on function
The following control modules are involved in the Servotronic function:
- Safety and Gateway Module (SGM)
- Activation of Servotronic valve
- Active steering control module (AL), only with active steering optional extra
- Specified current for the Servotronic valve

The characteristic curve for the speed-dependent activation of the Servotronic valve is stored in the Safety and Gateway Module. With the active steering option, the specified current for the Servotronic valve comes from the active steering control module. The characteristic curve in the Safety and Gateway Module is then switched off.
