Servotronic

Functional description, see BMW Technology:

TIS -> Document -> SI Technology -> 32 01 03001 (Servotronic valve)

Note on function

The following control units are involved in the Servotronic function:

• Safety and Gateway Module (SGM)
  
  • Activation of Servotronic valve
    
• Active steering control unit (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 optional extra, the specified current for the Servotronic valve comes from the active steering control unit. The characteristic curve in the Safety and Gateway Module is then switched off.
