X Series E83 X3 2.0d (M47T2) OFFRD
Undervoltage detection and overvoltage detection
The Servotronic valve is no longer supplied with power under the following conditions:
•
Supply voltage less than 9 volts
•
Supply voltage higher than 17 volts
Voltage dips during ignition faults are detected.
Switch-on conditions
Switch-on conditions for the Servotronic are:
-
Terminal 15 ON
-
The engine must be running
The Servotronic only activates the Servotronic valve when the engine is running.
When the engine has started and there a road-speed signal is not supplied the Servotronic sets the maximum
steering force support.
If a plausible road-speed signal is detected the Servotronic valve is activated by the characteristic curve.
If there is still not a (or not a plausible) road-speed signal 5 seconds after the engine has started the minimum
steering force support is set.
