of the control unit. If the WSS circuit is broken,
the input of the amplifier recognise a potential
shift caused by the injected current and a fault
is detected.
Effects:
• Control of the corresponding wheel is no
longer possible.
• If a sensor fault occurs on a front wheel,
pressure is increased; on a rear wheel
pressure is decreased (until switch off).
