The wake-up signal
to wake the adaptive air suspension control
unit from sleep mode is transmitted by the
comfort system central control unit J393.
It uses a pulse-width-modulated signal.
The duration of the signal pulse varies
depending on whether the doors and/or boot
lid are opened or closed.
J393 transmits a signal even if terminal 15 is
detected but the doors and/or boot lid are
not opened or closed.
