Operation and Display Concept
Porsche Dynamic Chassis Control can be operated using the same
chassis control switches Normal, Comfort and Sport that are used for
PASM. PASM and PDCC are configured together, depending on which of
the three chassis control programmes is selected.
In the Comfort setting, PDCC intervention occurs at reduced control
speed so as not to change the character of the high comfort program.
Active system intervention in the Sport program, on the other hand,
occurs at maximum speed in order to optimize performance.
A - Sports chassis
B - Comfort chassis
C - Normal chassis
Enhanced off-road performance is also available automatically as soon
as Low Range is activated.
Diagnostics
In addition to on-board diagnosis by the control units and checks on
sensors and valves, the pressure that exists in the system is continu-
ously monitored. Depending on the engine speed, the nominal pressure
values that are worked out are compared with the current actual
pressure values recorded by the four pressure sensors. If a fault is
detected, PDCC switches to Fail-safe mode.
