Notes on ABS troubleshooting
for vehicles with PSD
General
PSD = Electronically
controlled
Porsche limited-slip differential.
One control unit controls both the PSD and ABS. The PSD is accommodated
on an additional
prin-
ted-circuit board in the ABS control unit.
Not only PSD system faults are stored in the ABS / PSD control unit, but also some ABS system
faults.
Fault displays via the instrument cluster
On vehicles with PSD, an ABS fault is indicated not only by the ABS warning lamp, but also by a
plain-text display in the instrument cluster (ABS off).
ABS faults automatically
lead to deactivation
of the PSD.
In this case, the display in the instrument cluster changes between:
ABS
and
Off
