PSD - Diagnosis with
system tester 9288
General information
The PSD/ABS control unit is suitable for self-
diagnosis. This means that the control unit
can detect, store and output certain faults of
the PSD and the ABS.
Diagnosis is performed with system tester
9288 in combination with the adapter lead
9288/l and the corresponding module (depen-
ding on the language in question).
The diagnosis socket is located next to the
passenger's seat underneath the booster co-
ver. Positive potential is permanently connec-
ted to the PSD/ABS control unit in order to
prevent detected and stored faults from being
deleted when the ignition is is switched off.
PSD diagnosis is not possible with the engine
running.
