Read out and erase the fault memory
Workshop Manual '9X00IN Basic instructions
and procedure for control unit programming
using the PIWIS Tester'.
Repeat control unit programming by entering
the programming code again, whereby
extended logging must be started using the key
combination •Ctrl“ + •L“.
Extended logging records diagnostic software
data, particularly vehicle communication data,
which is required for analyzing the issues that
caused programming to be aborted.
If control unit programming is aborted a second
time, stop operational readiness for approx.
15 minutes (switch off ignition) and repeat the
procedure described here again.

procedure for control unit programming using the
PIWIS Tester - section on "Fault finding"'.
Re-program the central computer (PCM) (sequence 4).
