Programming power electronics - Scope 5
Information
When the front and rear power electronics is programmed, the DME control unit is also re-programmed
automatically. It takes approx. 10 minutes in total to program these control units.
Before starting programming and after the control units have been programmed successfully, the
procedure for sending backup documentation of the software versions installed on the control units
to the PAG systems will be started automatically.
Work Procedure: 1
Re-program power electronics and engine electronics (DME) control unit.
General preliminary work and the basic procedure for programming a control unit is described in the
Workshop Manual Workshop Manual '9X00IN Basic instructions and procedure for control unit
programming using the PIWIS Tester'.
For specific information on control unit programming during this campaign, see table
below.
Required PIWIS Tester software version:
40.550.040 (or higher)
Type of control unit programming:
Control unit programming using the 'Automatic
programming' function for the DME control unit:
'DME' control unit – 'Coding/programming' menu
– 'Automatic programming' function.
Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
First the DME control unit and then the front
power electronics and rear power electronics
are re-programmed during the programming
sequence.
Programming sequence:
The control units are then re-codedautomatically.
Do not interrupt programming and coding.
Once the control units have been programmed and
coded, you will be prompted to end and then restore
operational readiness after a certain waiting time.
Backup documentation of the new software versions
is then performed.
The programming sequence takes

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 analysing the issues that
caused programming to be aborted.
If control unit programming is aborted a
second time, end operational readiness for
approx. 15 minutes (switch off ignition) and
repeat the procedure described here again.
