Summary
Porsche
service campaign information for Workshop campaign WMA6 - Updating Software for Various Control Units.
Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the
PIWIS Tester'.
Information
Special features of sequence 1:
In this sequence, manual intermediate steps are required after the central control unit for assistance
systems (zFAS) is programmed. For safety reasons, the airbag is triggered during a guided
procedure prior to coding and is then locked again when coding is complete. Follow the instructions
on the PIWIS Tester.
Sequence 1:
For specific information on control unit programming in this sequence, see the table
below:
Required PIWIS Tester software
version:
40.000.018 (or higher)
Type of control unit programming:
Control unit programming using the 'Campaign' function
in the Additional menu on the PIWIS Tester by entering a
programming code.
Programming code:
K4M1S
Programming sequence:
Read and follow the information and instructions on the
PIWIS Tester during the guided programming sequence.
Do not interrupt programming and coding.
A backup documentation process for the re-programmed
software versions starts as soon as programming and
coding is complete.
Programming time (approx.):

End and restore operational readiness (switch ignition
off and then on again).
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 analysing 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.
