Porsche
service campaign instructions for Workshop campaign WMA5 - Updating Software for Various Control Units.
•
Privacy settings
•
Frequency setting of the garage door opener (Homelink)
Information
After carrying out the campaign, please inform customers that Infotainment updates are available via the
central computer (PCM) and provide them with any help and support they need during installation Infotainment update in central display.
These updates are only available if the customer
has logged in on the vehicle using his/her main user
credentials (Porsche ID). Several updates are available
depending on equipment and these must be installed
one after the other in steps. It can take several minutes
to install these. New functions can only be used when
all updates have been completed and the vehicle has
established bus idle for at least 15 minutes.
Information
Special features of sequence 1:
Infotainment update in central display
•
Distance measuring sensor control unit (ACC): Programming is performed in two stages
because of the high data volume. First, the bootloader ACC is programmed and an error message
is displayed. This error message in step 5 can be ignored and you can continue with the campaign.
Follow the instructions on the PIWIS Tester.
•
Airbag control unit: Manual intermediate steps are required after programming the central control
unit for assistance systems (zFAS). For safety reasons, the airbag is unlocked during a guided
procedure prior to coding and is then locked again when coding is complete. Follow the instructions
on the PIWIS Tester.
•
Rear-end electronics control unit (BCM 2): If the driver's key is not detected in the vehicle,
programming of the rear-end electronic cannot be started or will be interrupted. You must therefore
position the driver's key with the back facing forward upright between the holding struts in the rear
cupholder (emergency start tray) to guarantee a permanent radio link between the vehicle and
remote control.

Start control unit programming sequence 1.
The basic procedure for control unit programming is described in the Workshop Manual
Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the
PIWIS Tester'.
Sequence 1:
For specific information on control unit programming in this sequence, see the table
below:
Required PIWIS Tester software version:
40.000.045 (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.

Following control unit programming, the software
version can be read out of the relevant control unit in
the 'Extended identifications' menu using the PIWIS
Tester.
Procedure in the event of abnormal
termination of control unit programming:
•
•
•
•
•
Procedure in the event of error messages
appearing during the programming
sequence:
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 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.
Workshop Manual '9X00IN Basic instructions and
procedure for control unit programming using the
PIWIS Tester - section on "Fault finding"'.
Information
Special features of sequence 2:
•
Battery sensor (12-volt vehicle electrical system battery): An actual voltage of at least 14
volts is required for programming the 12-volt battery sensor. Switching the ignition off and on again
after one minute is therefore integrated in the programming sequence. As a result, the voltage of the
12-volt vehicle electrical system battery increases briefly and the programming sequence can be
started. Follow the instructions on the PIWIS Tester.
