Bluetooth headset: A separate headset can be
connected for in-car video. Audio sources can thus
be disconnected from the driver and passenger. This
means that the music, for example, can be played
independently for the driver and video audio can be
played through the headset for the passenger

Overview of PCM update
Information
The central computer (PCM) software update is performed using a USB storage medium. The software
release that is specific to each region must be downloaded using the PiUS (Porsche integrated Update
Service) software tool and must be installed on a blank USB storage medium.
Pay particular attention to the following:
•

For this PCM software update, a USB storage medium USB Type A+C 32 GB must be used.

•

To use the software tool, one blank or re-writable USB storage medium is required for each individual
software.

•

The software available in PiUS must only be used in accordance with the instructions provided in a
Technical Information published for this purpose.

The software mentioned here must only be used on the vehicles assigned to the campaign. Damage to the
central computer cannot be ruled out if the software is used on other vehicles.
You will find further information on installation and use for the PiUS software tool in the PPN portal under

Additional instructions if programming is aborted
Information
If individual programming steps or reworking could not be carried out correctly, see Workshop Manual for
the basic procedure for control unit programming using the PIWIS Tester ⇒ Workshop Manual '9X00IN
Basic instructions and procedure for control unit programming using the PIWIS Tester – section on
“Troubleshooting”'
In the event of a fault, logging must always be created during programming using •Ctrl“ and •L“ using the
PIWIS Tester.
As a general rule, if programming is aborted during programming, programming must be continued. The
entire sequence can be started again at any time using the campaign code. The control unit that has already
been programmed is skipped, or programming is started via the integration test. Starting to use the integration test is faster.
You will also find further information and instructions specifically for the VR8 update in the table below:
