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. If the guided airbag procedure is aborted, the airbag must be locked again
manually after completion of sequence 1. For instructions, see: Workshop Manual '695355
Replacing airbag control unit'
•
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'.

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.
