Information
The subsequent procedure depends on the respective usage status of PCC/PVTS
•

If PCC/PVTS has already been used and a valid user contract exists, the new PVTS control unit must
be commissioned in order to guarantee continued use. This requires the installation code obtained
previously from the 'Porsche Car Connect – Online Support' portal. To commission the control
unit, continue with  Technical Information 'WF5900 Commissioning new PVTS control unit'.

•

If the customer has not yet started using PCC/PVTS or if there is no valid user contract and if the
customer does not intend to use PCC/PVTS in the future, there is no need to commission the control
unit and carry out the subsequent function test. In this case, continue with  Technical Information
'WF5900 Reading out and erasing fault memories'.

•

If the customer has not yet started using PCC/PVTS or if there is currently no valid user licence, but
the customer wants to activate or reactivate PCC/PVTS while the control unit is being replaced,
proceed in accordance with the standard process for activating PCC/PVTS for the first time or
reactivating PCC/PVTS. To do this, an account must be created and a new installation code must be
requested via the ‘Porsche Car Connect – Online Support’ portal. The new PCC/PVTS control
unit must then be commissioned. To do this, continue with  Technical Information 'WF5900
Commissioning new PVTS control unit'.

Commissioning the new PVTS control unit
NOTICE
Control unit commissioning will be aborted if the Wi-Fi connection is unstable.
•

An unstable Wi-Fi connection can interrupt communication between PIWIS Tester II and the vehicle
communication module (VCI). This can result in abnormal termination of the control unit commissioning
process.

Carrying out a function test
Procedure:

1

Press •F8“ to start the PCC/PVTS function test
 PCC/PVTS function test.
The following routines are carried out during the
function test:
•
•

"Re-start inhibitor" function test
"Alarm horn and direction indicator" function test

At the start of the "Re-start inhibitor" function test, the
PIWIS Tester will prompt you to switch off the ignition.
2

Switch off the ignition and press •>>“ to confirm the
prompt.

PCC/PVTS function test

The fault memory entry "Re-start inhibitor activated by PVTS" is written and a status message to this
effect appears on the PIWIS Tester display.
3

Check that the re-start inhibitor is active.
Information
After the ignition is switched on, "E-power" driving mode is activated automatically if the state of
charge of the high-voltage battery is high enough (SoC > 35%). Given that purely electric driving is
the preferred driving style in this driving mode, the combustion engine is not started when terminal
50 (engine start) is actuated.
To make sure that the re-start inhibitor is active and the combustion engine cannot actually be
started, the “Sport Hybrid” or “Race Hybrid” driving mode must first be selected using the MAP
switch on the steering wheel.
3.1

Switch on ignition.

3.2

Select “Sport Hybrid” or “Race Hybrid” driving mode. To do this, turn the MAP switch (driving
mode controls) on the steering wheel until the LED corresponding to the letter "S" or "R" in the
MAP switch lights up.
The display "Sport mode" or "Race mode" also appears in the information display on the
instrument cluster.

3.3

Turn the ignition key in the ignition lock to position 2 (terminal 50 – 'Engine start') to make
sure that the re-start inhibitor is active and the combustion engine cannot be started.

4

Once the re-start inhibitor is checked successfully, switch off the ignition again and press •>>“ to
continue.

5

The PIWIS Tester will then prompt you to switch on the ignition.
Switch on the ignition and press •>>“ to confirm the prompt.
