Checklist:
Due to the high number of programming steps incorrectly carried out as part of the last software update, a

checklist was created to improve the overview of the work to be carried out. This can be used as a tool at the

start and for support during the update.

The checklist must be completed, signed and attached to the PQIS quality line in the PCSS.

For the checklist, see ⇒ Technical Information 'Checklist'

Please see note attached on PPN page for this campaign.

Vehicle update – general information

The entire vehicle network will be checked for a necessary update or computed to ensure fault-free functioning of the vehicle. For this purpose, the following preparations are to be made:

•
Latest release on available on Porsche Tester 4 and PiUS
•
Vehicle is fully assembled
•
To prevent potential faults due to insufficient data transfer, carry out the software update using

a cable (between VCI and Porsche Tester). Only if sufficient WLAN availability is ensured in the

workshop can a wireless update be performed
•
The user must be logged into the Porsche Tester 4 in the PPN
•
The vehicle must be supported with an external charger
•
Seat heating and seat ventilation are not active
•
Place the original hand-held transmitter in the emergency start tray (see Workshop Manual)
For this update procedure, the respective vehicle no longer needs to be in transport mode

Procedure for new vehicles with active transport protection:

Perform “Vehicle handover” routine according to the Porsche Tester instructions, to deactivate transport

protection.

Always make sure: to answer the question of “Is this a new vehicle?” asked by the Tester with No!

As a result, no complete vehicle commissioning is carried out and only transport protection can be deactivated.

Work Procedure: 1
Observe preconditions for control unit programming.
⇒ Technical Information '9X10IN Basic instructions and procedure for control unit programming using

the PIWIS Tester'
Information

An active internet connection with the Porsche Tester must be ensured.

The technician must log in to PPN with the Porsche Tester.

The Porsche Tester must not be charged using the cigarette lighter.
Information

Before starting the diagnosis, it is essential for an ignition change to be performed on the vehicle.

Subsequently, after starting the diagnosis, the VCI will be automatically initialized and the control unit

data is loaded.

For additional information on the programming procedure and when the process is aborted, see ⇒

Prepare an update of the various control units on software network VR28.13.

2.1
Start new logging via •P2“.
2.2
As soon as the control unit overview is displayed, open the additional menu •F7“.

Create a Vehicle Analysis Log (VAL). Mark the created VAL with the attribute “Pre-VAL” and, after

carrying out the campaign, return it using the Porsche Tester.

An overview of all campaigns to be carried out for the respective vehicle is then displayed automatically.
2.3
Exit the overview of the actions to be carried out for the respective vehicle by pressing •F12“.
2.4
Cancel the automatic integration test on the Porsche Tester by pressing•F11“.
Information

Due to overload of the onboard tester, an interruption may occur intermittently in the step “Onboard tester

downloads update”.

In this case, the Porsche Tester will automatically restart the entire update process.

No intervention by the user is required!The Tester should automatically begin the update again. If it does

not automatically begin again, manually execute the function "Programming and coding control units

(campaign)" again

3
Update the software of various control units on software network VR28.13.

In the displayed additional menu, select and confirm the “Control unit programming and coding

(campaign)” menu item.

The required updates to the incremented software network VR28.13 are then displayed.

Start the software update with •F8“ and program as per the menu.

After the update has been completed, a corresponding confirmation is displayed on the Porsche Tester.

All affected control units should now be successfully programmed or checked in the results view

showing the control units and their status.

Information

If a deviation in the integration test is still indicated despite the programming carried out, this must be

repeated. If the deviation persists, contact Technical Support.
Information

The download speed of the update package depends on the performance of the local network and can

vary accordingly.

Information

During the update process, all displays in the vehicle (instrument cluster, central display and passenger

display) are occasionally switched off. Nevertheless, the programming is ongoing, the ignition must not

be switched on/off, as this can result in the destruction of the control units.

During the update, a buzzing of the acoustic simulator will sound several times. This noise is normal

and indicates an ongoing update of the HCP1 drive and chassis main control unit (J1312).

If Wi-Fi coverage is insufficient, the connection

between the Porsche Tester and VCI can be interrupted

(battery charge indicator at the top right inactive on the

Tester display). The vehicle will, nevertheless, continue

programming independently. In the meantime, no

entry may be made on the Porsche Tester, and the

programming must not be restarted. In this case, the

update progress can still be checked in the vehicle in

the front display and control panel (R238) by going to

the “Messages” (RPC+) tile.
