Work Procedure: 1

The basic procedure for control unit programming is described in the Workshop Manual ⇒ Workshop
Manual 'Basic Instructions and Procedure for Control Unit Programming Using the PIWIS Tester'.

2

After the backup documentation process, the integration test is started automatically. The result can be
ignored for the time being.

3

Create Vehicle Analysis Log (VAL) using the PIWIS Tester. Mark the vehicle analysis log you have just
created with the attribute “Pre-VAL” and after carrying out the campaign, return it using the PIWIS
Tester.

4

Only valid for vehicles with Scope 1: Change vehicle order.
4.1

In the control unit selection (‘Overview’ menu) press •F7“ to call up the Additional menu.

4.2

Select ‘Vehicle data care with PIWIS ONLINE’ and press •F12“ (‘Next’) to confirm.
The guided Tester procedure starts and the vehicle data is compared between the vehicle and
PIWIS ONLINE.

4.3
5

Save the changes by pressing •F8“.

Update software of various control units (Sequence 1). (Valid for all scopes)
For specific information on control unit programming during this campaign, see the table below.

Information
Before starting programming, the battery charger must necessarily be:
•

Switched off and on once; the battery charger display must be off before starting it again, because the
battery charger automatically switches to trickle charging after 5 hours (default setting in the charger).

•

Operate in charging mode.

•

The vehicle must be on a level surface.

•

Air suspension must be at normal level.

•

Switching off air-conditioning system.

•

Vehicles with a PVTS contract must have Service mode activated.

•

An active Internet connection with the PIWIS Tester must be maintained.

•

To log in using the PIWIS Tester, the technician is required.

•

Place the original remote control in the emergency start tray (note the position)!

•

The PIWIS Tester must not be charged using the cigarette lighter!

Information
Please inform the customer that the set values are lost after updating the instrument cluster.

Required PIWIS Tester software release:

43.100.020 (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:

G3C1P

Programming sequence:

Read and follow the information and instructions on
the PIWIS Tester during the guided programming
sequence.
Do not interrupt the programming and coding
process.
After programming has been carried out, the result
of the programming must be checked and, in the
event of deviations from individual control units, the
corresponding control unit must be re-programmed
or re-coded.
A backup documentation process for the
re-programmed software releases starts as soon as
programming and coding is complete.

Programming time (up to):

•
•

215 minutes
The duration of the programming the control
units depends on the build status and can differ
from the specified time.

Control units programmed in this campaign:

•

When programming is complete, backup documentation including the integration test is done again.
The result must first be ignored because this sometimes displays control units that are displayed as
faulty despite programming.
To check this, the integration test must be started again on the start page by pressing the •F3“
button. This process must be repeated up to three times.
If this results in a discrepancy here, the relevant control unit must be re-programmed. The central
computer (PCM) control unit is not to be programmed initially because this is programmed in sequence
2.

7

Only valid for vehicles with Scope 1 or 2: Re-program the central computer (PCM) (sequence 2).
For specific information on control unit programming during this campaign, see the table below.
Overview of the software to be used for the central computer (PCM): ⇒ Technical Information '9X00IN
Overview of PCM update'
7.1

Preparing USB stick with the required software (depending on country version)

7.2

The battery charger must be switched off and on completely once before sequence 2 due to the
automatic switchover (trickle charging).

7.3

Select the Guest account from the central display (PCM) and activate Privacy mode (available in
some countries).
Information
If Privacy mode is not active, programming may be aborted, resulting in a defect in the central
computer (PCM). Central computers that are replaced as part of the workshop campaign are
checked by Porsche AG; if private mode was not set in the central computer before starting
programming, the costs will be re-debited.
Required PIWIS Tester software release:

43.100.020 (or higher)

Type of control unit programming:

In the control unit selection ("Overview"
menu), select the PCM central computer
control unit and select the "Service / Repairs"
menu.
Select the "Install software update" function
and press •F12“ ("Next") to perform the
software update.
