Read and follow the information and instructions
on the PIWIS Tester during the guided programming
sequence.
During the programming sequence, first the ‘highvoltage battery’ control unit and then the ‘air conditioning control’ control unit is re-programmed and
then re-codedautomatically.

Programming sequence:

Do not interrupt programming and coding.
Once the control units have been programmed and
coded, the PIWIS Tester will prompt you to switch the
ignition off and then back on again after a waiting time
of approx. 1 minute.
Any instructions relating to required subsequent
work that may be displayed on the PIWIS Tester
display can be ignored as all required subsequent
work must only be carried out after all control units
to be programmed during this campaign have been
programmed.
The required subsequent work is described at the
end of the control unit programming instructions.

function in the Additional menu on the PIWIS Tester
by entering a programming code.

Programming code:

L9M5Z

Programming sequence:

Read and follow the information and instructions
on the PIWIS Tester during the guided programming
sequence.
During the programming sequence, the control unit
for left rear axle steering is re-programmed first,
then the control unit for right rear axle steering is
re-programmed automatically. Once programming is
complete, both control units are re-codedautomatically.
Do not interrupt programming and coding.
Once the control units have been programmed and
coded, the PIWIS Tester will prompt you to switch the
ignition off and then back on again after a waiting time
of approx. 1 minute.
Any instructions relating to required subsequent

Performing software update for Porsche Communication Management (PCM).
Information
The PCM update is performed using an SD card, which is inserted into the PCM card reader
instead of the SD card for the navigation data.
The SD card for the PCM update (Part No. 918.642.901.00) must be used once for each Porsche
Centre responsible for looking after a vehicle affected by the campaign.
As soon as the PCM update has been performed, the SD card for the PCM update must be removed
from the PCM card reader and the SD card for the navigation data must be re-inserted into the card
reader.
The SD card for the PCM update remains in the Porsche dealership.
To perform the PCM update using the SD card, the operating mode for the multimedia control
unit must first be changed using the PIWIS Tester as described below and must be reset to the
standard setting again when the update is complete.

Perform automatic coding.

Information
If the fault memories of individual control units for the hybrid system (e.g. high-voltage battery control
unit, etc.) cannot be erased, the reason for this may be that on-board diagnosis of the hybrid system
was not completed fully.
Proceed as follows in this case:
•

Switch off ignition.

•

Disconnect the PIWIS Tester diagnostic connector from the diagnostic socket.

•

Lock the vehicle using the driver’s key.

•

Unlock the vehicle again after a waiting time of at least 10 minutes.

•

Plug the PIWIS Tester diagnostic connector into the diagnostic socket again and restore communication with the vehicle.

•

Read out the fault memories of these control units again and erase the fault memories separately.

If control units are found to have faults which cannot be erased and are not caused by control unit
programming, these faults must be found and corrected. This work cannot be invoiced under the
workshop campaign number.
