can be up to 40 minutes.
Read and follow the instructions displayed on the PIWIS Tester during the update. The PCM is
restarted several times. The PCM screen remains dark for up to 3 minutes.
Information
Once the PCM software update has been performed, the last step 'Check PCM status' is
next. An error message may be displayed here. This error message can be ignored if there
is no active fault memory entry in the PCM fault memory after carrying out this campaign.
If there is an active fault memory entry, it must be found and corrected.

Concluding work
Information
The currently valid version of the Onboard Owner’s Manual is available online since April 17, 2019.
The Onboard Owner’s Manual is downloaded from the backend for each specific vehicle. The Tester must
be connected online in order to do this.
A blank SD card is required for installing the onboard operating instructions (approx. 100 MB). If there is
already data stored on the SD card, this will be deleted during the procedure.
Work Procedure: 1

Re-code all control units.
1.1

Select all control units in the control unit selection screen ('Overview' menu) and press
•F12“ ('Next') to confirm your selection.

Automatic coding

Information
It may not always be possible to code the control unit for Tire Pressure Monitoring (TPM).
This will also be indicated as 'not carried successfully' by an X in the 'Status' box in the
general overview following control unit coding.
If this is the case, the tire size must be set in the Vehicle menu.
To do this, set the size of the fitted tires under 'CAR'  'CONTROL'  'Vehicle'  'Tire
pressure monitoring'  'Tire selection' in the Porsche Communication Management
(PCM) menu.
Then, perform automatic coding again in the 'Codings/adaptations' menu in the 'Tire
Pressure Monitoring (TPM)' control unit.
