Read out and delete the fault memory.
Information
Due to the vehicle diagnosis and programming status (new vehicles), fault memory entries that do not
indicate an actual fault in the vehicle may be stored.
These fault memory entries, for the most part, can be deleted after vehicle handover has been
completed and a test drive.
The following fault memory entry is always stored as part of a vehicle diagnosis with the Porsche Tester
and does not represent an actual fault.

additional menu and select the creation of the protocol.
Mark the created vehicle analysis log with the attribute “Post-VAL” and return it using the Porsche Tester
after the campaign has been carried out.
11 Carry out a plausibility check of the battery capacity according to the instructions of the Porsche Tester.
11.1
Open high-voltage battery control unit (J1120).
11.2
Open “Maintenance/Repairs” menu
11.3
Select the menu item “Plausibility check of battery capacity” and carry it out.
•
If no abnormalities were detected during the plausibility check of the battery capacity, end
the procedure with •F12“ and continue with work step 13. Scope 1 of this campaign will
need to be invoiced.
•
If the plausibility check of the battery capacity results in a deviation, repeat the test as
described and follow the guided Tester procedure. If it was not possible to re-initialize the
calculation of the battery capacity, it is not necessary to create the Vehicle Analysis Log at
this point; ignore the corresponding instructions of the Tester.
Information
If the plausibility check of the battery capacity has resulted in a deviation and the Tester
procedure has been carried out to reset the battery capacity learning values, scope 2 of this
campaign will then need to be invoiced.
In addition, the customer must be informed about the temporary deviation of the range display
based on the FAQs for this campaign when returning the vehicle.
12 Read out the fault memory again and erase it.

15 Switch off and disconnect the battery charger.
Information
During the test drive, the GPS is reconnected, and the tire settings must be checked and, if necessary,
adjusted again.
After the test drive, individual customer settings must be restored.
The activities performed during the test drive and after the test drive do not have to be carried out by
the technician.
Note: The test drive does not necessarily have to be carried out by a technician but could be done by
another service employee at the Porsche Center, for example.
16 Carry out the test drive, then restore the customer settings.
17 After the update has been successfully completed, all 4 doors must be checked to ensure they are
locking correctly.
To do this, proceed as follows:
Lock the vehicle with the handheld transmitter. Remove the handheld transmitter from the vicinity of
the vehicle (> 30 feet). Check that all 4 doors are locked correctly by pulling on the door handle.
