Additional instructions if programming is aborted
Information
If individual programming or rework steps could not be carried out correctly, see Workshop Manual for the
basic procedure for control unit programming using the PIWIS Tester ⇒ Workshop Manual '9X00IN Basic
instructions and procedure for control unit programming using the PIWIS Tester - section on “Fault finding”'. :
In the event of a fault, logging must always be created during programming using •Ctrl“ and •L“ using the
PIWIS Tester.
Porsche AG programmed approx. 100 vehicles before the campaign was published as part of an internal pilot
project; not one single control unit had to be replaced in the vehicles.
As a general rule, if aborted during programming, programming must be continued. The entire sequence can
be started again at any time using the campaign code. The control unit that has already been programmed is
skipped or programming is started via the integration test.
You will also find further information and instructions specifically for the VR19.0.1 update in the table below:
