A new feature of the diagnostic session is the option of switching directly to PQIS,
which is activated using the F1 button. This allows users to display the workshop

6.2 Immobiliser and component protection
The ‚Immobiliser‛ button can be used to call up teaching functions for engine
immobiliser 4 (Cayenne 9PA 2008-2010 Diesel). This mainly concerns the components
“
Electric steering column lock
“
Kessy control unit
“
DME control unit

Vehicle key
Engine immobiliser 4 only concerns the Porsche Cayenne Diesel, model year 2008-2010.
The individual components are ‚married‛ together during the teaching process so that they
can only be replaced online with the required registration for security reasons.
The teaching process for newer engine immobilisers (e.g. engine immobiliser 5) is carried
out directly in the diagnostic session for the control unit and is taught online.
Engine immobiliser 5 is taught from
within the diagnostic application!
