In the event of a customer complaint and if both fault codes are entered, replace the existing
control unit for auxiliary alarm system with a new control unit with software version '0820'
printed on it, see PIWIS information system under TEQ Tequipment Installation and Conversion
Instructions  Installation and Conversion Instructions '906400 Porsche Vehicle Tracking System (PVTS)
control unit' or (for the Cayenne) under  Workshop Manual '906425 PCC' in the Workshop Manual.
Information
Before starting the work required for replacing the PVTS control unit, the replacement procedure must
first be started in the ‘Porsche Car Connect – Online Support’ portal. If PCC/PVTS is activated, you
will then get the installation code required for commissioning and activating the new control unit.
Without the installation code, the PVTS control unit cannot be replaced and subsequent
commissioning of the new control unit is not possible for an activated PCC/PVTS.

Information
The subsequent procedure depends on the respective usage status of PCC/PVTS
•

If PCC/PVTS has already been used and a valid user contract exists, the new PVTS control unit must
be commissioned in order to guarantee continued use. This requires the installation code obtained
previously from the 'Porsche Car Connect – Online Support' portal. More information about this
can be found in the PIWIS information system under TEQ Tequipment Installation and Conversion
Instructions  Installation and Conversion Instructions '906400 Porsche Vehicle Tracking System
(PVTS) control unit' or (for the Cayenne) under  Workshop Manual '906425 PCC' in the Workshop
Manual.

•

If the customer has not yet started using PCC/PVTS or if there is no valid user contract and if the
customer does not intend to use PCC/PVTS in the future, there is no need to commission the control
unit.

•

If the customer has not yet started using PCC/PVTS or if there is currently no valid user license, but
the customer wants to activate or reactivate PCC/PVTS while the control unit is being replaced,
proceed in accordance with the standard process for activating PCC/PVTS for the first time or
reactivating PCC/PVTS. To do this, an account must be created and a new installation code must
be requested via the ‘Porsche Car Connect – Online Support’ portal. The new PCC/PVTS
control unit must then be commissioned. More information about this can be found in the PIWIS
information system under TEQ Tequipment Installation and Conversion Instructions  Installation
and Conversion Instructions '906400 Porsche Vehicle Tracking System (PVTS) control unit' or (for
the Cayenne) under  Workshop Manual '906425 PCC' in the Workshop Manual.
