Note

If a new DME control module is to be installed in a vehicle, the DME code specified in IPAS and the
immobiliser code must be entered in the DME control module.
The codes are available from IPAS or via the importer.
Follow the instructions on the Tester.
Later versions of the software may display slightly different text or require a slightly different procedure. The
instructions you receive from the tester itself take precedence over this description.

Note

During programming, the electric radiator fans may start.

Note

Depending on the software version of the PIWIS Tester, a new DME control module can be interrogated for
the "old DME programming code". In this case, enter the code from IPAS which is also used for the "new
DME programming code".

In some countries (currently USA, Canada) the Ready status must be obtained following a test drive or by
using the Porsche System Tester after the DME control module has been programmed. If in doubt about this,
contact the relevant importer.

1. Connect the PIWIS Tester 9718 to the vehicle and start the System Tester. Switch on ignition. Press >>

to continue.

2. Select vehicle type. Press >> to continue.

If a DME control module from a different vehicle with ME 7.8 is being used, proceed as follows. As a check,
the immobiliser code of the vehicle in which the control module is being installed (NEW) and of the vehicle
from which the control module has been removed (OLD) is required.
In some countries (currently USA, Canada) the Ready status must be obtained following a test drive or by
using the Porsche System Tester after the DME control module has been programmed. If in doubt about this,
contact the relevant importer.
