Reading and printing values
Information
If the instrument cluster is replaced or exchanged, the instrument cluster must be programmed and coded using the PIWIS Tester 9718. This is done to adapt the instrument cluster to the vehicle and equipment.
If possible, before the instrument cluster is removed and replaced, a read-out of the vehicle data should be obtained using the Porsche System Tester.
During coding, it is essential to guarantee the power supply for the Porsche System Tester. It is essential to connect a battery charger with a current rating of at least 40 A to the vehicle battery.
The Porsche System Tester instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.
The procedure described here has been structured in general terms; different text or additions may appear in the Porsche System Tester.
