Coding interior monitoring sensor

INFORMATION:
- If the interior monitoring sensor is replaced, the sensor must be coded in the control unit using the PIWIS Tester 9718. This adapts the interior monitoring sensor according to the vehicle variant and equipment.
- During coding, it is essential to guarantee the power supply for the Porsche System Tester. A battery charger with a current rating of at least 40 A must be connected 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.

1. Connect the Porsche System Tester to the vehicle and start the System Tester. Switch on the ignition and press >> to continue.
