Coding the gateway control unit
If possible, before the gateway control module is removed and replaced, a read-out of the vehicle data should be obtained from 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.
