Pour le cablage c'est exact. Pour accéder à certains calculateurs du Cayenne qui ne communiquent pas en protocole CAN mais en K-Line il faut relier le Pin 7 avec le Pin 3 du cablage OBD2. Chez VAG tout le K-Line passe sur la pin 7 mais sur Porsche non et VCDS travaille en mode VAG. Les modules qui parlent en CAN protocol passent par Pin 6/Pin 14 chez VAG et chez Porsche.
Pin 1 = Terminal 15 power(also known as key on power)
Pin 3 = K-Line 2 (communications wire for all modules except engine)
Pin 4 = Terminal 31 ground (very common for the car missing this ground pin)
Pin 5 = Terminal 31 ground
Pin 6 = CAN High
Pin 7 = K-Line 1 (communications wire for engine but is routed through the drive block system)
Pin 14= Can LOW
Pin 15 = L-Line (communications wire for most of the car modules used to wake-up the module)
Pin 16 = Terminal 30 (battery power)
Pin 1 = Terminal 15 power(also known as key on power)
Pin 3 = K-Line 2 (communications wire for all modules except engine)
Pin 4 = Terminal 31 ground (very common for the car missing this ground pin)
Pin 5 = Terminal 31 ground
Pin 6 = CAN High
Pin 7 = K-Line 1 (communications wire for engine but is routed through the drive block system)
Pin 14= Can LOW
Pin 15 = L-Line (communications wire for most of the car modules used to wake-up the module)
Pin 16 = Terminal 30 (battery power)
