General Preliminary Work
- If it is easy to reach, disconnect the electric plug connection for the fan blower -1-
(-arrow-
) to prevent the blower from coming on during control unit programming.
Having the fan on and the associated increased current draw can cause a drop in voltage, which can result in abnormal termination of control unit programming.
- Connect a battery charger with a current rating of at least 40 A (e.g. battery charger HFL 65 WE 1353 ) to the jump-start terminals in the engine compartment and switch it on.
- Switch on the ignition using the original driver's key . On vehicles with "Porsche Entry & Drive", do this by replacing the control panel in the ignition lock with the original driver's key if necessary.
- PIWIS Tester II 9818 must be connected to the vehicle communication module (VCI) via the USB cable . Then, connect the communication module to the vehicle and switch on the PIWIS Tester.
