 If the headlights cannot be switched off (e.g. daytime driving lights), make sure that the headlights are not covered (by protective covers)
 Switch off the wiper/washer system. The wipers may be actuated during vehicle programming/encoding and encoding initialisation. Make sure that the wiper can move freely
 Make a note of all stored radio and TV frequencies and destinations
 Connect up a battery charger that is currently approved by the BMW Group in the engine compartment. Only chargers recommended by BMW are to be used in order to prevent damage to vehicle electronic components. All up-to-date chargers can be found in the Aftersales Assistance Portal under: Building and Equipment Consultation > Workshop Equipment.
 F-series and E-series with "Efficient Dynamics" (optional equipment 1CC): With the "DBL1200" and "DBL1600" or "MultiCharger 1500" chargers, the battery charge mode is used for programming. This battery charge mode is set at the factory on delivery of the devices and must not be changed. The set maximum voltage of 14.8 volts in battery charge mode is not to be exceeded.
 E-Series without "Efficient Dynamic": All chargers recommended by BMW, such as "DBL 430", "DBL800", "MultiCharger 750" or "MultiCharger 900" can be used. The "FSV mode with connected battery" is still used for these chargers. The maximum voltage of 14.2 volts is not to be exceeded. Possibly a charge parameter setting is necessary.
 Do not connect or disconnect the battery charger during vehicle programming/encoding. If the vehicle voltage is too low, it can cause vehicle programming/encoding to be aborted. Make sure that the vehicle voltage does not drop below 13.0 volts while vehicle programming/encoding is in progress.
 Check the cable routing. Cables routed through open windows could be damaged when the windows are automatically initialised. Do not route cables through open windows
 Switch on the ignition (terminal 15), before the ICOM vehicle interface is connected to the vehicle
 On vehicles with Comfort Access, the ID transmitter must be inserted in the ignition lock. If the ID transmitter is not inserted in the ignition lock, this could cause encoding to be aborted
 If there is no ignition lock on the model concerned, the ID transmitter must be inside the vehicle
