Voltage Supply The Voltage supply concept of the FI 0 is based on that of the F01. The components and the structure used are largely the same. 2.1. Components Due to the steady increase of electrical functions for comfort, communication and safety in BMW vehicles, the voltage supply is becoming ever more important. In the FI 0, two separate power distribution boxes with fuse blocks are installed. The front power distribution box with fuse block is near the glove box and the rear power distribution box with fuse block is on the right-hand side of the luggage compartment. The front power distribution box with fuse block forms the junction box together with the junction box electronics (JBE). In the graphic below, you can see the layout of the most important components of the voltage supply system in the F10. In the FI 0, three main power lines (bolted to on the underbody of the vehicle) are run from the power distribution box on the battery to the engine compartment: • One of the main power lines runs via the positive battery terminal to the starter motor and to the alternator. • The second line supplies the electronics box in the engine compartment with voltage for the engine electronics. This line is protected by a high-current fuse in the distribution box at the battery. • The third line leads to the engine compartment power distribution box. This distribution box supplies the electric fan with power. This line is protected by the high-current fuse in the distribution box at the battery. In addition, a battery cable is routed through the vehicle interior to the front power distribution box with fuse block. This line is also protected by a high-current circuit breaker. Depending on the model, different line cross sections are used. The transfer points for the main power cables are located under the luggage compartment floor. The main power lines on the underbody are laid in a protected area to prevent damage. The electromechanical power steering is supplied with voltage differently, depending on equipment and engine. For more information on the voltage supply, refer to the F01/F02 "Voltage Supply" training material available on TIS and ICR 6 FI 0 General Vehicle Electronics 2. Voltage Supply 2.2.

EPS Voltage Supply The electromechanical power steering is supplied with voltage differently, depending on equipment and engine. In the FI 0, electromechanical power steering is combined for the first time with the active steering planetary gearbox with override function already familiar from the F01. As a result, the steering is implemented completely electrically. 8 FI 0 General Vehicle Electronics 2. Voltage Supply 2.3.1.

EPS in conjunction with active steering Due to the higher weight of the some engines and the higher steering forces associated with the greater front axle load, the power of a 12V steering system is no longer sufficient. For this reason, on FI 0 vehicles with the V8 engine a 24V EPS system will be installed in conjunction with the optional Integral Active Steering equipment. The following table tells you when a 24V EPS is installed. Engine EPS voltage supply 528i 12V 535i 12V 550i 24V EPS with 12V Since active steering demands higher forces from the electromechanical steering and due to the higher current necessary, the voltage supply can no longer be implemented as in previous systems. If active steering is used in a vehicle with 12V EPS, the voltage is supplied through a separate positive battery connection point. 10 FI 0 General Vehicle Electronics 2.

This in turn causes the power required for the steering system to increase. In conjunction with the active steering, an even higher exertion of force, and therefore an even higher current is required by the steering electrical components. This high current made it necessary to increase the voltage supply of the EPS to 24V. This system requires an auxiliary battery, a separator and a charging unit for the auxiliary battery. These components are installed in the luggage compartment of the FI 0. FI 0 24V components 12 FI 0 General Vehicle Electronics 2. Voltage Supply Index Explanation 1 Battery 2 Separator 3 Auxiliary battery 4 Battery Charge Unit (BCU) (for auxiliary battery) The battery charging unit (BCU) takes over the monitoring of the state of charge and the charging of the auxiliary battery with an 150W DC/DC converter. It monitors a cable sheathing of the 24V line (isolation) and among various other preconditions; it also switches the relay in the separator with which the auxiliary battery is integrated into the circuit. The EPS is supplied with 24V only after this relay has been switched (closed). In the event of a fault, the EPS can also be operated with 12V. If there is no fault, the relay in the separator is switched (to close the circuit) as of terminal 15. 13 FI 0 General Vehicle Electronics 2.

Car Access System The Car Access System used in the FI 0 is the fourth generation of the control unit and the same type as in the F01. The Comfort Access functions are completely integrated into the Car Access System. All FI 0 models are equipped with “Passive Go” (drive authorization system) as standard equipment. Drive authorization allows the driver to start the engine without actively using the ID transmitter. Due to the drive authorization (Passive Go), the vehicle does not require any key insertion slot. The ID transmitter only needs to be somewhere inside the passenger compartment for the engine to be started. The ID transmitter has a battery with a service life of approximately four years. Up to eight ID transmitters can be used for a particular vehicle.

Function overview The Car Access System provides, among other things, the central control unit for accessing and locking the vehicle. Therefore, the Car Access System has full responsibility for central locking. The Car Access System incorporates the following functions on the FI 0: • Comfort Access • Central locking system • Power window regulator • Glass sunroof • Terminal control • Electronic immobilizer Other functions of the Car Access System include: • Vehicle data storage • Data transmission for Conditioned Based Service (CBS) • Checking plausibility of ID transmitter signals The Car Access System enables or disables the execution of a number of functions. However, other control units may be involved in the execution of the function: • Junction box electronics • Footwell module • Roof function center • Central locking system • Power window regulator • Glass sunroof For the purposes of communication with other bus users in the vehicle electrical system, the Car Access System is connected via the K-CAN2, the CAS bus and the LIN-Bus. The Car Access System analyzes the status of the trunk lid contact switch and broadcasts it for use by the alarm system. The Car Access System also analyzes the status of the following buttons and initiates the central locking function: 22 FI 0 General Vehicle Electronics 3. Car Access System • Central locking system button • Open large trunk button on the A-pillar • Complete locking of the vehicle with the button in the underside of the open luggage compartment lid. The Car Access System provides the power supply for the brake light switch and also analyzes its status. For a more detailed description of the Car Access System functions, refer to the F01/F02 "Car Access System" training material available on TIS and ICR 23 FI 0 General Vehicle Electronics 4. Comfort Access Using Comfort Access, the customer can unlock and open the vehicle without active use of the ID transmitter. Access to the vehicle can be gained from any point. It is important that the ID transmitter be located in the vehicle's immediate vicinity (approx. 1.5 m). It is sufficient to have the ID transmitter somewhere on your person. Comfort Access was first introduced on the E65 (03/2002). The system was then gradually introduced on different BMW models. Comfort Access can be ordered as optional equipment (option 322) as part of ZCV Convenience Package (which also includes 316 Power tailgate 323 Soft-close automatic doors. The benefits of Comfort Access are: • High level of convenience when unlocking and locking the vehicle • Convenient and fast access to the vehicle • Simple engine start/stop procedure • Maximum comfort for the driver. Comfort Access in the FI 0 is based on predecessor systems and is adapted to the FI 0. However, the complete function continues to be in the Car Access System, just as in the F01. That is why the FI 0 also has no separate Comfort Access control unit. The vehicle is unlocked when your hand touches the handle recess of the outer door handle and is opened when you pull the door handle. The vehicle can be locked simply by touching sensitive surfaces of the outer door handle. For vehicles fitted with the Automatic Soft Close system (option 323), the drive for the Automatic Soft Close system fully closes the vehicle door. You can then lock the vehicle again by subsequently pressing on the sensitive surface of the outer door handle. The ID transmitter must be located in the vehicle interior in order for the engine to be started. The engine can now be started by pressing the START-STOP button when the brake pedal is operated and the vehicle is ready to be driven. 24 FI 0 General Vehicle Electronics 4. Comfort Access 4.1.

Function overview Comfort Access is divided into the following functions: • Access authorization (Passive Entry) • Drive authorization (Passive Go) • Locking authorization (Passive Exit). ID transmitters are required for Comfort Access to function. An ID transmitter incorporates the following: 26 FI 0 General Vehicle Electronics 4. Comfort Access • A battery • Remote control function • Transponder coil for emergency start function • Spare key • Receiver unit. The driver's door can also be unlocked and locked with the spare key. For a more detailed description of the comfort access functions, refer to the F01/F02 "Comfort Access" training material available on TIS and ICR 27 FI 0 General Vehicle Electronics 5. Central Locking System The central locking system makes it possible to unlock or lock the vehicle. It is fitted as standard equipment and relates to all vehicle doors, the fuel filler flap and the tailgate. The central locking can be operated via the following components: • ID transmitter • Driver's-door lock barrel (door lock) • Central locking system button • Exterior tailgate button • Interior tailgate button in the A-pillar • Outer door handle (outside door handle electronics with Comfort Access, option 322) • Button in the underside of the open luggage compartment lid for central locking system (automatic operation of tailgate, option 316). The FI 0 has no lock in the luggage compartment lid for unlocking with the mechanical or spare key. The central locking system in the F10 is based on previous central locking systems used in, for instance, the E70, E90 or F01. 28 FI 0 General Vehicle Electronics 5. Central Locking System 5.1.

Function overview The function of the central locking system is basically divided between two control units. The Car Access System has overall control. The Car Access System is aware of the statuses of the central locking system. Therefore it is the Car Access System which causes the unlocking, locking and central deadlocking of the vehicle. The junction box electronics execute the request to unlock or lock the vehicle. It is possible to unlock and lock the vehicle actively or passively. Active means that the vehicle can be opened after it has been unlocked by pressing the button on the ID transmitter. The vehicle can be locked by pressing the Lock button after the doors have been closed. A_ Note: The vehicle can only be locked with the driver's door closed. 30 FI 0 General Vehicle Electronics 5. Central Locking System Passive locking and unlocking requires the optional Comfort Access equipment (option 322). Passive means that the vehicle is unlocked when the outer door handle is grasped, provided the ID transmitter is located no more than approx. 1.5 metres away from the vehicle. The locking function is triggered by pressing on the sensitive area on the outer door handle. For a more detailed description of the locking functions, refer to the F01/F02 "Central locking system" training material available on TIS and ICR 31 FI 0 General Vehicle Electronics 6. Automatic Soft Close System The Automatic Soft Close system (SCA) can be ordered as optional equipment (option 323) on all F10 models as part of the ZCV Convenience Package. The ZCV Convenience Package also includes, Power tailgate (option 316) and Comfort Access keyless entry (option 322). The luggage compartment lid is equipped with the Automatic Soft Close system only in conjunction with the Power tailgate (option 316). The Automatic Soft Close system requires the installation of suitable door locks with drives for the Automatic Soft Close system. The special feature of the FI 0's Automatic Soft Close system is that the door lock and the drive for the Automatic Soft Close are no longer combined as a single component. The drive for the Automatic Soft Close system is separate and controls the door lock via a Bowden cable, the same as in the F01. This means that the lock and the drive can be fitted separately. With the Automatic Soft Close system, it is sufficient to press the luggage compartment lid gently into the trunk lid lock. As soon as the locking pawl reaches the pre-locking position, the Automatic Soft Close system fully closes the luggage compartment lid. The locking pawl is then located in the main locking position.

Driver's door switch cluster When the power window switch for the driver's window or front passenger's window is operated, the signal is routed via the LIN-Bus to the footwell module. The footwell module activates the corresponding power window motor. The signal is routed from the driver's door switch cluster via the LIN-Bus to the footwell module when the power window switches for the windows in the rear doors are operated. The footwell module sends the signal via the K-CAN2 to the junction box electronics. The junction box electronics receive the signal and activate the corresponding power window motor. 38 FI 0 General Vehicle Electronics 7.

Anti-theft Alarm System The anti-theft alarm system is standard equipment on all F10 models. As on previous models, the alarm system must be activated. When activated, the alarm monitors the whole of the vehicle interior. The alarm system monitors the engine compartment and the vehicle's rest position. So that nothing can be stolen from the luggage compartment, the alarm system monitors opening of the trunk lid. The alarm system also signals an attempt to tamper with the vehicle, e.g. cutting the supply line to the emergency power siren. An Ultrasonic interior movement detector is integrated in the roof function center. The ultrasonic signal passes into the inside of vehicle through apertures in the grille of the roof function center. The emergency power siren with tilt sensor is located near the rear wheel arch. For more information on the operating principle of the alarm system, refer to the F01/F02 "Anti theft System" training material available on TIS and ICR 44 FI 0 General Vehicle Electronics 9.

As soon as the status of a Hall sensor changes, the ultrasonic interior movement detector (14) receives that information via the K-CAN2. If the anti-theft alarm system is activated, an alarm is triggered. The hood contact switch (1) is monitored by the Car Access System (2). If the status changes, an alarm is triggered in the same way. Opening of the trunk is monitored by the junction box electronics (4). If the status of the trunk lid contact switch (10) changes, it triggers an alarm. 46 FI 0 General Vehicle Electronics 10. Automatic Trunk Lid The “Power Tailgate” option is offered in the FI 0 as part of the ZCV Convenience Package, which also includes Comfort Access keyless entry and Soft-close automatic doors. The automatic operation of the trunk lid improves vehicle access by enabling the luggage compartment lid to be opened or closed automatically at the press of a button. A spindle-driven system is used in the FI 0 for automatic opening or closing of the luggage compartment lid. With Comfort Access, it is even possible to open the luggage compartment lid while the vehicle is locked. Pressing the outer trunk lid button opens the luggage compartment lid automatically. The only requirement is that a vehicle-specific ID transmitter must be present in the immediate vicinity of the rear end of the vehicle. The trunk lid can also be opened by pressing the button on the ID transmitter. An open luggage compartment lid can be closed by pressing the "close trunk lid" button. Index Explanation 1 Close trunk lid button 2 Close and lock trunk lid button (deadlocking) In connection with Comfort Access, it is now also possible to deadlock the vehicle doors from the trunk lid.

Body controller area network K-CAN2 Body controller area network 2 KI.30 Terminal 30 Term. 30B Terminal 30 basic operation LIN-Bus Local Interconnect Network bus The radio signal from the ID transmitter is received by the rear window antenna. The remote control receiver in the antenna diversity module (15) forwards the signal to the Car Access System (4). The Car Access System is the master control unit for the central locking function. Once the signal has been successfully verified, the Car Access System issues a command to activate the central locking in the trunk lid. The junction box electronics (5) execute the command to activate the central locking system in the trunk lid. The junction box electronics detect the status of the trunk lid contact switch (11) for the automatic operation of trunk lid function. The status of the trunk lid contact switch is sent via the K- CAN to the automatic operation of trunk (8). The status is one of the triggering criteria for trunk lid operation. The sensors (13) and (7) in the spindle drives monitor the movement of the trunk lid. If the trunk lid is blocked while being closed, the automatic operation of trunk reverses a little if necessary to remove the obstacle. An obstruction to luggage compartment lid movement during the opening procedure causes the trunk lid to stop and it is not reversed. 49 FI 0 General Vehicle Electronics 10. Automatic Trunk Lid The control unit for the automatic operation of trunk lid monitors the power consumption of the spindle drive. A rise in current from the trunk lid being blocked results in the lid movement being stopped or reversed. 50 FI 0 General Vehicle Electronics 11.

Interior Lighting 12.1. Overview The interior lighting of the FI 0 is controlled by the footwell module FRM control unit. The footwell module is the central control unit for the interior lighting. All interior lighting outputs of the footwell module are pulse-modulated. This ensures that the interior light functions at a constant brightness level in the event of voltage fluctuations. The pulse width modulation is also used for the "soft ON/soft OFF" function. The components for the interior light in the front roof area are integrated in the roof function center and in the sun visors. The footwell lighting is located underneath the dashboard. The rear reading and interior lights are supplied with voltage via the roof function center.

Interior Lighting 12.2. System wiring diagram The system wiring diagram follows the description below and provides an overview of the full extent of all possible interior light options. The following examples describe some switching operations for the interior light. The status of the door contact (Hall sensor) in the lock (38) changes, for example, when the door is opened with the vehicle unlocked. The footwell module (1) evaluates the status and sends the request to switch on the interior light. At the same time, the door entry lighting (32) for the door that is open and the footwell lights (2, 3) are switched on by the footwell module. The status of the door contact changes again when the vehicle door is closed. The footwell module initiates the procedure to switch off the interior light. The luggage compartment lights and the lights in the luggage compartment lid (24, 46) are connected to the voltage supply via terminal 30B. If one of the luggage compartment lids is opened, the status of the tailgate contact switch changes (27). The luggage compartment lights and the luggage compartment lid light are switched on directly via the tailgate contact switch. 59 FI 0 General Vehicle Electronics 12.
