Modern vehicles are already heavily networked internally by the single bus systems. Communication of vehicle occu¬ pants with the vehicle occurs via several control and display systems like the instrument cluster, on-board monitor with navigation system and on the E65 with the central Control Display. This networking in constant progress is also revolutionizing the service process. It is called "Connected Service" and allows increasing communication and networking between the vehicle and the Retail Service Departments. Customers can expect the following from the B MW Service in the future: Exactly planned appointments, no loss of information, early problem detection and flex¬ ible service. Fast handling of the service process without long waiting times for the service advisor, spare parts or vehicle. Departure from fixed items of inspection/repair, same high service quality, personal and individual advice. Connected Service offers new possibilities. Vehicle specific service requirements are auto¬ matically assessed. Fixed inspection/maintenance schedules will be replaced by more flex¬ ible maintenance services. The existing process will be further optimized, the appointment process will be faster and more effective and service advisors will have more time for individual consultation. 3 E65 Service Overview of Technical Aspects Connected Service is made up of several modules some of which are already available or are introduced starting with the E65. The modules are: Condition Based Service (CBS) CBS defines vehicle specific maintenance requirements by sensor based monitoring of engine oil, air conditioning micro-filters and the front and rear brake linings. In addition, time dependent monitoring of the engine oil, brake fluid and coolant. CBS also provides distance dependent monitoring of spark plugs as well as visual and functional checks. The service need display (SBA) is located in the instrument cluster and the details are displayed in the Control Display. Coded Keys The BMW keys have already been storing information for approximately 3 years. Since 1998 the chassis numberand since 1999 the chassis number, mileage and status of the Service Interval Display (SIA) is stored. 42 - 15-24 The E65 keys (FBD keys or remote control service keys) store more information, such as check control messages and all CBS relevant data like: mileage, oil condition, brake pad wear and microfilter condition. The key is the "business card" of the vehicle. 42 - 15-18 Key Reader The Key Reader allows readout of the data stored in the key when the vehicle is checked in for service. The required basic data of the vehicle and the data concerning all service requirements are automatically available. Service Acceptance Module Software (SAM) SAM is the software running at the service advisor work place. The software interprets and displays (processes) the data stored in the key. 4 E65 Service SAM includes two future extension levels: SAM 2 (Extension of SAM 1 - Future) Associated with TeleService 1, it allows the remote transmission of vehicle data stored in the keys and access to the central service databases (central repair history). SAM 3 (Extension of SAM 2 - Future) Associated with TeleService 2, it allows the dealerto communicate with the vehicle fortrou¬ bleshooting complex electronic problems. TeleService (Future) TeleService will be offered at two levels: TeleService 1 will allow automatic or manual data transfer by cellular phone from the vehicle to a TeleService center. The Service Call transmits wear and fault information. Emergency service calls may be placed to an assistance service center. The transmis¬ sion of information via S M S (Short M essage Service) will allow collection of data from customers. TeleService 2 will allow remote diagnosis of the vehicle electronics. Finally, Tele- Programming will allow the removal of faults, encoding and flash programming via the telephone interface. Transfer and Analysis of Vehicle Operation and Service Data (FASTA) FASTA increases product guality, gives input to Research and Development and is the basis for developing more accurate diagnostic tools and optimizing processes aimed at solving problems. In the workshop, the vehicle data is read with DISplus and transferred via net¬ work to the central FASTA vehicle related database at BMW. Starting with the E46, FASTA was implemented for the first time for a select number of dealers in Europe and in the USA. This pilot phase now is over and FASTA is now being used for the launch of all new models and as an integral part of quality control. Please refer to SIB #07 08 01 & # 07 07 01 for further details. 5 E65 Service Condition Based Service (CBS) Purpose of the System The current Service Interval Indicator systems (SIA3 and SIA4) determine maintenance intervals based on fuel consumption, which is done to assess the need to change the engine oil. The main determining factor for the maintenance interval currently is the condi¬ tion of the engine oil. Other maintenance needs, including the replacement of wearand tear items, are arranged to coincide with due engine oil changes. On the E65, B M W is measuring the need for maintenance of several critical components besides the engine oil, and independently of the engine oil. This would theoretically afford us the ability to bring a vehicle in for service whenever one of the measured components reguires maintenance or replacement. However, customers would be inconvenienced because the maintenance intervals would be dramatically reduced. Condition Based Service (CBS - further development of SIA) will strike a compromise between too freguent maintenance and too rigid intervals which call for the replacement of maintenance items that may still have substantial useful life left. The objective is to furnish economical maintenance by providing the ideal service for individual vehicles. Principle of Operation Sensor Based (CBS) Schedules The trend in the vehicle service business is to lengthen service intervals and reduce replace¬ ment of maintenance items. Additional measures have been taken to keep the vehicles in a roadworthy and comfortable condition. Usage dependent maintenance of select wear and tear items is detected by physical and virtual sensors. This means that, in cases where the wear is not measured directly, the ser¬ vice due date will be determined by using auxiliary variables such as mileage, vehicle per¬ formance, temperature, etc. Sensors built into certain components and control module algorithms take even more detailed account of the various conditions of vehicle use. The remaining times for selected maintenance tasks as well as any dates for State and/or Emissions Inspections (determined by the state in which the vehicle is registered) are individually displayed. 6 E65Service CBS thus determines the current and future maintenance requirements. The current status of Service items determined by CBS are shown in the Control Display. This data can also be read from the vehicle key by using the Key Reader, as the vehicle's current service sta¬ tus is automatically saved in the ignition key every time the key is used to operate the vehi¬ cle. 3 sensors detect the following wear conditions: Engine oil (sensor) M icrofilter (virtual sensor) Front and rear brake linings (sensor as reference point) The instrument cluster collects the values from the wear detection control modules and manages the internally defined service repair schedule. Data exchange is carried out on the bus systems. Engine Oil Condition The condition of the engine oil is detected by the oil condition sensor. Simultaneously it also detects the engine oil level and the oil temperature. The engine oil condition sensor is monitored by the ECM and is mounted in the lower oil sump. The ECM contains an algorithm for evaluating the service due date. The following parameters are considered in the calcula¬ tion: The correct oil grade is installed Fuel consumption (ti signal) Oil level Mileage Oil temperature Date (time elapsed since the last oil change) Engine load The remaining life to the next service is forwarded from the ECM to the instrument cluster by a bus message when the ignition is switched "ON." When the "engine oil" service is due, it is shown in the instrument cluster or the Control Display. Note: The instrument cluster and the ECM must not be replaced simultaneously, otherwise all current oil maintenance schedule data will be lost. 7 E65 Service Microfilters State of Wear t The air intake section of the air conditioning sys¬ tem includes a microfilter on the right and on the left. The microfilters (1) include an additional active carbon filter. The condition of the micro filter is detected by the IH KA control module. It does not include a phys¬ ical sensorto measure the level of contamination in the micro filter. The IH KA uses an algorithm to calculate this from the following parameters Ambient air temperature Heating use Driving speed M ileage Rain sensor signal Air recirculation settings Fan speed Date (time elapsed since the last oil change) The remaining life to the next service is forwarded by the IH KA control module to the instru¬ ment cluster by a bus message when the ignition is switched "ONWhen the "microfilter" service due date occurs, it is shown in the instrument cluster or the Control Display. Note: The instrument cluster and the IH KA control module must not be replaced simulta¬ neously otherwise all current oil maintenance schedule data will be lost. Front and Rear Brake Linings State of Wear The brake lining state of wear on the front and rear axle is detected by 2-stage brake lin¬ ing wear sensors. These are located on the left front and right rear brake pads. The first stage (reference point for the calculation) of the wear indicator is activated when the thickness of the lining is 6 mm, and the second when it is down to 4 mm. The brake lining wear sensors voltage signals are monitored by the DSC control module. The brake lining wear sensor operates in the first stage as on current models and a resis¬ tor was added for the second stage. 8 E65 Service The algorithm is controlled by these two different voltages in the control module and deter¬ mines the residual thickness of the brake lining. The residual wear of the brake lining is cal¬ culated from the following input parameters: Wheel speed Brake disc temperature Braking frequency Brake pressure Braking time M ileage (travel distance) The residual wear of the brake lining on the front and rear axles is stored in the DSC con¬ trol module when the ignition is switched "OFF" and is used as the starting value the next time the vehicle is started. The residual distance to the next service is forwarded by the DSC control module to the instrument cluster by a bus message when the ignition is switched "ON." The "Front or Rear brake linings" service due date is displayed in the instrument cluster or the Control Display. Note: The instrument cluster and the DSC control module must not be replaced simulta¬ neously, otherwise all current oil maintenance schedule data will be lost. Internal Calculation of CBS Service Volumes For certain wear and tear items, sensors are not needed by the Condition Based Service. The wear items that are calculated and managed internally by the instrument cluster are: Brake fluid Coolant Spark plugs Visual and functional checks (vehicle check) Official State safety and/or emissions inspections The maintenance of these items is performed at fixed intervals. The residual wear or the remaining time to next service is calculated by the instrument cluster using the travel/time parameters of: mileage, current date and internal distance counter. When a service item is due, it is shown in the instrument cluster or the Control Display. Note: The internal distance counter plays a particular role. Unlike the Time/Date, this counter cannot be set by the driver. 9 E65 Service However, battery down times (battery cut off by the distribution switch) also stop the trip distance counter which leads to longer time based service intervals. This will disrupt the CBS volumes for engine oil, microfilter, brake fluid and coolant. To correct this, the internal counter status must be reset by the DISplus. The wear depen¬ dent items internally calculated by the instrument cluster are stored in the instrument clus¬ ter and in the CAS control module (redundancy). Note: The instrument cluster and the CAS must not be replaced simultaneously otherwise all current oil maintenance schedule data will be lost. Service Indicators Regarding CBS, there are three different service indicators: Service need display (SBA) in the instrument cluster (base of speedometer) Check Control display in the instrument cluster (base of tachometer) CBS indicator in the Control Display Service Need Display (SBA) The Service Need Display is the evolution of the SIA4 Service Interval display. When KL15 is "ON," the Service Need Display appears underthe speedometer in the instrument clus¬ ter for 10 seconds in the place where the fuel tank level is normally displayed. The first line corresponds to the mileage depen¬ dent service items. It specifies the mileage when the next service is due. If the mileage is exceeded (service overdue), it appears with a minus sign. The second line corresponds to the time dependent service items and is displayed by a clock symbol. It specifies the weeks/months/ years when the next service is due. If the service is overdue, it appears with a minus sign. 42 - 15-01 The actual service item (with additional information) can be viewed in the Control Display. 10 E65 Service Check Control Message The CBS produces a Check Control message that indicates the brake lining wear at the front or rear axle. When the brake linings are worn, this is shown as follows: The general brake warning lamp and the vari¬ able control lamp come on in the instrument cluster. The variable control lamp shows the symbol of a car on a lifting platform. In the base of the tachometer is a Check Control message that appears in short form: "Service, see Vehicle menu." For more detailed information, the user can access the Control Display. CBS Indicator in the Control Display The Control Display provides additional infor¬ mation on service and maintenance procedures by selecting the "OB data" menu. After releasing the Controller or returning to the central position, the "On-board data" menu appears. Turn the Controller to the left until the bottom left button is highlighted (vehicle symbol).
