6SpeedometerOutside temperature displayTwo variants of the speedometer are availablefor the BMW 3 Series. The signal chain isidentical to the signal chain of the rev counter.A temperature sensor measures the outsidetemperature and displays it in the instrumentcluster.In ignition key position 0, the instrumentcluster applies terminal 30g current to thetemperature sensor every 10 minutes.VariantUnitECE, JPN km/hUK, USmphkm/hReading0 20 40 60 80 2600 20 40 60 1600 20 40 60 80 . 260The instrument cluster makes available thecurrent outside temperature in the form of adata telegram via the K-CAN.Rev counterIndicator and warning lampsOn the BMW 3 Series, engine speed isdisplayed using the following signal chain:The indicator and warning lamps are activatedby the processor in the instrument cluster. The DME control unit sends the enginespeed on the PT-CAN and K-CAN.All important and legally stipulated indicatorand warning lamps are activated at terminal 15ON during the pre-drive check. Using a characteristic curve, step pulses foractuating the stepper motor are assigned tothe effective engine speed.There are two variants of the rev counter forvehicles with 4-cylinder engines: On petrol engines, up to 7000 rpm On diesel engines, up to 5500 rpm.3The engine speed range is increased to7500 rpm on vehicles equipped with 6cylinder petrol engines. 1Economy control (fuel consumptionindicator)The economy control is an analogue indicatorin the instrument cluster.2 - Indicator and warning lamps - Basic variantFuel gaugeThe fuel level is indicated by a pointerinstrument integrated in the speedometer onthe left.A pictogram of a fuel gauge lights up in theinstrument cluster when the level drops belowa factory-coded threshold (standard 8 lpetrol, 6.5 l diesel).A warning tone additionally sounds onreaching the reserve threshold.3 - Indicator and warning lamps - High variantThe indicator and warning lamps can beilluminated in different colours orcombinations.The significance of the indicator and warninglamps as well as the colour assignments aredescribed in detail in the BMW 3 SeriesOwner's Handbook.26

6LC displayProgram and gear displayThe LC display is divided into two areas.The program and gear display is shown in thebottom window in the LC display on vehicleswith automatic or manual transmission.The time and outside temperature are shownin the upper display along with the CCmessages and CBS images.The on-board computer functions, CBSmessages, distance recorder as well as theprogram display for automatic transmissionare shown in the lower display.The program and gear display shows lettersand numbers. The program mode is displayedall the time and is not overwritten by otherinformation.On manual transmission vehicles, the geardisplay is blanked out by means of the codingand an enlarged version of the BC display iscoded instead of it.6 - Program and gear indicator - Basic variant4 - LC display - Basic variant7 - Program and gear indicator - High variantAcoustic generatorsAudible warnings are given in support of checkcontrol messages. The instrument clustercontrols these warnings via the K-CAN. Thewarning signals are output by the MASK/CCCcontrol unit when installed as an option.5 - LC display - High variantManipulation dotDifferent data are stored in the instrumentcluster and in the CAS when a dot appears tothe left of the trip distance recorder.The acoustic generator in the instrumentcluster sounds the warnings if radio 1 or radio2 is installed in the vehicle.The footwell module is responsible for controlof the direction indicator function via the KCAN.The manipulation dot is indicated when, forexample, comparison of the stored vehicleidentification number does not agree.3Different data may be caused, forexample, by replacing on of these two controlunits. 127

6Lighting/dimming of display instrumentsThe instrument cluster is illuminated in thelights ON setting.The instrument cluster calculates thebrightness of the lighting (dimming) of thedisplay, pointer instruments. The brightnesssetting is distributed over the K-CAN to furthercontrol units such as the CID in the vehicle.When the vehicle lighting is switched on, thedimmer control is matched with thephototransistor integrated in the instrumentcluster. The lighting intensity can be setindividually in the BC menu via the rockerswitch on the steering column.288 - Setting lighting/dimmer via the steering column stalkWhen the vehicle lighting is switched off, thesystem is controlled only by thephototransistor so that the display brightnessis determined by the ambient light.

6US variantThe main difference compared to the EU LHDinstrument cluster is in the speed scale whichshows both mph (miles per hour) and km/h(kilometre per hour).In addition, fuel consumption is shown in mpg(miles per gallon).9 - Instrument cluster, US variantThere is a further difference compared to theEU variant in the arrangement andrepresentation of the indicator and warninglamps.The following symbols are replaced by words:SymbolWordsAudible warningsUS vehicles additionally feature an ignition keywarning and a seat belt warning.An uninterrupted warning tone sounds whenthe driver's door is opened with terminal 15OFF and the identification transmitter in place.The audible signal is switched off by removingthe identification transmitter, closing the dooror after 30 minutes.The seat belt warning is activated at terminal15 ON if the seat belt contact is not closed.The audible warning is intermittent and is nolonger than 6 seconds. The indicator andwarning lamp remains on.3The indicator lamp for the rear fog light isnot active in the US variant. 129
