Speedometer

Two variants of the speedometer are availablefor the BMW 3 Series. The signal chain isidentical to the signal chain of the rev counter.

Rev counter

On the BMW 3 Series, engine speed isdisplayed using the following signal chain:

• The DME control unit sends the enginespeed on the PT-CAN and K-CAN.

• 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.

3 The engine speed range is increased to7500 rpm on vehicles equipped with 6-cylinder petrol engines. 1

Economy control (fuel consumptionindicator)

The economy control is an analogue indicatorin the instrument cluster.

Fuel gauge

The 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.

Outside temperature display

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.

The instrument cluster makes available thecurrent outside temperature in the form of adata telegram via the K-CAN.

Indicator and warning lamps

The indicator and warning lamps are activatedby the processor in the instrument cluster.

All important and legally stipulated indicatorand warning lamps are activated at terminal 15ON during the pre-drive check.

The 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.

Condition Based Service (CBS)In the same way as the mid-range and luxurymodels, the BMW 3 Series will also be offeringservice intervals that are geared towards thecurrent condition of selected components, i.e.servicing that depends on the condition ofcomponents and maintenance requirements;this is known as Condition Based Service(CBS).Condition based service therefore means -servicing only when a part is worn.

The system calculates when a serviceoperation, e.g. an oil change is due andinforms the customer of this via the LC displayin the instrument cluster.

CBS sorts all the data according to date dueand can determine when the vehicle should betaken into service.

If a central information display CID is installed,the instrument cluster passes on the sorteddata to the CID where the data can bedisplayed in the service menu.

There are ten different types of service, witheach of these types being assigned to aspecific service group, e.g. oil change.

The system comprises the followingcomponents with their sensors:

• Instrument cluster

• External control units such as DME, IHKAand DSC

• Car Access System (CAS) 2

• Central information display CID.

Block diagram EU

All information that the CBS system requires issent on the K-CAN bus .

The CBS requests from all the control unitsare therefore sent via the K-CAN to theinstrument cluster and to the CentralInformation Display.

Component replacement and trialreplacement

There are three possible combinations forreplacing the instrument clusters and caraccess system 2 CAS 2.

• Instrument cluster defective,CAS 2 OK

• CAS 2 defective, instrument cluster OK

• CAS 2 and instrument cluster must bereplaced.

Simultaneous replacement of CAS 2 and theinstrument cluster should be avoided. Theodometer reading will be lost as a result.

In principle, it is also possible to carry out a trialreplacement of the instrument cluster andCAS 2.

To select check control messages in theinstrument cluster

The instrument cluster shows a series ofvehicle statuses and consequently generatesCC messages.

The following procedure must be performedto select a CC message:

1. Press the rocker switch in the steeringcolumn stalk up or down until the "CheckControl" function appears in theinstrument cluster.

2. Press the BC button on the steeringcolumn stalk and confirm the display.

3. Press the rocker switch up or down toselect the CC messages.

4. Press the BC button on the steeringcolumn stalk to exit the menu.

3 The outside temperature or a previouspriority 1 message is displayed again if therocker switch is not operated for 8 seconds.1

SummaryDisplays, Indicators and Controls

Points to remember

The most important information concerningthe display, indicator and control concept inthe BMW 3 Series is summarized in thefollowing table.

The list is intended to provide you with thecontents and important points of thisParticipant's Manual in concise form.

Theoretical and practical notes forday to day use.

Operating concept

It is possible to operate all comfort functions and several vehiclefunctions via the controller in the BMW 3 Series.

Instrument cluster

A classic two-dial design draws attention to both instruments.

Compact display and indicator units convey the most importantinformation to the driver at a glance.

The instrument cluster has no gateway function as on the previousmodel series.

Only the outside temperature, the information from the steeringcolumn switch cluster and footwell module are shown directly in thedisplay.

In the High variant, the set speed for the cruise control is realized by amoving dial indicator.

The moving dial indicators are located directly behind thespeedometer and rev counter scales.

45

8

The analogue indicator for the fuel reserve is located in the instrumentcluster.

The fuel reserve level is not indicated by an indicator lamp as in theprevious models.

A fuel pump symbol is illuminated for 23 seconds in the LC display assoon as the reserve level of 8 or 6.5 litres respectively is reached. Thisdisplay is permanently activated at a range below approx. 50 km.

Operating concept - steering column stalk

A graphic symbol in the upper display window is assigned to eachmain menu item.Menu items that are deactivated during vehicle operation are notshown.

Each menu can be interrupted at a certain position by briefly pressingthe BC button.

Depending on the equipment variant and on the radio/navigationsystems, several menu items are blanked out and can therefore onlybe adjusted via an external control unit. The display for the M-ASK andCCC are shown on the central information display CID.

Central information display

The new BMW 3 Series offers the same convenient operating andcontrol functions as the mid-range and luxury BMW models.

The central information display CID is designed the same as the CIDinstalled in the BMW 5 Series and BMW 7 Series.

The user interface in the CID is identical to that of the CID installed inthe BMW 5 Series.

Personal Profile

Through the Personal Profile, the BMW 3 Series also caters for thedriver's personal requirements.

The Personal Profile allows the driver to set several functions of theBMW 3 Series to suit his/her personal requirements.

Personal Profile stores the data entered by the driver such asautomatic setting of the outside mirrors or speed-dependent volumein the corresponding control units.
