GeneralBodywork communication interfaceThe electrical system is based on a number of control units that communicate with each other via a common network. Bodywork functions are controlled by the control units, either by using analogue signals or external CAN network.

BCINote:For full BCI functionality (Bodywork Communication Interface), it is recommended that the vehicle is factory-fitted with the option Bodywork communication interface (BCI) (variant code 5837A). Retrofitting a BCI control unit and cable harness involves very extensive work. Con-tact a Scania dealer for more information.

General

Bodywork interface

BCI functionality offers the following possibilities:

• Larger range and more choices for signals and functions.• Access to conditional output signals.• Programming of a number of outputs with optional signals.• Remote control of a number of vehicle functions.• Pre-conditions to select additional functionality such as Automatic neutral and

Remote engine start.• Use of expansion units on the frame, which reduces the number of cables from

cab to frame.• Programming and re-use of logic diagrams in BICT (Bodywork Interface Config-

uration Tool).

The signals and functions available depend on the vehicle specification and year of manufacture. A complete list can be found in the BICT program.

More information on options can be found under the heading Ordering options.

EXT switchThe EXT switch is a spring-loaded, programmable switch with a symbol and an in-dicator lamp, see illustration.

Some safety-critical remotely activated functions cannot be activated before the EXT switch has been activated. This is a general safety function which is used for a num-ber of bodywork functions. When the indicator lamp in the EXT switch is on, remote activation is possible.

More information can be found in the document EXT switch.

The lead through is located on the passenger side. The illustration shows the location in a left-hand drive vehicle.

Lead through in cab floorIn all trucks, there is a lead through on the passenger side between the cab floor and bulkhead, see illustration. The lead through is dimensioned for a wide range of cable dimensions and is large enough for a connector with a diameter of approx. 70 mm to be passed through it. The lead through is located with the bellows facing out from the cab.

More information is found in the document Working with cables and lead throughs.


Switch

SwitchSwitches in instrument panelThe number of places for bodywork switches in the instrument panel varies depend-ing on the vehicle specification.

Prepared cables with connectors for 4 bodywork switches are available as an option.

More information on the option is found in the document Cable harness for addition-al switches.

Switches in roof shelfDepending on the vehicle specification, it is possible to fit switches in the roof shelf. A cable harness with 10 conductors to the roof shelf, which can be used to connect switches, is available as an option.

More information on the option is found in the document Cable harness for body-work functions in roof shelf.

Switch modulesThe switches have illuminated symbols which can be connected to a dimmer function for background lighting of switches in the instrument panel.

More information on switches is found in the document Switches.


Indications in instrument cluster (ICL) for bodywork functions

Bodywork interface

Indications in instrument cluster (ICL) for bodywork functionsOption for indications in the instrument cluster gives the option of activating acoustic indications, light indications and display messages for bodywork functions in the in-strument cluster, ICL. Indications in the instrument cluster can be controlled using analogue signals or external CAN network.


The display messages have pre-defined text that cannot be changed.

In front of the light indication positions, there is a removable symbol lens with a sym-bol for each bodywork function. Scania offers symbol lenses with different set of symbols. The parts are available from Scania dealers.



Bodywork interface

The following functionality is available depending on the options:

• Acoustic indications and 2 light indications:– Available on all vehicles.– Can always be controlled using analogue signals.

• 8 light indications1 and display messages:– Requires the option Bodywork communication interface (BCI) (variant code

5837A).• Full functionality for acoustic indications, 8 light indications and display messag-

es:– Requires the options Bodywork communication interface (BCI) (variant code

5837A) and Bodywork information in the instrument cluster (variant code 3888A?).

Instrument cluster (ICL)The instrument cluster (ICL) contains the following options:

• Connections to 8 light indication positions1 for light indication. Light indication positions and cable harnesses are fitted at the factory.

• Display messages.• Connection of acoustic indication for various needs.

Adapted symbols and coloursA removable symbol lens is fitted in front of the light indication positions; see illus-tration. Some symbols are pre-printed from the factory based on the vehicle specifi-cation.

The bodybuilder can use their own symbols or text. Sheets of finished symbols can be purchased from Scania dealers.

The parameters for the light indications in the instrument cluster (ICL) can be set to show a blue, yellow, green or red light depending on the lamp’s position. The setting of the parameters is done by using SDP3 for bodybuilders.

Information on renewing the symbol lens can be found in the document Indications in the instrument cluster, ICL.

1. Depending on vehicle configuration, certain positions may be occupied.


External CAN network, CAN bodywork interface

Bodywork interface

External CAN network, CAN bodywork in-terfaceA great advantage with the bodywork interface is the possibility to connect to the ve-hicle’s CAN interface via the BCI control unit. By using an external CAN network, connections can be simplified, especially those with multiple functions.

An external CAN network makes it possible to control functionality by reading in-formation (output signals from the vehicle) and sending information (input signals to the vehicle). Information sent from the vehicle via an external CAN network includes not only the signals in the existing connectors but also much more.

Connect an external CAN network via connector C493 in the bodywork console. CAN interface for bodywork is included in the option Bodywork communication in-terface (BCI) (variant code 5837A), which can be ordered from the factory.

More information on the CAN interface can be found in the CAN interface for body-work document.

Harness-to-harness connector C137The FMS standard (Fleet Management System) is an open, shared interface devel-oped by several truck manufacturers.

Connector C137 gives access to signals for FMS and is located behind the main cen-tral electric unit in the instrument panel.
