Bodywork interface
Description
A more detailed description of the electric bodywork interface is found in the docu-ment Installation instructions.

DescriptionBodywork interfaceThe electrical system in Scania vehicles is based on a number of control units that communicate with each other via a common network.

To use existing technology, a bodywork interface is provided which uses traditional (+24 V and ground) and analogue signals. The bodywork interface consists of a num-ber of connections which carry the electrical signals and functions that are available to bodywork.

The basic range in the Scania bodywork interface is presented in this document.

BCI (Bodywork Communication Interface)Scania recommends that a bodywork control unit with functionality with variant code 5837A is ordered as an option. The bodywork control unit provides the follow-ing if 5837A is added:

• An expanded range and selection options regarding signals and functions

• The option of programming a number of outputs with optional signals

• The possibility of remotely controlling certain vehicle functions and access to conditional output signals.

• The possibility of using expansion units to extend the bodywork interface. The expansion unit can, for example, be fitted on the bodywork to minimise the rout-ing of cables into the cab.

• Program, save and reuse function connections in BICT (Bodywork Interface Con-figuration Tool).

• 5837A also provides the possibility of selecting additional functionality, such as, Automatic neutral and Remote engine start.

Bodywork interfaceSwitches

More information on switches can be found in the document Switches for bodybuild-ers

SwitchesSwitches in instrument panelThe space available for bodywork switches in the instrument panel depends on the type of instrument panel and the amount of equipment fitted at the factory.

Cables for connecting additional switches must normally be installed by the body-builder. Prepared cables with connectors for four (4) bodywork switches are availa-ble as an option.

Switches in roofshelfIt is possible to fit switches in the roofshelf depending on what equipment has been fitted at the factory. A cable harness with 10 conductors to the roofshelf, which can be used for connecting the switches, is available as an option.

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

More information on status and warning signal installation is found in the document Installation instructions.

Indications in ICL for bodywork functionsThe instrument cluster is prepared with options for connecting indicator lamps, dis-play messages and acoustic signals for bodywork functions. The indicator lamps can be controlled via +24 V, a ground connection, BIC (Bodywork Interface Configura-tion) or External CAN. For BIC and External CAN the BCI functionality is also re-quired.

The function is ordered with the option Preparations for indicator lamps and display messages in ICL.

Instrument cluster ICL 2The functions are ordered as option with variant code 3888A. ICL 2 contains the fol-lowing options:

• 10 lamp positions1 prepared for the connection of indicator lamps. The indicator lamps and cable harnesses are fitted at the factory.

• Display messages

• Connecting acoustic signals for different needs

Adapted symbols and coloursIn front of the indicator lamps there is a removable symbol lens. Some symbols are pre-printed from the factory based on customer selection.

The bodybuilder can use own symbols or text. A sheet with pre-defined symbols can be purchased from Scania dealers.

• In ICL 2, the lamp parameters can be set in 4 different colours depending on lamp position – blue, yellow, green or red.

1. Certain places may be occupied depending on the vehicle's configuration.

More information on different cable harnesses for bodywork can be found in the doc-ument Installation instructions.

Cable harness as optionIt is possible to select different cable harnesses from the factory to facilitate work on the bodywork.


22:10-019 Issue 2.1 en-GB 18 (19)

Bodywork interfaceExternal CAN, CAN bodywork interface

More information on the CAN interface is found in the CAN bodywork interface doc-ument.

External CAN, CAN bodywork interfaceOne of the main advantages of the bodywork interface is that it allows connection to the vehicle's CAN interface via the bodywork control unit. This enables the body-builder to control functionality by reading information (output signals from the vehi-cle) and sending information (input signals to the vehicle).

Connection point of External CAN for bodywork is done via connector C493. Exter-nal CAN is part of the BCI functionality option and can be ordered from the factory.

Information sent from the vehicle via External CAN includes not only the signals in the existing connectors but also much more. By using the External CAN interface, connections, especially those with multiple functions, can be simplified.

Most functions can be controlled via External CAN.

C137 ConnectorThe FMS standard is an open, common interface developed by several truck manu-facturers. FMS (Fleet Management System).

Connector C137 is located under the central electric unit in the instrument panel.
