Bodywork interface

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 (based on CAN protocol).

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.

BWS (Bodywork System)Scania recommends that a bodywork control unit (BWS) be ordered as an option. The bodywork control unit offers the following:

• An expanded range of preset signals and functions

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

• A number of safe and tried-and-tested factory solutions for safety-critical func-tions, such as starting the engine and controlling engine speed from outside the cab

• The possibility for the bodybuilder to make connections to the vehicle CAN net-work, which in some cases can significantly reduce the number of electrical con-ductors, relays and fuses

Cable grommet in cab floorThere is a cable grommet to the cab in the intermediate section between the floor and the firewall on the passenger side on all trucks.

The cable grommet is designed for a wide range of cable dimensions and is big enough to feed through a connector with a diameter of approximately 70 mm. The cable grommet is located with the bellows facing out from the cab.

Right-hand drive vehiclesOn right-hand drive vehicles, the cable grommet is located on the left-hand side of the cab, i.e. reversed compared to the illustration.

Bodywork interfaceSwitches

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

SwitchesSwitches in instrument panelAvailable space in the instrument panel for bodywork switches depends on the type of instrument panel. The design depends on whether the instrument panel is short or long and on how much equipment was fitted at the factory.

Cables for connecting additional switches must normally be installed by the body-builder. Prepared cables with connectors for four bodywork switches are available 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 wires for the roofshelf which can be used for connecting switches is available as an option.

Switch symbolsThe switches have illuminated symbols which can be connected to the dimmer func-tion.

Bodywork interfaceCAN interface for bodywork

More information on the CAN bodywork interface can be found in the CAN bodywork interface document.

A description and illustrations for C137 are found in the Connectors for FMS – CAN document under Electrical system

CAN interface for bodyworkOne 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).

The connection point for the CAN bodywork interface is found in connector C259 and supplements all the connectors which are located on the bodywork console. In-formation sent from the vehicle via CAN includes not only the signals in the existing connectors but also much more. By using the CAN interface, connections, especially those with multiple functions, can be simplified.

All BWS functions can be controlled via CAN.

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

Scania’s FMS interface is referred to in this document as RTG. The bodybuilder’s own FMS network is linked to that control unit via a connector.

As from October 2013, FMS 3.0 is supported.

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