Description Description Bodywork interface The 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 number of connections which carry the electrical signals and functions that are available to bodywork. A more detailed description of the electric bodywork interface is found in the document Installation instructions. 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 following 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 routing of cables into the cab. Program, save and reuse function connections in BICT (Bodywork Interface Configuration Tool). 5837A also provides the possibility of selecting additional functionality, such as, Automatic neutral and Remote engine start. 22:10-019 Issue 2.1 en-gb 1 (19)
EXT switch EXT switch Critical remote-activated functions are blocked until the driver has enabled remote activation with the EXT switch. This is a safety function which is used for a number of bodywork functions. Remote activation enabled is indicated by the EXT lamp coming on in the instrument cluster. 315 587 22:10-019 Issue 2.1 en-gb 2 (19)

External CAN, CAN bodywork interface One 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 bodybuilder to control functionality by reading information (output signals from the vehicle) and sending information (input signals to the vehicle). External CAN, CAN bodywork interface More information on the CAN interface is found in the CAN bodywork interface document. Connection point of External CAN for bodywork is done via connector C493. External 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 Connector The FMS standard is an open, common interface developed by several truck manufacturers. FMS (Fleet Management System). Connector C137 is located under the central electric unit in the instrument panel. 22:10-019 Issue 2.1 en-gb 19 (19)
