1 General information on the functions General information on the functions Scania offers 4 functions for limiting speed. The functions are used to meet customer and statutory requirements regarding, for example, refuse vehicles, fire engines and tractors for transporting heavy goods. Speed limiter 1 is a standard function and is fitted to all vehicles. Speed limiters 2 and 3 Dynamic speed limiter via External CAN All speed limiters can be activated without having to meet any specific safety conditions. Speed limiter 2 and Speed limiter 3 are set by SDP3 (Scania Diagnos & Programmer 3). Order of priority between the speed limiters It is always the activated speed limiter with the lowest set value that controls the speed limiting of the vehicle. The value for Speed limiter 1 is always the vehicle's maximum permissible speed. The following settings apply for emergency vehicles: The value for Speed limiter 1 must be set to the maximum speed permitted when responding to emergency calls. The maximum permitted speed for normal emergency vehicle operation is set with Speed limiter 2 or 3. 22: Issue 2.1 en-gb 1 (8)

2 General information on the functions Activation method Speed limiter 1 Speed limiter 1 is always activated when the vehicle is delivered. The function cannot be deactivated. Most vehicles are delivered with a default setting of 89 km/h. The value can be changed at a Scania workshop. Speed limiters 2 and 3 Speed limiters 2 and 3 are activated via BIC (Bodywork Interface Configuration) and External CAN. Note: There are four (4) speed limiters. Speed limiter 1: Always active, usually set to 89 km/h Speed limiter 2: Can be activated via BIC and External CAN (BodyWorkVehicleControl:StaticVehicleSpeedLimitRequest), the speed limit is set by a parameter. Speed limiter 3: Can be activated via BIC and External CAN (BodyWorkVehicleControl:StaticVehicleSpeedLimitRequest), the speed limit is set by a parameter. Dynamic Speed limiter: Can be activated via External CAN (BodyworkVehicle- Control:DynamicVehicleSpeedLimitRequest), assumes the value sent in the signal. 22: Issue 2.1 en-gb 2 (8)

3 Chassis conditions Chassis conditions Vehicle production period Preparations from the factory Production site Chassis serial number Option Alternative Variant code BCI functionality With 5837A Södertälje Speed limiters 2 and 3 With 3821A Zwolle Angers If required Bodywork cable harness from cab to frame pin 2411F São Bernardo do Campo Bodywork cable harness in frame 2 m 3023A 8 m 3023D 12 m 3023C 22: Issue 2.1 en-gb 3 (8)

4 Chassis conditions Parameters that can be adjusted using SDP3 If there is no access to SDP3, contact a Scania dealer. The parameters are adjusted under functions in SDP3. Parameter Possible value From factory Group Vehicle speed limit km/h 10 km/h Performance Vehicle speed limit km/h 50 km/h More information on the parameters is found under Adjustable parameters. 22: Issue 2.1 en-gb 4 (8)

5 Example of activation of the function Type of activation BIC (Bodywork Interface Configuration) External CAN Activation method Via pin in C259 or another signal in BIC. BodyWorkVehicleControl:StaticVehicleSpeedLimitRequest BodyworkVehicleControl:DynamicVehicleSpeedLimitRequest 22: Issue 2.1 en-gb 5 (8)

6 Example of connection using BICT, +24 V and ground for speed limiters 2 and V 2 This description shows a connection inside the cab. Information on how to make the connection with an extension harness on the chassis is found in the document Cable harness cab and frame (22:10-080). 3 1 Proceed as follows: 1. Connect the activation cable to any input pin in connector C Using BICT (Bodywork Interface Configuration Tool), the function is allocated to the selected pin. C259 C The function is ready for activation. Part information and connection positions Activation by +24 V For example, a switch Connected with +24 V or ground to any pin on C259 2 Fuse 5 A Fitted by the bodybuilder 3 Cable The cable cross-section must be min mm² Fitted by the bodybuilder The parts can be purchased from a Scania dealer C259 C Activation by grounding 22: Issue 2.1 en-gb 6 (8)

7 Signal type Pin (BWE) Activation method +24 V to selected pin on C259 BCI master C-pin (1 10), High or low Activate speed limiter or Grounding of selected pin on C In BICT The pin selected to activate the function 2. Function: Speed limiter activation 22: Issue 2.1 en-gb 7 (8)

8 Connection via External CAN This description shows a connection inside the cab. Information on how to make the connection with an extension harness on the chassis is found in the document Cable harness cab and frame (22:10-080). To be able to make a connection via External CAN, the following is required: The vehicle is equipped with BCI functionality and other functions required as options under the Chassis conditions heading. The parameter for External CAN is activated C493 C The connection is made directly to connector C493 (External CAN-low to pin 3 and External CAN-high to pin 4) Signal type CAN Activation method BodyWorkVehicleControl:StaticVehicleSpeedLimitRequest BodyworkVehicleControl:DynamicVehicleSpeedLimitRequest Activation via External CAN The parts can be purchased from a Scania dealer. More information on CAN is found in the CAN documents under Electrical systems. 22: Issue 2.1 en-gb 8 (8)
