CAN interface for bodywork
Requirements for CAN communication with the vehicle
11:90-01 Issue 1 en-GB 135 (139)
Termination resistors
The CAN bus cable (main cable) must be connected using a 120 Ohm resistor at each
end in accordance with SAE J1939-15 Physical Layer "Light". A split termination re-
sistor (2 resistors and a capacitor) fitted in the bodywork control unit. See the figure
below. There must also be a termination resistor in the control unit installed furthest
away from the bodywork control unit (see the figure on the previous page). Scania
recommends a split termination resistor. If the control unit installed furthest from the
bodywork control unit is not equipped with an internal termination resistor, the resis-
tor must be connected as close to the control unit as possible (see figure).
