Requirements for CAN communication with the vehicle
11:90-01 Issue 1 en-GB 132 (139)
It is the responsibility of the bodybuilder to ensure that the bodywork control unit
does not receive contradictory commands. If, for example, the bodywork control unit
gives a command that sounds the horn, no other control unit that gives commands to
the engine may give contradictory commands to the horn. One way of solving this
problem is to use a topology as shown in the diagram. Control unit X collects, com-
pares and collates the information before the commands are sent to the bodywork
control unit. In this case only two messages - Scania Bodywork Message 1 and 2 -
are sent to the bodywork control unit with control unit X as the source address.
