Does anyone knows which modules/systems are connected to the CAN Bus circuit of the vehicle listed above? And where the terminating resistors are located? A diagram of the CAN Bus circuit would be great. Thanks

That car has two different CAN networks, The Fast-CAN and the Body-CAN. They both go to the various modules for control but Honda/Acura doesn't show the topography for the networks in the service information we have. A good scan tool might show the layout and modules for each system but it may not unless it is Hondas own scan tool.
The F-Can is used for engine, trans and other systems that use high speed. The B-Can is for things like the windows, door locks and such, but they somewhat overlap as well.
