OBD-II can use one of (many) different bus systems to transfer diagnostic data from and to your car. Think of OBD-II as a language (English) that you speak and of CAN as the communication device (telephone) you use to talk to someone (about your car and its state of health ;). The CAN bus provides a low-level interface that allows ECUs to communicate directly with each other through a simple serial bus. CAN FD, or Controller Area Network Flexible Data-Rate, is a protocol that builds upon CAN. The main difference between CAN and CAN FD is that the Flexible Data Rate in CAN FD allows for higher data throughput on the bus. CAN bus is a set of 2 electrical wires (CAN_Low & CAN_High) in the car network where information can be sent to and from ECUs. The network inside the car that allows ECUs to communicate with each other is called CAN (Controller Area Network). In Evoque, the CAN network is divided into subnetworks connected together using a Gateway Module ECU. 1 Answer. Sorted by: 4. The intent of the resistors at each end of the bus is to control transients due to time delays. The bus needs to be terminated with its characteristic impedance at each end. However if the bus is only 6 feet long I would expect your implementation with a 60 ohm resistor in the middle to work.The active bus state (called the dominant state in the CAN spec) is each line pulled only 900 mV from the idle level. The two states are therefore 0 V or 1.8 V differential, not 5 V and -5 V like RS-485. The power to keep a CAN bus in the dominant state is only 54 mW, and none at all to keep it in the recessive (idle) state.So even a CAN bus of 10cm needs termination resistors, to have correct current and voltage on the bus when driven and not driven. That's because CAN is a differential open-drain / open-collector bus, where bus lines float at recessive state unless being actively driven by a transmitter, and the transmitter will only drive CANH high and …Are you a fan of simulation games?
