Abstract： An Experimental System of Vehicle can bus for training and teaching purpose based on J1939 protocol was established. The system hardware was composed of notebook, Kvaser CAN bus analyzer and CAN bus modules including meter board module, vehicle body modules, engine ECU module and so forth. And the system operating interface was using X-analyser，an CAN analyzing and simulating software, with high layer protocol test results displayed on screen. This system can measure dynamic J1939 signals and output graph accordingly.
Key words：J1939 protocol, vehicle CAN bus, experiment system
