Automated Testing System for a CAN Communication Circuit

The paper presents a method for validation/testing a control area network (CAN) communication circuit used in all electronic control units (ECUs) developed in automotive industry after 2000. Using a specific hardware configuration and remotely controlled by LabVIEW. The author's presents their own vision regarding operational software algorithm implementation and integration / execution of some test cases in order to validate a CAN circuit. Using this method, it is possible to validate/test CAN hardware circuits in a short time and with the possibility of saving the test results. Human operator is interfering with the system only through the graphical user interface. The error sources for this system are reduced to minimum.
