Research on Vehicle’s Combination Dashboard Diagnostic Protocol Stack

As the development of Vehicle Electric and Electrical system, Vehicle’s digital Combination Dashboard which can be used to learn about the whole vehicle’s parameters by driver has made an important role in the reliability of whole vehicle. So it is necessary for us to acquire the whole vehicle’s parameters and faults by realizing the on line and off line diagnosis of the combination dashboard. This paper develops a diagnostic design approach for vehicle’s digital combination dashboard on the basis of ISO 15765. It has realized the on line and off line diagnosis for vehicle’s combination dashboard in order to detect the vehicle’s parameters and faults conveniently. The experiment proves that the diagnostic protocol stack is efficient and reliable, it can greatly increase the speed of maintain service for engineers.
