The Fault Diagnosis of Car Body Control System Based on the CAN Bus

Abstract:

A solution to the Car body fault self-diagnostics based on CAN bus is developed. It completes the fault diagnosis communication between the body controller and the diagnostic apparatus by treating the ISO15765-2 as the network layer, and the ISO14229 as the diagnostic application layer. The parameters and services of the two standards are customized to the needs and characteristics of the body control system. Finally, the diagnostic programs of the corresponding body control module and the upper computer are compiled and tested. Satisfactory results are achieved.
