Design of OBD function test on production vehicle (PVE)

Abstract

Production Vehicle Evaluation (PVE) test mainly verifies the functionality of OBD system. PVE J2 test needs to verify the diagnostic mechanism for all the diagnostic Trouble Codes (DTC). While the design of fault simulation method is one of the technical difficulties of the whole PVE test. Due to the late start of PVE in China, test methods and technical skills are inadequate. This paper elaborates the failure monitoring principle and diagnosis mechanism of OBD system in detail,systematically introduces the PVE methods and J1, J2, J3 test procedures, studies and analyses the types of OBD malfunction and various fault simulation methods,finally forms a set of PVE test specifications.

Machine Learning Approaches for In-Vehicle Failure Prognosis in Automobiles: A Review

“…This implies that the OBD system must capable of recognize defects, activate MIL, and save the relative approved and permanent fault codes. The main goal of the J3 test is to gather the inuse monitoring performance tracking ratio (IUPR) [18]. In one study, data from the sensors is gathered, and then a fusion approach is used to assess the outcomes.…”
