Design of OBD function test on production vehicle (PVE)

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