GB18352.3-2005 OBD On-Board Diagnostic (OBD) system Requirement All vehicles must be equipped with an OBD system so designed, constructed and installed in a vehicle as to enable it to identify types of deterioration or malfunction over the entire life. The tests t are carried out on the vehicle used for the Type.
GB18352.3-2005 OBD OBD system must indicate the failure of an emission-related component or system if that failure results in emission exceeding the OBD limits. for positive-ignition the efficiency of the catalytic converter (HC only oxygen yg sensor deterioration misfire related electric parts, evaporative emission purge control system. for compression-ignition DOC (Trap) devices electric control fuel injection system, emissionrelated electric parts.
GB18352.3-2005 In-service conformity check The manufacturers must take measures to assurance the function of anti-pollution device under the normal conditions. Assurance period: for China, 5years or 80000 km; for China, 5 years or 100000 km In-service conformity check is mainly finished by manufacturers, the Government will check randomly.
GB18352.3-2005 COP Check Check items Type more than 3 units, the test statistic will become the decision i value. Type Type IV OBD
