  § 16-3340.42. Smog Check Test Methods and Standards.  

Latest version.
  • Smog check inspection methods are prescribed in the Smog Check Manual, referenced by section 3340.45.
    (a) All vehicles subject to a smog check inspection, shall receive one of the following test methods:
    (1) A loaded-mode test shall be the test method used to inspect 1976 - 1999 model-year vehicle, except diesel-powered, registered in the enhanced program areas of the state. The loaded-mode test shall measure hydrocarbon, carbon monoxide, carbon dioxide and oxides of nitrogen emissions, as contained in the bureau's specifications referenced in subsection (a) of Section 3340.17 of this article. The loaded-mode test shall use Acceleration Simulation Mode (ASM) test equipment, including a chassis dynamometer, certified by the bureau.
    On and after March 31, 2010, exhaust emissions from a vehicle subject to this inspection shall be measured and compared to the emissions standards shown in the Vehicle Look-up Table (VLT) Row Specific Emissions Standards (Cutpoints) Table, dated March 2010, which is hereby incorporated by reference. If the emissions standards for a specific vehicle are not included in this table then the exhaust emissions shall be compared to the emissions standards set forth in TABLE I or TABLE II, as applicable. A vehicle passes the loaded-mode test if all of its measured emissions are less than or equal to the applicable emission standards specified in the applicable table.
    (2) A two-speed idle mode test shall be the test method used to inspect 1976 - 1999 model-year vehicles, except diesel-powered, registered in all program areas of the state, except in those areas of the state where the enhanced program has been implemented. The two-speed idle mode test shall measure hydrocarbon, carbon monoxide and carbon dioxide emissions at high RPM and again at idle RPM, as contained in the bureau's specifications referenced in subsection (a) of Section 3340.17 of this article. Exhaust emissions from a vehicle subject to this inspection shall be measured and compared to the emission standards set forth in this section and as shown in TABLE III. A vehicle passes the two-speed idle mode test if all of its measured emissions are less than or equal to the applicable emissions standards specified in Table III.
    (3) An OBD-focused test, shall be the test method used to inspect gasoline-powered vehicles 2000 model-year and newer, and diesel-powered vehicles 1998 model-year and newer. The OBD test failure criteria are specified in section 3340.42.2.
    (b) In addition to subsection (a), all vehicles subject to the smog check program shall receive the following:
    (1) A visual inspection of emission control components and systems to verify the vehicle's emission control systems are properly installed.
    (2) A functional inspection of emission control systems as specified in the Smog Check Manual, referenced by section 3340.45, which may include an OBD test, to verify their proper operation.
    (c) The bureau may require any combination of the inspection methods in sections (a) and (b) under any of the following circumstances:
    (1) Vehicles that the department randomly selects pursuant to Health and Safety Code section 44014.7 as a means of identifying potential operational problems with vehicle OBD systems.
    (2) Vehicles identified by the bureau as being operationally or physically incompatible with inspection equipment.
    (3) Vehicles with OBD systems that have demonstrated operational problems.
    (d) Pursuant to section 39032.5 of the Health and Safety Code, gross polluter standards are as follows:
    (1) A gross polluter means a vehicle with excess hydrocarbon, carbon monoxide, or oxides of nitrogen emissions pursuant to the gross polluter emissions standards included in the tables described in subsection (a), as applicable.
    (2) Vehicles with emission levels exceeding the emission standards for gross polluters during an initial inspection will be considered gross polluters and the provisions pertaining to gross polluting vehicles will apply, including, but not limited to, sections 44014.5, 44015, and 44081 of the Health and Safety Code.
    (3) A gross polluting vehicle shall not be passed or issued a certificate of compliance until the vehicle's emissions are reduced to or below the applicable emissions standards for the vehicle included in the tables described in subsection (a), as applicable. However, the provisions described in section 44017 of the Health and Safety Code may apply.
    (4) This subsection applies in all program areas statewide to vehicles requiring inspection pursuant to sections 44005 and 44011 of the Health and Safety Code.
