Section 44012 Of Article 2. Program Requirements From California Health And Safety Code >> Division 26. >> Part 5. >> Chapter 5. >> Article 2.
44012
. The test at the smog check stations shall be performed in
accordance with procedures prescribed by the department and may
require loaded mode dynamometer testing in enhanced areas, two-speed
idle testing, testing utilizing a vehicle's onboard diagnostic
system, or other appropriate test procedures as determined by the
department in consultation with the state board. The department shall
implement testing using onboard diagnostic systems, in lieu of
loaded mode dynamometer or two-speed idle testing, on model year 2000
and newer vehicles only, beginning no earlier than January 1, 2013.
However, the department, in consultation with the state board, may
prescribe alternative test procedures that include loaded mode
dynamometer or two-speed idle testing for vehicles with onboard
diagnostic systems that the department and the state board determine
exhibit operational problems. The department shall ensure, as
appropriate to the test method, the following:
(a) Emission control systems required by state and federal law are
reducing excess emissions in accordance with the standards adopted
pursuant to subdivisions (a) and (c) of Section 44013.
(b) Motor vehicles are preconditioned to ensure representative and
stabilized operation of the vehicle's emission control system.
(c) For other than diesel-powered vehicles, the vehicle's exhaust
emissions of hydrocarbons, carbon monoxide, carbon dioxide, and
oxides of nitrogen in an idle mode or loaded mode are tested in
accordance with procedures prescribed by the department. In
determining how loaded mode and evaporative emissions testing shall
be conducted, the department shall ensure that the emission reduction
targets for the enhanced program are met.
(d) For other than diesel-powered vehicles, the vehicle's fuel
evaporative system and crankcase ventilation system are tested to
reduce any nonexhaust sources of volatile organic compound emissions,
in accordance with procedures prescribed by the department.
(e) For diesel-powered vehicles, a visual inspection is made of
emission control devices and the vehicle's exhaust emissions are
tested in accordance with procedures prescribed by the department,
that may include, but are not limited to, onboard diagnostic testing.
The test may include testing of emissions of any or all of the
pollutants specified in subdivision (c) and, upon the adoption of
applicable standards, measurement of emissions of smoke or
particulates, or both.
(f) A visual or functional check is made of emission control
devices specified by the department, including the catalytic
converter in those instances in which the department determines it to
be necessary to meet the findings of Section 44001. The visual or
functional check shall be performed in accordance with procedures
prescribed by the department.
(g) A determination as to whether the motor vehicle complies with
the emission standards for that vehicle's class and model-year as
prescribed by the department.
(h) An analysis of pass and fail rates of vehicles subject to an
onboard diagnostic test and a tailpipe test to assess whether any
vehicles passing their onboard diagnostic test have, or would have,
failed a tailpipe test, and whether any vehicles failing their
onboard diagnostic test have or would have passed a tailpipe test.
(i) The test procedures may authorize smog check stations to
refuse the testing of a vehicle that would be unsafe to test, or that
cannot physically be inspected, as specified by the department by
regulation. The refusal to test a vehicle for those reasons shall not
excuse or exempt the vehicle from compliance with all applicable
requirements of this chapter.
