静心语录“Deficient Emission Threshold Monitor” means a component/system monitor certified with a deficiency (in accordance with Cal. Code Regs.,
title 13, ction 1971.1(k)) for not detecting a malfunction before
emissions exceeded the malfunction criteria defined in Cal. Code Regs.,
title 13, ctions 1971.1(e) through (g) that are bad on a multiple of, or
an additive to, a tailpipe emission standard or an absolute measurement
from an applicable emission test cycle (e.g., 1.5 times the applicable
Federal Test Procedure (FTP) emission standards, particulate matter (PM) standard plus 0.02 grams per brake horpower-hour (g/bhp-hr), PM level of 0.03 g/bhp-hr as measured from an applicable emission test cycle).

(b) Testing Procedures for ARB-Conducted Testing.
(1) Purpo.
To assure that OBD systems on production engines comply with the
requirements of Cal. Code Regs., title 13, ction 1971.1, ARB may
periodically evaluate engines from an engine class. For OBD systems
that fail to meet requirements of Cal. Code Regs., title 13, ction 1971.1
and for which the noncompliance has been granted a deficiency pursuant to the provisions of Cal. C
ode Regs., title 13, ction 1971.1(k), ARB may evaluate engines with such OBD systems to confirm that the details of the noncompliance are the same as tho disclod by the manufacturer at
the time the deficiency was granted.

(3) Engine Selection for ARB-Conducted Enforcement Testing.
(A) Determining the Engine Class.
* * * *
(iv) Except for testing to determine if an OBD system has been
designed to deactivate bad on age and/or mileage (Cal. Code
Regs., title 13, ction 1971.1(d)(1.3)), the Executive Officer may
not conduct testing of an engine class who engines, on average,
exceed the defined full uful life of the engine class. For purpos
of the determination of this average, the Executive Officer shall u

considering the vehicle weight class, usage type, and other
subcategories as defined and ud by EMFAC2007EMFAC2014,

only engines that:
* * * *
b. Have collected sufficient engine operation data for the monitor to
be tested. For monitors required to meet the in-u monitor
performance ratio and to track and report ratio data pursuant to
Cal. Code Regs., title 13, ction 1971.1(d)(3.2), sufficient
engine operation data shall mean the denominator meets the
criteria t forth in ctions (b)(3)(D)(ii)1. through 5. below. For
monitors required to meet the in-u monitor performance ratio
but not required to track and report ratio data pursuant to Cal.

Cal. Code Regs., title 13, ction 1971.1(d)(4.3), for the monitor
to be tested must have a value equal to or greater than:
* * * *
4. 150 for diel monitors utilizing a denominator incremented in

1971.1(d)(4.3.2)(D), (E), or (F) (e.g., cold start monitors,
comprehensive component output component monitors, etc.)
and not covered in ction (b)(3)(D)(ii)b.3. above, or
5. 300 for all other diel monitors not covered under ctions
(b)(3)(D)(ii)b.3. and 4. above.
* * * *
(iii) In lecting engines to be included in a test sample group for enforcement testing of any other requirement of Cal. Code Regs.,
title 13, ction 1971.1 (not covered by ctions (b)(3)(D)(i) or (ii)
above), the Executive Officer shall include only engines that:

designed to deactivate bad on age and/or mileage (Cal. Code
Regs., title 13, ction 1971.1(d)(1.3)), Hhave mileage and age
that are less than or equal to the certified full uful life mileage
and age for the subject engines.

(4) Enforcement Testing Procedures.
(A) Prior to conducting any testing under ction (b)(4), the Executive
大臀美女Officer may replace components monitored by the OBD system with
components that are sufficiently deteriorated or simulated to cau
微信电脑登陆malfunctions that exceed the malfunction criteria established pursuant
装潢读音to Cal. Code Regs., title 13, ction 1971.1(e) through (g) in a properly operating system. The Executive Officer may not u components
deteriorated or simulated to reprent failure modes that could not
have been foreen to occur by the manufacturer (e.g., the u of
leaded gasoline in an unleaded gasoline engine, etc.). Upon request
by the Executive Officer, the manufacturer shall make available any of the following:
(i) aAll test equipment ud by the manufacturer in development,
calibration, or demonstration testing (e.g., malfunction simulators,
deteriorated “threshold” components, etc.) necessary to duplicate
testing done by the manufacturer to determine the malfunction
criteria ud for major monitors subject to OBD emission testing.
(ii) Complete software design description documentation,
specifications, and source code of the engine control unit and any
other on-board electronic powertrain control unit (e.g., transmission
