Cal. Code Regs. tit. 13, § 2176
(b) The inspection shall consist of exhaust emission measurements from the vehicle with the air injection system (if any) connected. Hydrocarbon, carbon monoxide, and oxides of nitrogen concentrations shall be determined by non-dispersive infrared instrumentation.
The cruise mode test shall be performed first on a chassis dynamometer at the speeds and loads shown in the following table:

A vehicle which cannot reach the speed and load specified in the table above, or which by its original design cannot be tested at cruise on an inspection center dynamometer, may be exempted from the cruise mode of the test. Vehicles owned by licensed fleet operators may be exempted from cruise mode test, provided an underhood functional inspection is performed on these vehicles, in addition to idle mode test. An idle mode test may be performed on vehicles at one lane inspection centers wherever dynamometers are inoperative.
The idle mode test shall be performed with the transmission set in neutral gear with the engine at its normal operating temperature. The cruise mode test shall be performed with automatic transmission in drive and with manual transmission set in high gear but overdrive will be disengaged.
(c) In the event of a conflict between the emission standards set forth in subdivision (a) and a manufacturer's specifications for a particular engine family or group of vehicles (defined by make, model year, and emission control system), as demonstrated by an excessive failure rate, by valid assembly-line data of the vehicle manufacturer, or by other data available to the executive officer, the executive officer may by Executive Order exempt such engine families or groups of vehicles from the standards set forth in subdivision (a) and set appropriate separate emission standards.
