Section 86.131-00 includes text that specifies requirements that differ from §86.131-96. Where a paragraph in §86.131-96 is identical and applicable to §86.131-00, this may be indicated by specifying the corresponding paragraph and the statement “[Reserved]. For guidance see §86.131-96.”
(a)-(e) [Reserved]. For guidance see §86.131-96.
(f) For vehicles to be tested for aggressive driving emissions (US06), provide a throttle position sensing signal that is compatible with the test dynamometer. This signal provides the input information that controls dynamometer dynamic inertia weight adjustments (see §§86.108-00(b)(2)(ii) and 86.129-00(f)(2)). If a manufacturer chooses not to implement dynamic inertia adjustments for a portion or all of their product line, this requirement is not applicable.
(g) You may disable any AECDs that have been approved solely for emergency vehicle applications under paragraph (4) of the definition of defeat device. The emission standards do not apply when any of these AECDs are active.
