    Section 86.000-16 includes text that specifies requirements that 
differ from Sec. 86.094-16. Where a paragraph in Sec. 86.094-16 is 
identical and applicable to Sec. 86.000-16, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec. 86.094-16.''
    (a) No new light-duty vehicle, light-duty truck, heavy-duty vehicle, 
or heavy-duty engine shall be equipped with a defeat device.
    (b) The Administrator may test or require testing on any vehicle or 
engine at a designated location, using driving cycles and conditions 
which may reasonably be expected to be encountered in normal operation 
and use, for the purpose of investigating a potential defeat device.
    (c) [Reserved]. For guidance see Sec. 86.094-16.
    (d) For vehicle and engine designs designated by the Administrator 
to be investigated for possible defeat devices:
    (1) The manufacturer must show to the satisfaction of the 
Administrator that the vehicle or engine design does not incorporate 
strategies that unnecessarily reduce emission control effectiveness 
exhibited during the Federal emissions test procedure when the vehicle 
or engine is operated under conditions which may reasonably be expected 
to be encountered in normal operation and use.
    (d)(2) through (d)(2)(ii) [Reserved]. For guidance see Sec. 86.094-
16.
