ENGINES (CONTINUED)--Table of Contents
 
  Subpart G--Selective Enforcement Auditing of New Light-Duty Vehicles
 
Sec. 86.608-96  Test procedures.

    Section 86.608-96 includes text that specifies requirements that 
differ from Sec. 86.608-90. Where a paragraph in Sec. 86.608-90 is 
identical and applicable to Sec. 86.608-96, this is indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec. 86.608-90.'' Where a corresponding paragraph of 
Sec. 86.608-90 is not applicable, this is indicated by the statement 
``[Reserved].''
    (a) The prescribed test procedures are the FTP as described in 
subpart B of this part, the cold temperature CO test procedure as 
described in subpart C of this part, and the CST as described in subpart 
O of this part, as applicable. For purposes of Selective Enforcement 
Audit testing, the manufacturer may not perform any of the test 
procedures in subpart B of this part relating to evaporative emission 
testing, except as specified in Sec. 86.608-90(a)(2).
    (1) The Administrator may select and prescribe the sequence of any 
CSTs. Further, the Administrator may, on the basis of a written 
application by a manufacturer, approve optional test procedures other 
than those in subparts B, C, and O of this part for any motor vehicle 
which is not subject to satisfactory testing using the procedures in 
subparts B, C, and O of this part.
    (2) through (3) [Reserved]. For guidance see Sec. 86.608-90.
    (4) The exceptions to the test procedures described in subpart O of 
this part that are listed in paragraphs (a)(4)(i) and (ii) of this 
section are applicable to Selective Enforcement Audit testing.
    (i) The manufacturer need not comply with Sec. 86.1442, since the 
records required therein are provided under other provisions of subpart 
G of this part.
    (ii) In addition to the requirements of subpart O of this part, the 
manufacturer must prepare vehicles as in paragraphs (a)(4)(ii) (A) 
through (C) of this section prior to exhaust emission testing.
    (A) The manufacturer must inspect the fuel system to insure the 
absence of any leaks of liquid or vapor to the atmosphere by applying a 
pressure of 14.5 0.5 inches of water to the fuel system, 
allowing the pressure to stabilize, and isolating the fuel system from 
the pressure source. Pressure must not drop more than 2.0 inches of 
water in five minutes. If required, the manufacturer performs corrective 
action in accordance with this section and must report this action in 
accordance with Sec. 86.609.
    (B) When performing this pressure check, the manufacturer must 
exercise care to neither purge nor load the evaporative system.
    (C) The manufacturer may not modify the test vehicle's evaporative 
emission control system by component addition, deletion, or 
substitution.
    (b) through (i) [Reserved]. For guidance see Sec. 86.608-90.
