SUBPART H: ON-BOARD DIAGNOSTIC TEST STANDARDS
Section 240.191 Applicability
The standards of this Subpart apply to all 1996 and newer model year light duty vehicles, light
duty trucks 1, and light duty trucks 2 that are required to meet the standards contained in 40 CFR
§ 86.094-17 and which are inspected utilizing the on-board diagnostic test procedures contained
in 35 Ill. Adm. Code 276.209. Vehicles that receive a result of fail do not thereby fail their
emissions test until January 1, 2002. However, this date shall be extended to January 1, 2003, if
the Agency petitions the USEPA for such an extension, and the request for an extension is
approved by the USEPA pursuant to 40 CFR § 51.357(a)(12).
