Illinois Statutes Chapter 625. Vehicles § 5/13C-25. Performance of inspections

(a) Except as provided in subsection (b), the inspection of vehicles required under this Chapter shall be performed only: (i) by inspectors who have been certified by the Agency after successfully completing a course of training and successfully passing a written test; (ii) at official inspection stations, including on-road inspection sites established under this Chapter; and (iii) with equipment that has been approved by the Agency for these inspections.

(b) The requirements of subdivisions (a)(i) and (a)(ii) of this Section do not preclude the performance of inspections (1) at self-service official inspection stations, (2) using Agency-approved wireless communication interfaces, and (3) using systems designed to perform remote on-board diagnostic inspections.

(c) Except as provided in subsection (h), the inspection shall consist of an on-board diagnostic system test. The owner of the vehicle or the owner's agent shall be entitled to an emission inspection certificate issued by the Agency only if all required tests are passed at the time of the inspection.

(d) (Blank).

(e) (Blank).

(f) (Blank).

(g) The on-board diagnostic system test shall consist of accessing the vehicle's on-board computer system, determining the vehicle's readiness status and MIL status, and retrieving any stored diagnostic codes that may be present. The vehicle shall be deemed to have passed this test if the vehicle readiness status indicates that the vehicle's OBD system has completed all required system and component checks, the MIL status is appropriate, and the diagnostic codes retrieved do not exceed standards set for vehicles of that type under Section 13C-20.

(h) A visual inspection test of the MIL may be substituted for the on-board diagnostic system test on any vehicle for which on-board diagnostic testing is not possible due to the vehicle's originally certified design or its design as modified in accordance with federal law and regulations, and on any vehicle with known on-board diagnostic communications or software problems, as determined by the Agency. The visual inspection test shall consist of verifying the status of the MIL in the key-on/engine off position and the key-on/engine on position. The vehicle shall be deemed to have passed this test if the MIL illuminates briefly during the key-on/engine off position and does not illuminate during the key-on/engine on position.
