(a) The vehicle shall be checked by the vehicle inspector to see that the appropriate fuel cap is securely in place. If the appropriate fuel cap is not in place, it shall result in the failure of the anti-tampering test.

(b) The vehicle shall be checked visually (with a mirror or otherwise) to see if the catalytic converter is the correct type for the certified vehicle configuration and is properly connected. If the catalytic converter has been tampered with, removed or is the incorrect configuration, it shall result in the failure of the anti-tampering test.

(2) Each gasoline powered motor vehicle with a model year of 1996 and newer is subject to an anti-tampering test, and shall comply with the DLC and a fuel cap pressure test. The anti-tampering test shall consist of the following elements:

(a) Vehicle shall be visually checked to see if the appropriate fuel cap is securely in place.

(b) If the fuel cap is present, it shall be removed and a fuel cap pressure test shall be performed to assure the cap is working properly. (F.T.P. 26-21 Pass/Fail Standard). If the fuel cap fails the pressure test, it shall result in a failure of the anti-tampering test.

(c) If the DLC has been tampered with or is missing, it must be repaired or replaced prior to any retesting or reinspection. If the vehicle is incompatible with the OBD test equipment or if the DLC is readily unavailable, then the vehicle is required to pass the idle speed emission values as specified in Paragraph 1200-03-29-.05.

(3) Each diesel powered motor vehicle with a model year of 2002 and newer is subject to an anti-tampering test, and shall comply at a minimum with a DLC check and a fuel cap pressure test. The anti-tampering test shall consist of the following elements:

(a) Vehicle shall be visually checked to see if the appropriate fuel cap is securely in place.

(b) If the DLC has been tampered with or is missing, it must be repaired or replaced prior to any retesting or reinspection. If the vehicle is incompatible with the OBD test equipment or if the DLC is readily unavailable, then the vehicle is subject to the Curb Idle test as specified in Paragraph 1200-03-29-.05.

(4) Pass/fail determination. A pass or fail determination shall be made for each of the test elements in Paragraph 1200-03-29-.08(1), (2), or (3).
