Sec. 9. (a) Each motor vehicle subject to the requirements of this rule shall be subjected to a visual tampering inspection at the facility. The motor vehicle shall be inspected for the presence and good operating condition of emission control devices included in the manufacturer's original design. At a minimum, emission control devices subject to inspection shall include the following:

1. (1) For I/M 93 emission testing:

   1. (A) Catalytic converters.
   2. (B) Fuel filler caps.

2. (2) For basic I/M emissions testing:

   1. (A) Catalytic converters.
   2. (B) Fuel filler caps.

If any emission control devices are found in a tampered condition, the devices shall be repaired or replaced prior to any initial testing, retesting, or reinspection as provided in section 8(f) of this rule.

(b) Alteration of a vehicle's chassis configuration from a certified to a noncertified configuration is prohibited. In the inspection process, vehicles that have been altered from their original, certified configuration are to be tested in the same manner as other subject vehicles as follows:

1. (1) Vehicles with engines other than the engine originally installed by the manufacturer or an identical replacement of the engine shall be subject to the inspection standards for the chassis type and model year for all parts that are part of the original or now-applicable certified configuration.

2. (2) Vehicles in which the engine of one (1) fuel type has been replaced or modified to an engine of a different fuel type that is subject to the I/M program, such as from a diesel engine to a gasoline engine, shall be subject to the following:

   1. (A) The test procedures and standards for the current fuel type.
   2. (B) The requirements in subdivision (1).
3. (3) Vehicles that are switched to a fuel type for which there is no certified configuration shall be tested according to the most stringent I/M gasoline emission standards established for that vehicle type and model year. Emission control device requirements may be waived if the department determines that the alternatively fueled vehicle configuration would meet the new vehicle standards for the model year without the devices.

(c) Mixing vehicle classes, such as light-duty with heavy-duty, and certification types, such as California with federal, within a single vehicle configuration shall be considered tampering.

(d) All vehicles must comply with 326 IAC 13-2.1.
