(c) A diesel bus, tested using the snap acceleration smoke opacity test at 7:27B-4.3, shall not emit smoke in the exhaust emissions that exceeds the following opacity standards:

1. For model years 1987 and older, the level of peak smoke opacity shall not exceed 40 percent;

2. For model years 1988 through 1993, the level of peak smoke opacity shall not exceed 30 percent; and

3. For model years 1994 and newer, the level of peak smoke opacity shall not exceed 20 percent.

(d) A retrofitted diesel bus, tested using the snap acceleration smoke opacity test at 7:27B-4.3, shall not emit smoke in the exhaust emissions that exceeds the following opacity standards:

1. For model years 1993 and older, the level of peak smoke opacity shall not exceed 30 percent;

2. For model years 1994 and newer, the level of peak smoke opacity shall not exceed 20 percent.

(e) A motor vehicle or motor vehicle engine with a certified configuration in which any element of design installed on such vehicle has been disconnected, detached, deactivated, or in any other way altered or modified from the design of the original vehicle manufacturer, in a manner not in accordance with EPA Memorandum 1A or not exempt from prohibition by CARB Executive Order, will be deemed to have failed the motor vehicle inspection.

1. The DLC cannot be found or is damaged/obstructed in such a way as to not allow a connection between the analyzer and the motor vehicle;

2. Communication cannot be established between the analyzer and the vehicle's OBD system;

3. The MIL is not illuminating when commanded to light;

4. The number of systems that have non-continuous readiness monitors that are not ready for inspections equals or exceeds the following criteria: three "not ready" codes for motor vehicles model year 1997 through 2000 and two "not ready" codes for motor vehicles model year 2001 and newer;

5. Any continuous readiness monitor is not supported or not ready;
