(a) Heavy-duty diesel-powered vehicles. No heavy-duty diesel-powered vehicle shall operate in California with tampered, inadequately maintained, or defective emission control components. The CARB shall conduct a visual inspection of heavy-duty diesel-powered vehicles to determine whether emission control components have been tampered with, inadequately maintained, or are defective. The inspection shall include, but is not limited to, the following:

(1) The engine governor.

(2) Any seals or covers protecting the air-fuel ratio adjustments.

(3) Any fuel injection pump seals and covers.

(4) The air cleaner and flow restriction indicator.

(5) The exhaust gas recirculation valve.

(6) The particulate matter trap system or catalytic converter system, including all related sensors, actuators, and monitors.

(7) Related hoses, connectors, brackets, and hardware for these components.

(8) Engine computer controls, related sensors, and actuators.

(9) Emission control label (ECL).

(10) Any other emissions-related components for a particular vehicle/engine as determined from the manufacturer's specifications, emission control label, certification data, or published vehicle parts manuals.

(11) An interrogation or visual inspection of a malfunction indicator light (MIL) of the on-board diagnostics (OBD) system, engine manufacturer diagnostic system (EMD), or emission control module (ECM) system, where applicable.

(b) Heavy-duty gasoline-powered vehicles. No heavy-duty gasoline-powered vehicle shall operate in California with tampered or defective emission control components. The CARB shall conduct a visual inspection of heavy-duty gasoline-powered vehicles to determine whether emission control components have been tampered with or are defective. The inspection shall include, but is not limited to, the following:

(1) The air injection system.

(2) The positive crankcase ventilation system.

(3) The exhaust gas recirculation system.

(4) The catalytic converter, including pipes and valves.

(5) The evaporative emission control system.

(6) Related hoses, connectors, brackets, and hardware for these components.

(7) Engine computer controls, related sensors, and actuators.

(8) On-Board Diagnostic (OBD) systems for 1994 and subsequent model year vehicles, if so equipped.

(9) Emission control label (ECL).

(10) Any other emissions-related component for a particular vehicle/engine as determined from the manufacturer's specifications, emission control label, certification data, or published vehicle parts manuals.

(11) An interrogation or visual inspection of a malfunction indicator light (MIL) of the on-board diagnostics (OBD) system.

(c) No 1974 or newer diesel powered heavy-duty commercial vehicle shall operate in California without evidence that, at the time of manufacture, the installed engine met emission standards at least as stringent as applicable federal emission standards for the model year of the engine. The CARB shall base its determination on whether an engine meets the above requirements by inspecting the emission control label (ECL) affixed to the vehicle's engine.
