What operation must be performed on a vehicle if it has a sealed emissions control system during inspection?

When inspecting a vehicle with a sealed emissions control system, it is essential to document the seal integrity as part of the inspection process. This involves checking that the seal on the emissions control components is intact and has not been tampered with. Maintaining the integrity of the emissions system is crucial for ensuring that the vehicle complies with environmental regulations and functions effectively in controlling emissions.

By documenting the seal integrity, inspectors provide evidence that the emissions control system is intact, which is necessary for confirming that the vehicle meets the required emissions standards. This step is vital in identifying any potential issues that might affect the performance of the emissions control system without needing to disassemble or replace any components.
