During an inspection, if the air pump has been removed, how should this be noted in the BAR 97 EIS?

When noting the condition of an air pump during a smog check inspection, indicating it as "missing" is the appropriate action if the component has been removed. This designation accurately reflects the absence of the air pump from the vehicle, which is a significant factor in evaluating emissions compliance.

In the context of emissions control, the air pump is typically part of the system designed to inject air into the exhaust stream to help reduce emissions during startup. If this component has been removed, it implies a potential violation of emissions standards, as the vehicle may no longer be functioning as originally designed to control pollutants. Therefore, denoting the air pump as "missing" clearly communicates the status of the emissions control system, allowing for appropriate follow-up actions or penalties according to regulatory standards.

The other options would not accurately describe the situation of an air pump that has been completely removed. For example, labeling it as "replaced" would suggest that the air pump was substituted with a functioning component, and "incomplete" might imply that some components are merely not installed or operational, rather than absent altogether. "Modified" can introduce ambiguity, as it does not specifically address the removal context but rather suggests alteration, which might not capture the absence clearly.
