When documenting a missing ECS during a Smog Check, which entry is correct?

• A. Leave ECS status blank
• B. Mark ECS as present on the log
• C. Note ECS as not applicable in the report
• D. List the system as Missing in the EIS machine

Answer: (D)

Documenting the Evaporative Control System status clearly in the official data entry is essential. The Emission Inspection System (EIS) is the formal record of a smog check, and it requires an explicit status for each emission subsystem. When the evaporative control system is missing, you must record that status as Missing in the EIS. This provides an accurate, auditable log of the vehicle’s condition and ensures the test result isn’t misinterpreted as having been completed with a functioning ECS. Leaving the field blank, marking it as present, or calling it not applicable would misrepresent the situation or mislead the report. Recording it as Missing in the EIS machine communicates the true condition and guides any required follow-up or repairs.
