An active fault generally means the controller currently recognizes the conditions required to report that fault. A stored or inactive fault records a condition that was detected previously and is not currently reported in the same way. The exact terminology and available status information depend on the system and diagnostic application.
Neither status provides a complete repair decision on its own. An active code does not prove that the named component must be replaced, and an inactive code is not automatically irrelevant. Intermittent complaints may leave useful history even when the vehicle behaves normally during the workshop visit. Compare the scan with the customer's description and recent service work.
Save the complete initial report before clearing anything. Include the reporting controller, full fault identifier, status and any available occurrence or event information. Where the tool provides it, related operating data can help show the conditions around a fault. The usefulness of those records depends on what the controller actually stores, so avoid promising the same history on every vehicle.
Use service information to understand the detection and clearing conditions. A fault may become inactive because the relevant check is no longer failing or because the conditions for that check have changed. Emissions-related systems may also use pending, confirmed or permanent statuses with different rules. Do not apply one controller's interpretation to every entry in a mixed vehicle scan.
Investigate the confirmed concern, complete the repair and verify it under the specified conditions. Save the final report and explain remaining historical information rather than erasing it without context. A clear record shows what the workshop found and tested. It is more useful than a fault list with no history and no evidence that the customer's symptom has been resolved.
