Which scan is used to clear the digital footprint or codes recorded during repair?

• A. Pre-repair scan
• B. Mid-repair scan
• C. Post-repair scan
• D. Diagnostic scan

Answer: (C)

After repairs, the post-repair scan is used to verify the fix and clear the fault codes that were stored while the system was malfunctioning. This scan checks that the diagnostic trouble codes are cleared and that the system returns to normal operation, often triggering any needed re-learn or reset steps for components and monitors. It’s the step that confirms the repair actually resolved the issue and that the vehicle isn’t carrying lingering codes that could mislead future diagnostics. A pre-repair scan is done to identify what’s wrong before fixing it, a mid-repair scan isn’t the standard final check, and a diagnostic scan is a broad read of codes and data rather than the focused clearance and validation performed after the repair.
