In the automotive industry context, “pre-scan” and “post-scan” typically refer to diagnostic scans performed on a vehicle’s onboard computer systems before and after repairs or maintenance.
A “pre-scan” is done before any work on the vehicle to identify existing issues and ensure all systems are functioning properly. It helps mechanics pinpoint problems that might not be immediately apparent.
After the repairs or maintenance, a “post-scan” is conducted to verify that all systems are working correctly and that any diagnostic trouble codes have been cleared. It ensures the vehicle is in the same or better condition than before the work was done.
These scans are essential for ensuring the safety and performance of modern vehicles, which rely on complex computer systems for various functions.
