One advantage of performing a pre-scan is that it can identify whether damage is related or unrelated to the collision.

• A. True
• B. False
• C. Not stated
• D. Not relevant

Answer: (A)

A pre-scan provides a snapshot of the vehicle’s electronic systems before any repairs, so you can see what faults exist and what fault codes were present prior to the collision. This lets you determine which issues are related to the crash and which were pre-existing or unrelated. By reading memory from essential modules—airbags, ABS, engine, transmission, steering, etc.—you can identify, for example, a pre-existing fault that wasn’t caused by the crash, or a new fault that appears only after the incident. That clarity helps you plan the correct repairs, address safety-critical systems appropriately, and avoid misattributing pre-existing problems to the collision. So the statement is true: a pre-scan can identify whether damage is related or unrelated to the collision.
