Which of the following vehicle makers have released a position statement for pre- and post-repair scan requirements?

• A. Toyota
• B. All of the Above
• C. Honda
• D. Ford

Answer: (B)

Pre- and post-repair scanning is about using a diagnostic tool to capture the vehicle’s current fault data before work starts and to verify the repair after work is finished. This practice helps ensure nothing was missed and that all systems communicate correctly after work, which supports safety, proper function, and warranty considerations. All three makers have published position statements requiring or endorsing this approach, showing a consistent expectation across major brands. A pre-scan collects existing trouble codes, freeze-frame data, and system readiness status to guide the repair plan. After the repair, a post-scan checks that the faults are resolved, that no new codes appeared, and that any necessary re-learns, calibrations, or module resets are completed. Because each of these makers advocates for both scans as part of a responsible repair process, the correct choice is that all of the above.
