Post-scans are described as allowing the facility to erase the digital footprint of the repair.

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

Answer: (A)

Post-scans clear diagnostic trouble codes and reset readiness monitors in the vehicle’s control modules. Clearing those codes removes the fault history from the ECU’s memory, which is why it can be described as erasing the digital footprint of the repair. Keep in mind that other records outside the ECU, like service records or shop software logs, may still show that work was performed, so the footprint isn’t erased everywhere.
