If a DTC was set 35 miles before the customer dropped off the vehicle, there is a good chance it could be collision related.

• A. 5 miles
• B. 15 miles
• C. 35 miles
• D. 60 miles

Answer: (C)

Understanding how far back in the trip the DTC was set helps judge how recent the fault is and whether a crash could be involved. If the DTC was recorded about 35 miles before the vehicle was dropped off, that places the fault during the last leg of the drive and makes a collision during that trip a plausible source. After a collision, related faults often appear and can linger as the vehicle is driven, so this 35-mile window fits a collision-related explanation. Shorter distances (like 5 or 15 miles) point to events that are even closer to the check-in moment, while a longer span (such as 60 miles) weakens the direct link to the crash because more driving events could cause other faults. So 35 miles is a reasonable middle-ground indication that a collision could be involved.
