Scan Tool
On OBDII systems, is it possible (with a scan tool) to read a car’s code history and/or recent resets?
This would be a valuable resource for evaluating a used car, pre-purchase.
The only way you can read the car’s history is if it has not been cleared. Once the codes are cleared they are gone unless the problem comes back. If you are looking into a used car and are worried that they just cleared the codes ask them to let you drive it for a few days. Any problems the car has will pop back after 3 drive cycles (car heating up to operating temp). If nothing pops back it won’t matter about previous problems because they would have to be fixed or the code would come back.
