The Check Engine light has come up on my mom's '99 S80.

Assuming I can find a parts store that has a scan tool, what is the procedure?

Engine OFF
key to RUN (but not started)
Scan tool PLUGGED IN
Read codes?

I've checked the gas cap and it is properly attached and sealing surfaces appear clean and undamaged.

Car has 75k miles; she is original/only owner. She hasn't driven for a year or so; I drive the car when I do her shopping every week so it gets driven, but not much.

I gassed up the car and took it on a 200 mile trip to give it some exercise. I noticed the CEL after about 30 min. Drive ability is fine - no issues.

Car has been well-maintained by local indie shop,

Any thoughts appreciated. If I can save her the expense of a shop visit to resolve a simple issue it would be helpful.
