2022 Lexus GX — check-engine light turned itself off — still scan it?

The light was on for two days and then disappeared before I could schedule service. Car feels normal. Is there still likely to be useful stored or pending data if I scan it now?

Ask what changed right before it started. A pressure test beats staring at a dry driveway if the 2022 Lexus GX is losing coolant with no puddle. Save the big job until that test fails. Run the total, not the monthly, before you commit. I'd rather look cautious in this thread than stuck later.

Quick add on that: Capture voltage while the 2022 Lexus GX is actually failing — after it restarts you've lost the clue. If the cheap test changes it, stop and reassess. I'd want a dollar figure or a measured spec, not 'should be fine.' Next check is the cheap one I can do in a driveway.

I'd push back a little: A pressure test beats staring at a dry driveway if the 2022 Lexus GX is losing coolant with no puddle. That's the branch I'd chase this week. This is from a 2022 Lexus GX in Florida. Run the total, not the monthly, before you commit. If the story changes I'll post the new data.
