- If the error goes away:
- no need to go further.

Check card compatibility and capacity
- Who:
- you, with the card and its label or packaging.
- How:
- confirm the card is compatible with your console (on Switch 2, microSD Express). Compare the capacity on the label or packaging with the total capacity the console shows.
- Result that matters:
- knowing whether the card is suitable and has the capacity it claims.
- If the gap is more than 1 GB:
- Nintendo asks you to contact the card's retailer.

- go on to format it or try another.
- Evidence to keep:
- photo of the label and of the capacity shown by the console.

Format, try another card and reseat powered off
- Who:
- you, after backing up screenshots and videos to a computer.

- Result that matters:
- knowing whether the error follows the card.
- If it stops appearing:
- the problem was the card, its data or the contact.
- If it still appears:
- delete the game and redownload it to system memory.
- Evidence to keep:
- which cards you tried and what happened with each.
Formatting erases the whole card; back up screenshots and videos first.

- If it works:
- the fault was tied to the card or the game data on it.
- If the error continues:
- Nintendo says the console needs repair.
- Evidence to keep:
- result of the game from system memory and the date.

What it means
Nintendo gives two paths for 2002-4802 on Nintendo Switch 2 and Nintendo Switch: with a microSD or microSD Express card, and without one. Both start with the latest system version and a corrupted data check. With a card it adds compatibility, real capacity, formatting, another card, reseating with the console off and redownloading the game to system memory. The code does not prove on its own that the card or the console is faulty; repair only comes if the error persists after those steps.
