Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Update and check the software
- Who:
- you.
- How:
- Install the latest system update, run the corrupt data check and delete and redownload the software showing the error.
- Result that matters:
- Whether the card access message returns.
- If it does not:
- the problem was the software's data.
- If it does:
- move on to the card.
- Evidence to keep:
- The system version, the affected software and the check result.

Check card compatibility and capacity
- Who:
- you.
- How:
- Check the card type: Switch 2 only accepts microSD Express (up to 2 TB); Switch accepts microSD (up to 2 GB), microSDHC (4 to 32 GB) and microSDXC (64 GB to 2 TB). Compare the label capacity with the one the console shows.
- Result that matters:
- That the card is a supported type and the capacity difference is no more than 1 GB.
- If it is not compatible:
- replace it with a compatible one.
- If the difference exceeds 1 GB:
- Nintendo says to contact the retailer.
- Evidence to keep:
- A photo of the label and of the capacity the console shows.

Reinsert, format or download to system memory
- Who:
- you, copying screenshots to your computer first if you will format.
- How:
- With the console off, remove the card and insert it again. If it persists, format it, try another card or download the software to system memory.
- Result that matters:
- With which storage the error disappears.
- If it disappears with another card or in memory:
- the original card was the source.
- If it fails with several compatible cards and in memory:
- Nintendo says the console needs repair.
- Evidence to keep:
- The result of each test and the cards used.
Remove or insert the card only with the console off, as the message itself says. Formatting erases the contents.

What it means
Nintendo shows 2002-2046 with the message that the microSD card could not be accessed. Its steps start with software (update, corrupt data, redownload) and then move to the card: compatibility (Switch 2 microSD Express up to 2 TB only; Switch microSD, microSDHC and microSDXC), real capacity against the label, reinsertion with the console off, formatting, another card or download to system memory. If it fails with several cards or with no card, repair follows. The message does not prove the card is broken.
