Nintendo Switch Error Code 2002-7001 — What It Means & How to Fix It

What Does This Error Mean?

Error 2002-7001 is a system crash error on Nintendo Switch. It means the console encountered an unexpected problem and was forced to close the software you were running. This can happen with a specific game, system apps, or rarely with the console's operating system itself.

Affected Models

Nintendo Switch
Nintendo Switch Lite
Nintendo Switch OLED

Common Causes

The game or app encountered a software bug that caused it to crash
The microSD card is faulty, too slow, or has corrupted data that the software was trying to read
The game installation has corrupted files that trigger crashes during play
The console's system software is outdated and has a compatibility issue with the game
The Switch is overheating due to a blocked air vent or heavy use in a warm environment

How to Fix It

Restart the Nintendo Switch. Hold the power button for 3 seconds and select Restart from the menu.

A simple restart clears any temporary software glitch that triggered the crash.
Update the game that crashed. From the home screen, highlight the game, press Plus, go to Software Update, and select Via the Internet.

Game updates frequently include crash fixes. Developers patch known issues in updates.
Check the game data for corruption. Go to System Settings > Data Management > Software, highlight the affected game, and select Check for Corrupt Data.

If corruption is found, the Switch will prompt you to delete and redownload the affected files.
Remove the microSD card and test without it. If the game is installed on the card, copy it to the console's internal storage via System Settings > Data Management.

A faulty microSD card is a common cause of random crashes. Testing without the card confirms or rules it out.
Update the system software. Go to System Settings > System > System Update to make sure your Switch is running the latest firmware.

System updates fix compatibility issues and bugs that can cause crash errors like 2002-7001.

Frequently Asked Questions

Did I lose my save data when the error occurred?

Most likely not. Nintendo Switch saves game data separately from the game software. Even if the game crashed, your save file should be intact. However, any progress since your last manual save point may have been lost, as the game could not auto-save during a crash.

Why does error 2002-7001 only happen in one specific game?

If only one game is affected, the issue is almost certainly specific to that game's software. Try updating the game first. If updates are available, they often include crash fixes. If the game is up to date and still crashes, try deleting and redownloading it.

Can heat cause this error?

Yes. The Nintendo Switch can overheat if the air vents on the back of the console are blocked. Always place the Switch on a hard, flat surface when in TV mode — not on a bed or carpet that can block the vents. In handheld mode, avoid blocking the air vents on the top of the console.
