Hand over your test history
What they doWhen booking the repair, give the code, whether it appeared at power on or on waking, and the result without a card and with other cards.
They must show youunder which condition they reproduced the error in their tests.
In writingThe intake date, the recorded code and the tests done before opening the console.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
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.
Restart or force a shutdown
- Who:
- you.
- How:
- Hold POWER for three seconds and choose Power Options > Restart. If the console does not respond, hold POWER for twelve seconds to force it off, then turn it back on.
- Result that matters:
- Whether 2002-3005 shows again at power on or when waking from sleep.
- If it does not:
- install the latest system update and keep using the console, watching for a repeat.
- If it shows again:
- move on to starting without the card.
- Evidence to keep:
- A photo of the code, whether it came at power on or on waking, and whether it returned after the restart.

Start without the microSD Express or microSD card
- Who:
- you.
- How:
- Power the console off, take out the microSD Express card (Switch 2) or microSD card (Switch) and turn it on again.
- Result that matters:
- Whether the error appears with the slot empty.
- If it does not:
- the problem is tied to the card; update the console and go on to format or replace it.
- If it appears with no card:
- Nintendo says the console needs repair.
- Evidence to keep:
- Card brand and capacity, and the start-up result with and without it.

Format the card or try another one
- Who:
- you, after copying any screenshots stored on the card to your computer.
- How:
- Format the card from the console or use a different compatible card.
- Result that matters:
- Whether the console starts without 2002-3005 using the formatted card or the new one.
- If it starts normally:
- the card or its data was the source; digital software can be downloaded again with the Nintendo Account that bought it.
- If it fails with several cards:
- note which ones you tried for the service centre.
- Evidence to keep:
- The screenshot backup made before formatting and the list of cards tried.
Formatting erases the card and Nintendo says the data cannot be recovered. Back up the screenshots first.

What it means
Nintendo documents 2002-3005 on Nintendo Switch 2 and Nintendo Switch when it appears while the console powers on or wakes from sleep mode. Its steps split two paths: a one-off fault that clears with a restart and a system update, and a fault tied to the microSD Express card (Switch 2) or microSD card (Switch), which shows up when the console starts without it. Only if the error persists at start-up with no card inserted does Nintendo send the console to repair. The code does not identify a failed part.
