Reconnect the battery terminals in the reverse order: positive first, then negative.
Use the Tesla diagnostic tool to scan for airbag-related error codes.
If codes are present, note them down for further investigation.

4. Clear Error Codes

With the diagnostic tool connected, navigate to the airbag system section.
Select the option to clear or reset airbag error codes.
Confirm the action and wait for the tool to complete the process.

5. Verify Reset
