Solution

1. Preparation

Tools Required: Tesla diagnostic tool, basic hand tools (screwdrivers, socket set), multimeter.
Ensure the vehicle is parked on a level surface, and the ignition is in the OFF position.
Disconnect the 12V battery for safety (negative terminal first).

2. Clear Fault Codes

Connect the Tesla diagnostic tool to the vehicle's OBD-II port.
Navigate to the airbag module section in the diagnostic software.
Select the option to read and clear fault codes.
Confirm the deletion of any stored airbag fault codes.

3. Inspect Components

Reconnect the vehicle's battery (positive terminal first).
Inspect the airbag connectors under the front seats and dashboard for any loose or corroded connections.
Use a multimeter to test the continuity of the airbag circuit if necessary.
Ensure that all seatbelt sensors are functioning correctly.

4. Test Airbag System

With the vehicle in the ON position (do not start), observe the airbag warning light.
If the light remains off after clearing codes and checking connections, conduct a system test using the diagnostic tool.

5. Reassemble and Finalize

If no issues are found, reassemble any components that were removed for access.
Reconnect the battery and ensure all tools are cleared from the vehicle.
Perform a final check of the airbag warning light status.
