why is my Tesla Model S Plaid/Refresh (2021-present) airbag light on how to fix

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, multimeter, and safety glasses.
• Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Retrieve Error Codes

• Connect the OBD-II scanner to the vehicle's diagnostic port.
• Turn on the ignition without starting the vehicle.
• Follow the scanner's instructions to retrieve and record any error codes related to the airbag system.

3. Inspect Wiring and Connectors

• Safely disconnect the vehicle's battery (disconnect negative terminal first).
• Remove any necessary panels to access airbag wiring and connectors.
• Visually inspect all wiring for signs of wear, corrosion, or damage.
• Reconnect any loose connectors and repair or replace damaged wiring as necessary.

4. Check Airbag Modules

• Inspect the locations of airbag modules (steering wheel, dashboard, side curtains) for proper installation.
• Use a multimeter to test the resistance of the airbag circuits to ensure they are within specifications.
• Replace any faulty airbag modules as indicated by diagnostic results.

5. Reset Airbag System

• Reconnect the vehicle's battery (connect positive terminal first, then negative).
• Use the OBD-II scanner to clear any stored error codes.
• Turn on the ignition and verify that the airbag warning light is no longer illuminated.
