Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to avoid accidental airbag deployment.
Wait at least 10 minutes to allow the system to discharge.

2. Address Error Codes

Sub-step 1: Reconnect the OBD-II scanner and retrieve any stored airbag-related error codes.
Sub-step 2: Research the error codes using a repair manual or online database for specific troubleshooting steps.
Sub-step 3: Address any identified issues (e.g., repair broken connections or replace faulty sensors).

3. Reset Airbag Light

Sub-step 1: With the vehicle still off, reconnect the negative battery terminal.
Sub-step 2: Turn the ignition to the "ON" position (do not start the engine) and leave it for about 10 seconds to allow the system to reset.
Sub-step 3: If the airbag light remains on, use the OBD-II scanner to clear the codes, which should reset the light.

4. Final Check

Sub-step 1: Start the vehicle and observe if the airbag light remains off.
Sub-step 2: Conduct a test drive to ensure the airbag system operates correctly without triggering the light.
