Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, ratchet, safety gloves.
Ensure the vehicle is parked on a level surface, and the ignition is off. Disconnect the negative terminal of the battery.

2. Check for DTCs

Connect the OBD-II scanner to the diagnostic port located under the steering column.
Turn the ignition to the "On" position without starting the engine.
Navigate the scanner to read the airbag system codes. Note any specific codes that are displayed.

3. Clear DTCs

With the scanner still connected, select the option to clear or erase DTCs.
Confirm the action and wait for the scanner to complete the process.
Disconnect the scanner after clearing the codes.

4. Reconnect Battery

Reconnect the negative battery terminal and ensure it is tight.
Allow the system to reset by waiting a few moments before starting the vehicle.

5. Test the System

Start the engine and check if the airbag light remains illuminated.
If the light goes off, the reset was successful. If it stays on, further diagnosis may be required.
