Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers), torque wrench.
Ensure the vehicle is turned off and parked on a level surface with the ignition key removed.

2. Scan for DTCs

Connect the OBD-II scanner to the diagnostic port under the dashboard.
Turn the ignition key to the "On" position (do not start the engine).
Read the diagnostic trouble codes and record any relevant codes that pertain to the airbag system.

3. Inspect the Wiring and Connectors

Disconnect the battery by removing the negative terminal to prevent accidental airbag deployment.
Visually inspect the airbag system wiring harness and connectors for any signs of fraying, corrosion, or disconnection.
If any issues are found, repair or replace the affected wiring or connectors as necessary.

4. Check and Replace the SRS Fuse

Locate the fuse box, typically found under the dash or in the engine compartment.
Identify the SRS fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with one of the same amperage rating.

5. Verify Seatbelt Sensors

Inspect the seatbelt buckle and retractor for proper function.
Check for any obstructions or damages that may prevent the sensors from working correctly.
Replace any faulty seatbelt components if needed.

6. Reset the Airbag System

After addressing all identified issues, reconnect the battery.
Use the OBD-II scanner to clear any DTCs and perform a system reset.
Turn the ignition key to the "On" position and check if the airbag light remains off.
