Remove the airbag fuse and inspect it visually for continuity.
Replace with a new fuse of the same amperage if blown.

4. Check Connections and Wiring

Remove the steering wheel cover and inspect the airbag connector for secure attachment and damage.
Inspect wiring harnesses for frays, corrosion, or disconnections.
Repair or replace any damaged wiring as needed.

5. Testing Components

Test the seatbelt tensioners using a multimeter to ensure they are functioning correctly.
If necessary, replace faulty components, including airbag modules or sensors.
