Check the airbag system fuse based on the vehicle's manual.
Replace any blown fuses with the correct amperage.

3. Check and Clean Connectors

Tools Required: Electrical contact cleaner, small brush.
Slide the front seats forward to access connectors beneath them.
Disconnect the connectors and inspect for corrosion or damage.
Clean any corrosion using the electrical contact cleaner and a small brush, then reconnect.

4. Replace Faulty Components

If diagnostic codes indicate a specific component failure (e.g., airbag module, seat sensor), follow these steps:
- Tools Required: Socket set, torque wrench.
- Remove any trim or covers to access the component.
- Disconnect wiring harnesses and remove the component.
- Install the new component, ensuring all connections are secure.
- Reinstall any trim or covers removed.
