Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and allow it to sit for at least 10 minutes to prevent accidental airbag deployment.
Ensure the work area is safe and well-lit.

2. Scan and Record Error Codes

Use the OBD-II scanner to retrieve and record any error codes related to the airbag system.
Document the codes for reference during repairs.

3. Inspect Wiring and Connectors

Visual inspection: Check all wiring and connectors associated with the airbag system for fraying or damage.
If damaged, replace the wiring or connectors as needed.

4. Check Airbag Module and Sensors

Locate the airbag control module (usually under the center console or dashboard).
Inspect for any signs of physical damage or corrosion.
Test the crash sensors' continuity using a multimeter; replace if faulty.

5. Test Seatbelt Switches

Unplug the seatbelt buckle switch connectors and check for proper continuity.
If the switch is defective, replace it with a new one.

6. Clear Codes and Reconnect Battery

After repairs, use the OBD-II scanner to clear any stored airbag error codes.
Reconnect the vehicle battery, ensuring all connections are secure.
