Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdriver, safety glasses
Disconnect the vehicle's negative battery terminal to prevent accidental airbag deployment while working on the system.
Allow the vehicle to sit for at least 10 minutes after disconnecting the battery.

2. Inspect Wiring and Connectors

Remove the appropriate trim panels to access airbag wiring harnesses.
Check for any loose, frayed, or damaged wires in the airbag system.
Ensure all connectors are seated properly and free of corrosion.
Use a multimeter to test the continuity of wires and connections.

3. Check Seatbelt Sensors

Inspect the seatbelt sensors for proper installation and functionality.
Disconnect and reconnect the seatbelt connectors to ensure a good connection.
Replace any faulty seatbelt sensors if necessary.

4. Battery Voltage Check

Use a multimeter to measure the vehicle's battery voltage.
Ensure the voltage is above 12.4 volts; if not, charge or replace the battery as needed.
