Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery cable and wait at least 10 minutes to ensure the airbag system is deactivated.
Tools required: OBD-II scanner, socket set, multimeter, electrical contact cleaner.

2. Inspect and Replace Fuses

Locate the fuse box; typically under the dashboard or in the engine compartment.
Use the fuse diagram to identify the airbag fuse.
Remove the fuse and inspect it visually; replace it if blown with a new fuse of the same amperage.

3. Repair or Replace Faulty Connections

Inspect the seat belt connections and pretensioners.
If any connections are damaged, repair or replace the connector or wiring.
Ensure all connections are secure and free from corrosion.

4. Test Airbag Sensors

Use a multimeter to test the resistance of each airbag sensor.
If any sensor is out of specification, replace it with a new sensor.
Ensure wiring to each sensor is intact and properly connected.

5. Reset the Airbag System

Reconnect the negative battery cable.
Use the OBD-II scanner to clear any stored codes from the airbag system.
Verify that the airbag light has turned off after the reset.
