Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative terminal of the battery to prevent accidental airbag deployment.

2. Scan for Trouble Codes

Connect an OBD-II scanner to the diagnostic port located under the dashboard.
Record any trouble codes related to the airbag system.

3. Inspect Wiring and Connections

Remove the front seats if necessary to access the wiring harnesses.
Visually inspect for frayed wires, loose connections, or corrosion.
Repair or replace any damaged wiring or connectors as needed.

4. Check Airbag Control Module

Locate the airbag control module, typically found under the center console or passenger side dash.
Ensure the module is securely connected and free from damage.
If necessary, replace the control module according to manufacturer specifications.

5. Test Components

Use a multimeter to test the resistance of the airbag and seatbelt pretensioners.
Ensure the readings are within the specifications provided in the service manual.
Replace any components that do not meet specifications.

6. Reconnect Battery

Reconnect the negative terminal of the battery.
Turn the ignition to the ON position without starting the engine to check if the airbag warning light turns off.
