Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to avoid accidental deployment of airbags.
Allow the vehicle to sit for at least 10 minutes to ensure the system discharges.

2. Retrieve and Address Diagnostic Codes

Use the OBD-II scanner to pull airbag-related DTCs.
Research the codes and determine if they indicate specific sensors or faults.
Clear the codes after any necessary repairs are made to reset the system.

3. Inspect the Airbag System

Visually inspect the airbag module and surrounding components for any visible damage.
Check all connectors related to the airbag system and reseat any loose connections.
Replace any damaged wiring or connectors identified during the inspection.

4. Test Sensors and Control Module

Follow the manufacturer’s service manual to test each airbag sensor for proper resistance and functionality.
Ensure the airbag control module is securely mounted and free from moisture.

5. Reconnect Battery and Test System

Reconnect the negative battery terminal.
Start the vehicle and monitor the airbag light for activity; it should turn off within a few seconds if the system is functioning correctly.
