Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.
Allow the vehicle to sit for at least 10 minutes to ensure capacitors discharge in the airbag system.

2. Scan for Fault Codes

Use an OBD-II scanner to retrieve any fault codes from the airbag control module.
Document any codes for further analysis.

3. Inspect Connectors and Wiring

Locate the airbag module, typically under the center console or dashboard.
Carefully disconnect the airbag connectors and check for corrosion or bent pins.
Clean connections with electrical contact cleaner if necessary and reconnect securely.

4. Check Battery and Ground Connections

Use a multimeter to measure the vehicle's battery voltage; it should be between 12.4V and 12.7V.
Inspect ground connections under the dash and ensure they are clean and secure.

5. Replace Faulty Components (if applicable)

If fault codes indicate a specific faulty component (e.g., airbag module, seat belt tensioner), order the replacement part.
Follow manufacturer specifications for installation.

6. Clear Fault Codes

Once repairs are completed, use the OBD-II scanner to clear the fault codes.
Reconnect the negative battery terminal.
