Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and a torque wrench.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Allow the vehicle to sit for at least 10 minutes to ensure system discharge.

2. Inspect and Repair Wiring

Remove the front seat(s) if necessary to access wiring connections.
Visually inspect the airbag wiring harness for frays, breaks, or loose connections.
Use a multimeter to test for continuity in the wires. Repair or replace damaged wiring as needed.

3. Replace Faulty Components

If diagnostic trouble codes indicate a specific component failure (e.g., a seatbelt pretensioner), replace the faulty component.
Follow manufacturer specifications for torque settings when installing new components.

4. Reconnect and Test

Reconnect any disconnected components and wiring.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any trouble codes.
Start the vehicle and check if the SRS light turns off.
