Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Inspect Wiring and Connectors

Sub-steps:
1. Remove the driver's side lower dash panel to access the airbag system connectors.
2. Visually inspect all connectors for corrosion, bent pins, or loose connections.
3. Use a multimeter to check for continuity in the wiring harness leading to the airbag module.
4. Reconnect any loose or damaged connectors after repair.

3. Replace Faulty Components

Sub-steps:
1. If any fault codes indicate a specific sensor (e.g., seatbelt sensor), remove the faulty component using a socket set.
2. Install the new component, ensuring all connections are secure.
3. Torque the mounting bolts to the manufacturer's specifications (check service manual for exact values).

4. Reset Airbag System

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear all fault codes.
3. Turn the ignition key to the "ON" position without starting the engine to check if the airbag light turns off.
