Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
Disconnect the negative battery terminal and wait at least 10 minutes to allow the system to discharge.

2. Retrieve and Analyze Codes

Use the OBD-II scanner to read any stored DTCs related to the SRS system. Document the codes for reference.
Research the codes to determine specific faults in the airbag system.

3. Inspect SRS Components

Airbag Module: Remove the dashboard cover to access the airbag control module. Check for loose connections or corrosion.
Seatbelts and Buckles: Inspect the seatbelt buckles for proper operation and wiring integrity. Look for frayed wires or poor connections.
Airbag Connectors: Carefully inspect airbag connectors under the seats and steering wheel. Ensure they are securely connected.

4. Repair or Replace Faulty Components

If any components are found faulty, replace them with OEM parts. Ensure that all connectors are clean and free of corrosion.
Reconnect the airbag control module and other components, ensuring proper torque specifications are followed (typically around 7-9 ft-lbs for electrical connectors).

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored trouble codes.
Start the vehicle and observe if the SRS light remains off. If not, further diagnostics may be required.
