Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative terminal of the battery and wait at least 10 minutes to ensure airbag systems are deactivated.
Required tools: OBD-II scanner, multimeter, socket set, torque wrench, and a flathead screwdriver.

2. Retrieve and Clear Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition on without starting the engine.
Retrieve and note any SRS error codes.
Clear the codes and check if the SRS light returns after a test drive.

3. Inspect and Repair Wiring/Connectors

Inspect the airbag connectors under the front seats, steering column, and dashboard.
If any connectors are loose or corroded, clean and secure them properly.
Use a multimeter to test the continuity of wires leading to the airbags and seatbelt tensioners.

4. Replace Faulty Components

If any components (like seatbelt pre-tensioners or airbag modules) are identified as faulty during inspection:
- Disconnect the battery again.
- Remove the affected component using the appropriate socket set.
- Install the new component, following manufacturer specifications for torque and connection.

5. Reconnect Battery and Final Checks

Reconnect the negative terminal of the battery.
Turn on the ignition and check if the SRS warning light is still illuminated.
If the light is off, perform a final inspection of all airbag components.
