Solution

1. Preparation

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

2. Retrieve and Analyze Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position without starting the engine.
Retrieve any stored airbag system fault codes.
Document the codes for further analysis.

3. Inspect and Repair Connections

Seatbelt Buckle Connections:
- Remove the seat covers if necessary to access the seatbelt buckle connectors.
- Disconnect the connectors and inspect for dirt or corrosion.
- Clean or replace connectors as needed.
Airbag Module Connections:
- Locate the airbag control module (usually under the center console or dashboard).
- Disconnect the module's connectors and inspect for damage.
- Clean connections and reconnect securely.

4. Check Airbag Circuit Continuity

Using a multimeter, check for continuity in the airbag circuits, focusing on the driver's and passenger's airbags.
Repair any broken wires or replace damaged components.

5. Verify SRS Fuse

Locate the fuse box and find the SRS fuse.
Check if the fuse is blown using a multimeter.
If blown, replace with the same amperage fuse and recheck the airbag system.

6. Reset Airbag System

After repairs, reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag fault codes.
Turn the ignition ON and check if the airbag light turns off.
