Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.
Allow the vehicle to sit for at least 10 minutes before working on the SRS to ensure capacitors discharge.

2. Inspect and Repair Wiring

Remove the lower dashboard cover to access the airbag module and wiring.
Inspect the wiring harness for damage, fraying, or corrosion.
Repair any damaged wires using solder or heat shrink tubing, ensuring connections are secure.

3. Replace Faulty Components

If the diagnostic scan indicated a specific faulty component (e.g., an airbag sensor), proceed to replace it:
1. Disconnect the electrical connector from the faulty component.
2. Remove any bolts or fasteners securing the component in place.
3. Install the new component in the reverse order of removal.
4. Reconnect the electrical connector securely.

4. Clear Trouble Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any trouble codes stored in the airbag system.
Start the vehicle and check if the airbag warning light remains off.
