Wait at least 10 minutes to allow the SRS system to discharge.

2. Inspect and Repair Wiring

Airbag Connector Inspection:
- Locate the airbag connectors under the front seats and inspect for damage or corrosion.
- Clean connectors with electrical contact cleaner if corroded.
- Re-secure or replace connectors as needed.
Seat Belt Switch Check:
- Remove the seat belt buckle cover.
- Check for continuity in the seat belt switch using a multimeter.
- Replace the switch if it shows no continuity.

3. Reset SRS Light

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear the SRS fault codes.
Turn the ignition to the "On" position (do not start) and check if the SRS light remains off.
