Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Inspect and Replace Fuses

Locate the fuse box; refer to the owner's manual for the exact location.
Remove the airbag system fuse and inspect it for continuity.
If blown, replace it with a fuse of the same amperage rating.

3. Check and Repair Connections

Reconnect the negative battery terminal.
Access the airbag module and inspect connectors for tightness and corrosion.
For under-seat wiring, remove the seat if necessary to gain access.
Repair or replace any damaged or corroded connectors.

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Follow the scanner instructions to clear any stored airbag codes.
Confirm the airbag light turns off; if it remains on, further investigation is required.
