Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers).
Park the vehicle on a flat surface and turn off the ignition.
Disconnect the battery, allowing it to sit for at least 10 minutes to discharge any residual power.

2. Inspect Wiring and Connectors

Sub-steps:
1. Remove the driver's seat if necessary to access the connectors underneath.
2. Check all airbag connectors for corrosion, bent pins, or loose connections.
3. Use a multimeter to test continuity in the wiring harness from the airbag module to the individual airbags.

3. Replace Blown Fuses

Sub-steps:
1. Locate the fuse box; refer to the owner's manual for the exact location.
2. Remove the SRS fuse and inspect it; replace it with a new fuse of the same amperage if it is blown.

4. Reset Airbag System

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any stored airbag fault codes.
3. Turn the ignition to the ON position without starting the engine, and observe whether the airbag light goes off after a few seconds.

5. Test the System

Sub-steps:
1. Perform a self-check of the airbag system by turning on the ignition and ensuring the airbag light illuminates briefly and then turns off.
2. Conduct a test drive to confirm the airbag system is functioning correctly without any warning lights.
