Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal and wait at least 10 minutes to discharge the airbag system.

2. Inspect and Replace Fuses

Locate the fuse box (refer to the owner’s manual for exact location).
Identify the airbag system fuse and remove it.
Inspect the fuse for continuity using a multimeter; replace if blown.
Reinstall the fuse and reconnect the battery.

3. Check and Repair Wiring and Connectors

Visually inspect all wiring and connectors leading to the airbag system.
If any connectors are loose, clean and securely reconnect them.
If any wires are damaged, repair or replace as necessary using appropriate connectors.

4. Test the Airbag System

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position without starting the engine and observe the airbag light.
If the light goes off after a few seconds, the system is functioning properly.
If the light remains on, further diagnosis may be needed with professional equipment.
