Solution

1. Preparation

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

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire strippers, electrical tape
Inspect the airbag wiring harness for any signs of fraying or damage.
Use a multimeter to test continuity across the wiring. Repair any broken wires by stripping and reconnecting them, ensuring a secure connection.
Use electrical tape to insulate any exposed wires.

3. Replace Faulty Sensors

Tools Required: Socket set, screwdrivers
If seatbelt sensors or airbag module show faults, replace them with OEM parts.
Disconnect the faulty sensor, install the new sensor, and ensure all connections are secure.

4. Reconnect Battery and Test

Reconnect the vehicle’s battery and turn on the ignition without starting the engine.
Check if the airbag light remains illuminated.

5. Final Testing

Start the vehicle and observe the airbag light status.
Test the airbag system functionality by performing any available onboard diagnostics.
