Turn the ignition to the "ON" position without starting the engine.
Record any retrieved trouble codes and consult service manuals for specific diagnostics related to those codes.

3. Inspect and Repair Wiring

Reconnect the battery temporarily to test the airbag system.
Visually inspect the airbag wiring harness for any frays, breaks, or loose connections.
Repair any damaged wiring using appropriate connectors and heat-shrink tubing to ensure a secure repair.

4. Check Seatbelt Sensors

Remove the seatbelt buckle cover to access the sensor.
Disconnect the wiring harness and check for corrosion or damage.
Replace the seatbelt buckle sensor if it shows signs of malfunction.

5. Clear Codes and Test
