Read and note any DTCs related to the airbag system.
Clear the codes using the scanner, then turn the ignition off.

3. Inspect Components

Reconnect the battery terminal.
Visually inspect the connectors and wiring related to the airbag system under the dashboard and seats.
Use a multimeter to check for continuity in the airbag wiring harness.
Ensure all connectors are secure and free from corrosion.
