2. Inspect Wiring and Connectors

Remove the lower steering column cover using a socket set.
Visually inspect the airbag connectors and wiring for any signs of wear, corrosion, or loose connections.
Reconnect any loose connectors securely.

3. Check Seatbelt Pretensioners

Access the seatbelt pretensioner connectors located near the seat.
Disconnect the seatbelt pretensioner connector and check for continuity using a multimeter.
Replace the pretensioner if it fails the continuity test.

4. Inspect the Airbag Control Module

Locate the airbag control module, usually found under the center console or under the driver's seat.
Disconnect the module and inspect for corrosion or damage.
If damaged, replace the airbag control module with a new one, ensuring it is compatible with the Genesis G70.

5. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Start the vehicle and check for the airbag warning light status.
If the light remains on, repeat DTC scanning and further diagnostics as necessary.
