Remove the airbag module:
- Use a socket set to remove screws securing the airbag module to the steering wheel.
- Carefully detach the airbag connectors; ensure no damage occurs to the wires.
Remove the steering wheel:
- Use a steering wheel puller if necessary to avoid damaging the column.
- Remove the central nut, then pull the steering wheel off the column.

3. Inspect and Clean Connections

Visually inspect the wiring harness connected to the steering wheel controls for any damage.
Clean the connectors with electrical contact cleaner to remove any corrosion or dirt.
Reconnect any loose connectors securely.

4. Reset the Steering Control Module

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any trouble codes that may be present.
Perform a reset of the steering control module through the scanner if the option is available.

5. Reassemble Components

Reattach the steering wheel by aligning it correctly on the column and tightening the central nut to the manufacturer’s specified torque (typically around 30-35 ft-lbs).
Reconnect the airbag module, ensuring all connectors are secure.
Reattach any screws removed during disassembly.
