Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Wait at least 10 minutes to allow the airbag system to discharge.

2. Inspect Wiring and Connectors

Visually inspect the driver's side airbag connector and wiring harness:
- Remove any protective covers if necessary.
- Look for frays, cuts, or corrosion.
If issues are found, repair or replace the damaged wiring or connectors as needed.

3. Test Airbag Resistance

Reconnect the battery temporarily to measure the airbag resistance:
- Use a multimeter set to the ohm setting.
- Connect the probes to the airbag connector terminals.
- Compare the resistance reading to the manufacturer's specifications (typically between 2 to 3 ohms).
If the resistance is out of spec, replace the airbag.

4. Check Seat Belt Pretensioner

Inspect the seat belt pretensioner wiring and connector.
Test the pretensioner using a multimeter to ensure it is functioning within specifications.
Replace the pretensioner if it is faulty.

5. Reassemble and Clear Codes

Reconnect all connectors and wiring.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the B0010 code.
Perform a test drive to ensure the issue is resolved.
