Solution

1. Preparation

Gather tools and safety equipment.
Disconnect the vehicle's battery and wait at least 10 minutes for the airbag system to discharge.

2. Inspect and Repair Wiring

Tools Required: Wire strippers, soldering iron, heat shrink tubing.
Carefully inspect the wiring harness leading to the driver-side airbag for any signs of damage or corrosion.
If damaged, cut out the faulty section, strip the wires, and solder in new wire. Seal with heat shrink tubing to avoid moisture intrusion.

3. Replace Airbag Module (if necessary)

Tools Required: Socket set, torque wrench.
Remove the steering wheel using a socket set to access the airbag module.
Disconnect the airbag wiring harness from the module.
Replace the airbag module with a new one, ensuring the connector is secure.
Reinstall the steering wheel and torque to manufacturer specifications (typically around 35 Nm).

4. Clear Codes and Test

Reconnect the battery and use the OBD-II scanner to clear the B0010 error code.
Start the vehicle and verify that the airbag warning light is no longer illuminated.
