Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, electrical contact cleaner, safety goggles, gloves.
Disconnect the negative battery terminal and wait at least 10 minutes to allow the airbag system to power down.
Wear safety goggles and gloves for protection.

2. Inspect Wiring and Connectors

Sub-steps:
1. Remove the driver's side lower dash panel to access the airbag connectors.
2. Visually inspect the wiring harness for frays, cuts, or corrosion.
3. Ensure all connectors are firmly seated and free of corrosion.
4. Clean any corroded terminals using electrical contact cleaner.

3. Check Airbag Module and Grounding

Sub-steps:
1. Locate the airbag control module, usually beneath the center console or near the driver's seat.
2. Verify that the module is securely mounted and check for any physical damage.
3. Using a multimeter, check the ground connection for continuity.
4. Ensure that the power supply to the airbag module is functioning correctly.

4. Test and Replace Airbag Component

Sub-steps:
1. Disconnect the driver's airbag connector by pulling the release tab.
2. Measure the resistance of the airbag using a multimeter; it should be within manufacturer specifications (typically 2-3 ohms).
3. If resistance is out of range, replace the driver's airbag with a new unit.
4. Reconnect the airbag connector securely.

5. Clear Codes and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear the B0010 code from the airbag control module.
3. Start the vehicle and verify the airbag warning light is off.
4. Conduct a test drive to ensure the airbag system is functioning properly.
