Gather all necessary tools and parts for the repair.

2. Inspect and Repair Wiring

Remove the driver's seat to gain access to the airbag wiring harness.
Inspect the wiring harness for any signs of damage, such as fraying or cuts.
If damage is found, repair the wiring using appropriate connectors and heat-shrink tubing.
Ensure all connections are secure.

3. Replace Airbag Control Module (if necessary)

If the airbag control module is determined to be faulty, remove it from its mounting.
Disconnect the wiring harness from the airbag control module.
Install the new airbag control module by reversing the removal process.
Secure the module in place and reconnect the wiring harness.

4. Reconnect Battery and Clear Codes

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear the B0030 code and any other stored codes.
Ensure that the airbag warning light goes out.

5. Test Airbag System

Conduct a thorough test of the airbag system by performing a diagnostic scan to check for any new codes.
Ensure the airbag warning light operates correctly during ignition and extinguishes after engine start.
