1. Preparation

Tools Required: OBD-II scanner, torque wrench (if required for seat removal), socket set, multimeter.
Disconnect the vehicle battery's negative terminal to ensure safety while working on the airbag system.
Allow the vehicle to sit for at least 10 minutes to allow any residual charge in the airbag system to dissipate.

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Navigate to the airbag system section in the scanner and select the option to clear fault codes.
Follow the prompts on the scanner to confirm the deletion of codes.
Disconnect the scanner after the process is complete.

3. Reconnect Battery

Reconnect the negative terminal of the battery.
Ensure it is securely tightened to prevent any disconnection during vehicle operation.
