Gather necessary tools: OBD-II scanner, socket set, and multimeter.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety glasses and gloves for protection.

2. Inspect and Clean Sensors

Locate the blind spot monitoring sensors, typically found on the rear corners of the vehicle.
Inspect each sensor for any obstruction or damage.
Clean the sensors using a microfiber cloth and appropriate cleaning solution if dirty.

3. Reset the System

If applicable, navigate to the vehicle settings using the dashboard display and find the blind spot monitoring options.
If no setting is available, proceed to disconnect the battery:
- a. Use a socket set to remove the negative terminal first, followed by the positive terminal.
- b. Wait for at least 5 minutes to allow the system to reset.
- c. Reconnect the positive terminal followed by the negative terminal, ensuring connections are tight.

4. Check for DTCs

Reconnect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the 'ON' position without starting the engine.
Scan for any codes related to the blind spot monitoring system and clear them if found.
