1. Preparation

Gather the necessary tools: OBD-II scanner, socket set (if battery disconnect is used), and gloves.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Using an OBD-II Scanner

Connect the OBD-II scanner to the vehicle's OBD-II port, typically located under the dashboard near the steering column.
Turn on the ignition without starting the engine, allowing the scanner to power up.
Follow the scanner's prompts to retrieve and record any diagnostic trouble codes (DTCs).
Perform necessary repairs based on the codes if applicable.
Select the option to clear or erase codes within the scanner's menu.

3. Disconnecting the Battery (if applicable)

Turn off the ignition and ensure all electrical accessories are off.
Open the hood and locate the battery.
Using a socket wrench, carefully disconnect the negative (-) terminal first, followed by the positive (+) terminal.
Wait for 10-15 minutes to ensure all systems reset.
Reconnect the terminals, starting with the positive (+) terminal, followed by the negative (-).
Close the hood and start the vehicle to check if the light has reset.
