Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, and battery terminal wrench.
Ensure the vehicle is parked in a safe location with the engine off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's OBD-II port (usually located under the dashboard on the driver's side).
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to retrieve any stored fault codes.
Note any codes for potential repairs.

3. Disconnect the Battery

Use a socket set to loosen the negative battery terminal.
Carefully remove the negative terminal and ensure it does not come into contact with the battery.
Wait for at least 5 minutes to allow the vehicle’s systems to reset.

4. Reconnect the Battery

Reattach the negative battery terminal and tighten it securely with a socket.
Ensure the connection is clean and free of corrosion.

5. Verify Reset

Start the vehicle and check the dashboard for the check engine light.
If the light is still on, use the OBD-II scanner to clear the fault codes stored in the system.
