Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather tools: OBD-II scanner, socket set, and possibly a multimeter for further diagnostics.

2. Use 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.
Navigate to the "Read Codes" section and note any error codes.
If no codes are present or after addressing existing codes, proceed to the reset function.

3. Reset Check Engine Light

In the OBD-II scanner menu, select the option to "Erase Codes" or "Clear Codes."
Confirm the action and wait for the scanner to complete the process.

4. Battery Disconnect (if necessary)

If the OBD-II scanner does not reset the light, turn off the ignition.
Using a socket set, loosen the negative battery terminal clamp and disconnect it.
Wait for at least 15 minutes to ensure the vehicle's computer resets.
Reconnect the negative battery terminal and tighten the clamp securely.

5. Test

Start the engine and observe the dashboard for the check engine light.
Ensure that the light is off and monitor for any abnormal engine behavior.
