Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, gloves
Ensure the vehicle is parked on a level surface and the engine is off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port, usually located under the dashboard near the steering column.

If the check engine light remains on after clearing codes, turn off the ignition.
Using a socket set, disconnect the negative (-) battery terminal.
Wait for at least 10 minutes to allow the vehicle's systems to reset.
