1. Locate the diagnostic connector under the dashboard, usually near the driver's side.
2. Connect a jumper wire between the ground (GND) and the self-diagnosis (SD) terminals of the diagnostic connector.
3. Turn on the ignition switch, but do not start the engine.
4. Wait for the check engine light to come on and then turn off.
5. Turn off the ignition switch and remove the jumper wire.
6. Start the engine to verify that the check engine light remains off.
If the check engine light remains on after following these steps, it indicates an underlying issue that requires further diagnosis and repair. It is recommended to consult with a qualified mechanic or refer to the vehicle's service manual for specific troubleshooting instructions.
