1. Disconnect the battery: First, disconnect the negative (black) cable from the battery. This will cause a loss of power to the vehicle, which is necessary for resetting the check engine light.
2. Wait for 10-15 minutes: After disconnecting the negative cable, wait for at least 10-15 minutes. This allows the vehicle's electrical systems to fully discharge and reset.
3. Reconnect the battery: Once you've waited, reconnect the negative cable back to the battery. You might hear a clicking sound as power returns to the vehicle.
4. Turn on the ignition: Without starting the engine, turn the ignition key to the "ON" position. This powers up the vehicle's electrical system without actually starting the engine. Leave the key in this position for a few seconds.
5. Start the engine: After a few seconds, start the engine normally. The check engine light should be off if it was a temporary or minor issue that caused the light to come on.
If the check engine light stays on after following these steps, it indicates a more severe issue that requires diagnosis by a qualified mechanic. In that case, it is recommended to take your car to a reputable auto repair shop for proper diagnostics and repairs.
