WARNING: Disconnecting the battery cable can erase important electronic settings, such as radio station presets and clock settings. So follow the steps carefully and reconnect the battery terminal within the specified time.
1. Turn Off Engine: Park the car in a safe location, turn off the engine, and allow it to cool down.
2. Open Hood: Open the hood of the vehicle to access the engine compartment.
3. Locate Battery: Find the car battery. The battery is usually enclosed within a plastic casing.
4. Disconnect Negative Terminal: Use a wrench or socket set to loosen the nut/bolt that secures the negative battery terminal (marked with "-") to the battery post.
5. Maintain Disconnection: Keep the negative terminal disconnected for at least 10 seconds to 15 seconds. This will discharge any residual electrical charge stored in the vehicle's electrical system.
6. Reconnect Negative Terminal: After the specified time, reconnect the negative terminal to the battery post. Tighten the nut/bolt securely to ensure a proper connection.
7. Start Engine: Get back into your car and start the engine.
8. Observe Check Engine Light: Monitor the instrument cluster. If the Check Engine Light turns off, the reset has been successful.
NOTE: If the Check Engine Light remains illuminated after following these steps, it might indicate an underlying issue with your vehicle's engine or emissions system. In this case, we recommend scheduling a diagnostic inspection at a reputable auto repair shop or dealership to identify the exact cause and have it addressed appropriately.
