If all of your car’s warning lights are on and your dashboard warning light system seems to be malfunctioning, you’ll need to temporarily disconnect the battery. To do so, open the hood of your car. Then locate the battery terminal. You’ll want to disconnect the negative (-) terminal. Be extremely careful when doing so, as touching the negative and positive terminal at the same time can shock you.
Once you disconnect the battery, leave it disconnected for about ten minutes. Then, reconnect the negative battery terminal and secure it by tightening the nut. By doing this, your Toyota warning lights should be reset. If the problem persists, you will need to take your car to a mechanic.
