What to Do When Your See Service Soon Light

If you don’t have a diagnostic tool with you to check what’s wrong in situations like this, you’ll need to check things that will commonly bring up this message.

Note: An OBD2 diagnostics code read (View on Amazon) will give you the meaning of an error code and it will allow you to reset them then and there’. The tool connects to the OBD port which will allow the software to determine what the problem with your car is.

There are some common things you should check If you haven’t got a diagnostics tool but before you do so, the color of the warning can give you a lot of clues. If you get a yellow light, this means that the problem is minor, and you’ll be able to diagnose the problem yourself or drive to a nearby workshop to get it checked out.

If the color of the warning is red, then there’s a major problem going on and you should turn off your car’s engine as soon as possible. If you aren’t a few seconds away from a mechanic shop, you’ll need to call a service to get your car towed to a shop so it can be diagnosed properly there.

Some manufacturers have a separate check engine light along with a service light. If you do see the check engine, then the engine control unit or your transmission control unit has detected a problem with your engine.

If your check engine light comes on rather than the service engine light, then you can use your OBD2 scanner to check the code. If the check engine light did light up, then a scheduled service shouldn’t be due because the check engine light doesn’t come up if there is a scheduled service.

Things to Check For

If you have your car’s manual and you know that the problem is minor, then you can check what the check engine soon light means. This is the best way to check what could be wrong with your car before taking it to the mechanic.

1. Check the fuel tank to see if the cap is tightened. If not, this can cause the light to come on which will prevent any spillage which could lead to further problems. Once you’ve done this, you’ll need to drive your car a few times so that the OBD2 reader notices problem is solved and therefore turn off the SES light. If the light does remain on in this case, then you may need to replace your gas cap.

2. If our Oxygen sensor is faulty, this can cause the light to come on. Your car needs to have the correct ratio of oxygen to gasoline. If there’s too little oxygen, this can damage the engine, the same as if there’s too much oxygen. There’s a sensor that can detect if the ratio is correct. If the sensor is faulty and it cant adjust the ratio properly, the light can come on.

3. Check your car’s fluid levels including the brake fluid, oil, widow wiper fluid, and automatic transmission fluid. Lower levers of any fluid can trigger the light to come on depending on your car’s manufacturer.

4. Check the anti-lock brake of the safety restraint system.

5. Check if any seat belts are broken. Because of safety issues, a broken seat belt can trigger the light because this can be a danger to someone’s life.

6. This light could also mean that your car’s battery is bad, or you have a broken alternator.
