Having your own auto scan tool can help you save money and time by avoiding an unneeded trip to the dealership or automotive repair center for diagnosis. It is very common these days to have your service engine soon light just pop on. The monitoring system that activates the light is very sensitive.
Resetting check engine lights is a simple procedure. But first I'll give you a little background on what turns on the service engine soon light and why the light exists at all.
The service engine soon light comes on to notify the driver that a code has been set in memory. Sometimes the code relates to a serious problem, but in most cases it's a minor malfunction or intermittent condition. If you have your own auto scan tool. You can answer the number one question in everyone's mind when that service engine soon light comes on. Of course the question is, why is this light on and how to reset check engine light codes. An auto scan tool can give you the answer quickly and easily.
All you have to do is plug in an auto scan tool, and it will pull a code from the computer that points to the system malfunction and will give you the option to reset the check engine light.
Auto scan tool reason number two
When a service engine soon light is turned on, and you take your vehicle to the dealership. The first thing they do is connect a scanner to retrieve the code.
They take this code and look it up in their auto service manual. In most cases, the first step in diagnosing any code is to clear or reset the check engine light code and see if it returns as a hard failure. If the auto repair center clears the code, and it does not return, the problem is considered intermittent. In this scenario, you have just been charged at lease one-hour diagnosis for little or no auto repair help. If you had your own scan tool, you would be able to retrieve and record the code and then clear the code to see if it was an intermittent problem. If the service engine soon light does not come back on. You have just repaired your vehicle in a span of about 10 minutes. You have also just avoided a trip to the auto repair center, which is priceless. If the service engine soon light comes back on, you will be able to reconnect the auto scan tool and verify that the same code as been set. You would then diagnose the code yourself using an online repair diagram such as All-Data auto repair manuals. Or you can even take the vehicle to your repair center, but with the information that the auto scan tool has provided for you. This can cut down on the shop's initial diagnosis. You have already cleared the codes and done the first major step of diagnosis for the auto repair center, this will save you money on diagnostic charges. Auto scan tool reason number threeOne of the most common reasons for the service engine soon light to come on is the number one nuisance code for fuel system vapor leak.As of 1996 federal emission laws require the manufacturer to lightly pressurize the fuel system to check for vapor leaks. The vehicle's computer performs this pressure test automatically every time you turn on the key. If you have just filled up your gas tank, and not tightened the fuel cap. The computer will see this as a fuel system leak and illuminate the service engine soon light. The above scenario is not on every vehicle, but on most.
You can connect your auto scan tool and pull the code and see if it is the fuel system leak code. You can then go around and check your gas cap for tightness and then clear the code. You can then continue to operate the vehicle and if the light stays off, once again you have just repaired your own car in a span of about 10 minutes. If the check engine light does come back on again you have cut down the diagnosis time for the repair center and saved yourself some time and money.
I have been using diagnostic equipment for the last 23 years. In 1996, the federally mandated deployment of the obd 2 diagnostic system has changed the way the auto scan tool is used.
