In such a condition a service reset option is very handy. This happens since the sensor can detect the changed oil or other services only after few drive cycles. You may have changed engine oils, yet the OBD II is showing Change Engine Oils soon. A service reset is a very useful function for any scan tool since without it you are stuck with a Service Now message for various services even if you have serviced them many times over. A diagnostic scan tool does help the owner a lot, but only if the owner is very much conversant and comfortable with various systems and their working parameters. However, for all these and especially for sensor calibration and programming of various components, you need to be quite adept at everything related to automobiles. You can also program the keys and the remote if need be. You can program the fuel injector so that it injects fuel in accordance with the manufacturer’s specifications. The ability to program is a great utility of such tools. With sensor calibration you can ensure that the sensors are working perfectly. In can also calibrate the sensors, Since the sensors are the ones that send the data to the OBD II, they need to throw up proper working data. The device can identify a system with the System identification app. You can also group the parameters manually. It is able to erase data, show current operating data in parameter as well as graphic mode etc. But in order to serve this purpose and also for other purposes, a modern diagnostic scan tool is capable of many other functions. This is the biggest help that you can get from the device. They can also guide you to solve the problem. These tools can not only read trouble codes, but also analyze them and suggest ways to resolve the problem.
These are not like the dumb devices of yesteryears. But today’s scan tools are more about interactivity and intelligence than just showing error codes.
The basic function of a diagnostic scan tool is to read the error codes shown by the On Board Diagnostic computer. However, to interpret such data you need to be comfortable with operating conditions and parameters of various systems and subsystems of an automobile.įunctionalities of A Diagnostic Scan Tool This option is there in an advanced diagnostic scan tool.

This can be done if you view the corresponding data in Serial View.

For example the fuel leakage error code may not show if the leakage is miniscule, yet the reading of various data regarding fuel use, fuel combustion, thrust etc may expose the anomaly. However, there may well be some anomaly in the working condition of various parts. There are some anomalies that don’t show up through codes. Even if it does not throw up an error code, you can spot anomalies in Serial Data View mode. Since, it can throw up errors through trouble codes, you can get a glimpse into the working of the subsystems of your car. It acts much like the neighborhood friendly workshop mechanic. You can really get some much needed help from this tool.
It not only indicates the location and type of fault, but also guides you to resolve the problem. It can show error codes thrown up by the OBDII for various systems and subsystems of your car. Such a tool can be a real friend for you. If you are a DIY car enthusiast, you may like a diagnostic scan tool.
