If you are a DIY car enthusiast, you may like a diagnostic scan tool. Such a tool can be a real friend for you. It can save your costs and your car too. It can show error codes thrown up by the OBDII for various systems and subsystems of your car. It not only indicates the location and type of fault, but also guides you to resolve the problem. You can really get some much needed help from this tool. It acts much like the neighborhood friendly workshop mechanic. Since, it can throw up errors through trouble codes, you can get a glimpse into the working of the subsystems of your car. Even if it does not throw up an error code, you can spot anomalies in Serial Data View mode. There are some anomalies that don’t show up through codes. However, there may well be some anomaly in the working condition of various parts. 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. This can be done if you view the corresponding data in Serial View. This option is there in an advanced diagnostic scan tool. However, to interpret such data you need to be comfortable with operating conditions and parameters of various systems and subsystems of an automobile.
Functionalities of A Diagnostic Scan Tool
The basic function of a diagnostic scan tool is to read the error codes shown by the On Board Diagnostic computer. But today’s scan tools are more about interactivity and intelligence than just showing error codes. These are not like the dumb devices of yesteryears. These tools can not only read trouble codes, but also analyze them and suggest ways to resolve the problem. They can also guide you to solve the problem. This is the biggest help that you can get from the device. But in order to serve this purpose and also for other purposes, a modern diagnostic scan tool is capable of many other functions. It is able to erase data, show current operating data in parameter as well as graphic mode etc. You can also group the parameters manually. The device can identify a system with the System identification app. 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. With sensor calibration you can ensure that the sensors are working perfectly. The ability to program is a great utility of such tools. You can program the fuel injector so that it injects fuel in accordance with the manufacturer’s specifications. You can also program the keys and the remote if need be. 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. 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. 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. You may have changed engine oils, yet the OBD II is showing Change Engine Oils soon. This happens since the sensor can detect the changed oil or other services only after few drive cycles. In such a condition a service reset option is very handy. You can use the Service Reset option in every item.

How Does It Look Like
The automotive scan tool comes with a tablet PC running either on Windows or iOS. It is much like a tablet or a smartphone. The user interface is littered with options or apps. You just need to choose your option. It comes with a Data Link Connector popularly known as DLC, a power cable and some other components. The software for carrying out the job is installed in the tablet. You need to update this software on a regular basis. The frequency of updates depends on the type of tool, the company etc. In some companies the updates cost nothing, in others you may need to pay for updating. Without updates, the tool is not likely to perform satisfactorily.
