An OBD2 Code Reader is a device, which is used to read and decode the diagnostic codes generated by the OBD (On-board Diagnostic Data Exchange) system of a car. The OBD2 codes determine a car’s problem status and can be accessed with the help of this scanner. There are different types of scanners available in the market, like OBD-S (orsemetically readable), OBD-T (temperature sensitive), and OBD-E (Electronic Brake-force Distribution). A scanner is a small computer that can take the diagnostic information and translate it into a meaningful code.
Like all other devices manufactured by some of the leading companies, an obd2 code reader comes with a number of cons. Most people prefer buying newer scanners, as they have more advanced functionalities and perform better than their predecessors. Even though the newest gadgets are more expensive, most of them are working perfectly fine. However, there are a few cons associated with almost all electronic devices, which have been analyzed and discussed below.
One of the common problems associated with OBD2 scanners is that they cannot interpret the codes generated for the most recent vehicles. Almost all the cars produced have a specific version of the OBD2 scanner. As a result, if the scanner cannot interpret the codes generated for a particular model, it will not be able to offer you assistance regarding the malfunctioning of your car. Since most of the car owners are not aware about the specific version of their cars, this becomes their biggest disadvantage. Thus, most of the car owners rely on the manufacturers of their cars to provide proper support regarding the pending codes.
Another important drawback of the OBD2 code reader is that it consumes a lot of battery power. This is the reason why most of the scanners use a USB cable to connect with the computer. If you are trying to scan something and if your computer has run out of battery power, then the information provided by the OBD2 scanner will not be available. Most of the handheld diagnostic scan tools use the latest USB technology to ensure that the scanning process is quick and provides real time information.
However, the modern version of the OBD2 scanner is designed in such a way that it does not require any external power supply. The scanner functions properly even when the car engine is running. There are different versions of the OBD2 code reader manufactured by different companies such as OBDechek, OBDopy, and the new generation product manufactured by the German company Autel Maxilink. The OBD2 scanner can be used to check engine lights for the cars running under normal conditions. It can also be used to diagnose various problems associated with the electronic control system of the vehicle.
If you have an obd2 scanner, then you can check engine lamps, odometer, fuel level, tire pressure, oil level and more through the scanner. There are various types of the OBD2 scanner that you can purchase. The most commonly used is the handheld unit that has to be placed in the vehicle on which the OBD2 codes are to be read. The other type of OBD2 scanner is the vehicle mounted scanner which is attached to the vehicle and connected to a computer via the USB cable. There are also computer-based OBD codes scanners manufactured by Mercedes Benz, BMW and others. The handheld and vehicle mounted scanners work in a similar fashion although the latter is more accurate and faster.
Before you buy an OBD scanner, find out what kind of compatible scanners are available. Most of these scanners can read all the major brands of fuels. However, some scanners may only support a limited range of fuels. Make sure that you do not compromise on the compatibility of the scanner with the kind of vehicle you own because once you enter the unknown codes, it could be a life saver if you have a faulty vehicle or do not know which fuel the car needs.
Nowadays, many leading mobile phones come with built-in OBD2 scanners. This allows drivers to scan the engine and troubleshoot any technical problem automatically. The best scanners allow users to scan the engine and use their handsets to control the scan functions. By using one of the best scanners, you can solve technical problems such as low fuel levels in vehicles, irregular speed and poor performance and even detect common engine defects.
