Top 10 Best OBD2/ OBDII Scanners

Top 10 Best OBD2/ OBDII Scanners/On-board diagnostics (OBD2) is an automotive term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers. Early versions of OBD would simply illuminate a malfunction indicator light or “idiot light” if a problem was detected but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow a person to rapidly identify and remedy malfunctions within the vehicle.

Taking the car to a professional mechanic or repair shop isn’t, only expensive but also requires time. Unfortunately, there comes a time when the car starts behaving erratically, and the check engine light comes on. The ABS or airbag light may also light up, and this will make you a bit uncomfortable to drive the car since you don’t know how severe the problem is and would rather not put your life and that of others at risk. Instead of struggling with a malfunctioning car or not feeling confident or worrying too much about the warning signs, why don’t you invest in an OBD II scanner? It will help you to instantly diagnose the issues from anywhere even if you lack experience. After looking at the products being offered in the market, we concluded that the following are the best OBD2 scanners.

Benefits Of OBD2 Scanners

The need for a scanner is inevitable for different applications. It may seem simple by the term scanner, but actually there are lots of variants when it comes to the choice of scanners. The present discussion is focused on the benefits of OBD2 scanners. The coding nature of the OBD 2 scanners is regarded to have conveyed a lot of modification to the business years. A few years back, it was mentioned to note that motorists had to face through the hassles of having to take their car to the neighboring garage notwithstanding the fact that in the end, there would be much time consumed while trying to solve the minor faults.

The way in which the OBD 2 scanners of the present age are capable of identifying the specific areas where the fault is present is unique. The corresponding benefits provided by such scanners have simplified the life of the mechanics and motorists. Take a look at the benefits of these scanners:


Taking into account the repair cost in the present era of manual mechanical fault detection, there are many benefits of using the OBD2 scanners. The time, level of precision, and information are worth considering. These types of scanners provide the location of the specific fault area and also give the possible solution on the fault. Therefore, the repair costs become cost-effective. It is found that the relative costs of the scanners are usually low while compared to those few years back. They typically cost lesser along with broad coverage which makes them quite user-friendly.


There are lots of OBD2 scanners that are equipped with the potential to update on the wireless media. The same enables the scanners to last longer and ultimately facilitating the users in a better way. While choosing these scanners, durability is the prime factor to focus on.

Automatic Operation

The majority of the present-day scanners available on the market are essentially doing it yourself devices. They are found to be user-friendly to the car owner with the use of appropriate user repair guides. Moreover, they provoke the driver to perform the overall fault repair without anyone’s assistance or without visiting the mechanic.


The capability of the scanner to code on different car models is essential to take into account. With different protocols and millions of codes encompassed by most of them, it is necessary to check compatibility. They are identified to serve the user with tons of options. Moreover, broad compatibility enables such devices to work on different models and thus making them affordable.

Data Tracking

The contemporary models of modern scanners can offer rich information regarding your car. But if you are not a mechanic, it can be hard to comprehend what it means. Therefore, you should pick a unit that depicts clear data, charts, and easy-to-read graphs. Furthermore, you must be able to supervise this data over time in order that you could see any modifications as they happen and utilize that information to your benefit.

Live Scanning

The advancement that contemporary scanners have is that they enable the user to check their car’s performance. Because the onboard computers are much more advanced compared to what they were in 1996, it is easy to monitor the entire system of your vehicle at once. It is known that live scanning is an efficient tool since it can assist you in tracking the operation of your vehicle over time. Moreover, it allows you to identify any potential concerns prior they turn into an issue.

Accurate Self-diagnosis

By simply plugging an OBD2 scanner unit inside your system, you will receive an exceptional viewpoint on the health of your vehicle. For example, if you could notice a check engine warning light, then connecting an OBD2 scanner can pinpoint a particular DTC. Thus, it enables you to identify the root cause precisely. In case you are making use of an OBD2 Bluetooth adapter then you will be able to view all this information on your smartphone.

There is no doubt that time is money and so this diagnosis will help. The precise self-diagnosis can save both, particularly if it denotes a simple fix. To understand this, for example, a blocked filter can be effortlessly repaired at your home; thus, it avoids expensive hours in the garage or time in the absence of your vehicle. Considering the hefty fee for an OBD2 tool while using at a service station, it generally makes the fiscal sense to invest in your own. It is possible to save many dollars spent on future repairs or on maintenance costs.

Maybe your vehicle is connecting to your device, but you are experiencing an Error during Operation.

If this is your case, maybe your device is freezing or experiencing slow running and reading times.

To combat this problem, try these steps:

  • Reset your scan tool.
  • Turn off your ignition, wait for about ten seconds, and try again.

On the other hand, you may have a more serious problem if your Scan Tool Doesn’t Turn On.
