What to consider before buying the Best Automotive Diagnostic Scanner?

The number of different, easy-to-purchase car diagnostic tools increases monthly. The most popular of the OBD2 scanners is the one designed for the average car owner, so the market offer for these tools is quite high at prices below $100.

For professional needs or wanting to go beyond just reviewing and modifying error codes, it is recommended that you purchase medium to high price diagnostic tools so that you can perform more interesting functions and achieve substantial fixes on the cart.

We know exactly what to look for as we have used over 50 different scanners on a variety of cars. Below we will show you the most important aspects that must be taken into account to learn from the world of the best diagnostic tools.

Types of Diagnostic Scan Tools

Scanners come in a wide range of shapes from laptops with many cables to a tablet form, ussualy the cheapest tools are the simplest and smallest forms as they do not need room to store processors or hard drives.

The best scan tool for mechanics are the mid-range to premium diagnostic tools, which they need to include service light and engine management light removal, since most customers will expect this after having a service.

The real difference which decides what type of scan tool is more suitable is the port type. As we said earlier, most of modern cars will have an OBD2 port and that is why we listed all the devices above. However, cars before 1998 are often referred to as an OBD1.

The term OBD means On Board Diagnostics and the # refers to the generation it belongs (1st or 2nd). The OBD1 scan tools are not universal and are usually specific to each car and provide completely different codes, and OBD2 have a huge improvement upon the first generation.

The research of an issue becomes very easy since OBD2 cars can connect to a huge range of devices and provide throught them standardized error codes. From OBD2 the amount of information you can get using a obd2 scanner tool is much higher than OBD1 tools, this is why is a great improvement.

obd2 scanner

A car mechanic should own both OBD1 and OBD2 scanners because it is very possible to have a classic car customer one day and a modern car another. All OBD2 ports are the same and there are no different variations of the port.

So, if you are going to be using this type of tool as part of your everyday job, it makes sense to get the best diagnostic scanner you can buy.

OBD2 Specific Diagnostic Readers

All the automotive diagnostics scanners that were shown in this article are tools that can be used with many different car manufacturers, so they will attract a wider audience. But there are certain manufacturers that offer their own specific scanners.

For example, the VAG Group (Volkswagen, Audi, Skoda, Seat and more) can use the Super VAG K + CAN Plus 2.0 as a diagnostic tool, with which additional features can be programmed using this tool.

However, almost always the user will have to pay a premium for a diagnostic tool that is specific to their car, as is the case with the Mercedes Star Machine that can perform a lot of functions, but is not the most user friendly device because it has many cables that connect to each other.

A factor that must be taken into account, all car specific diagnostic tools have the same problem, you can only use it on cars from the same brand. This is where the need and solution to this problem comes from, as the best auto scanners described above can be used in hundreds of different cars.

It is obvious that when investing in a diagnostic scanner, it is best to get a scanner that works for a range of manufacturers.

Automotive Diagnostic Tools Easy To Use

Not all of the car diagnostic systems are the same, and choosing the best one can be difficult without knowing what to look for.

The questions that need to be aslked are: is it easy to read or to understand the information that is being displayed? is the interface compatible with what you need?. The answer will determine what type of information will be able to be seen and observed on the unit. The first thing that needs to be ensured is that the diagnostic tool has lots of documentation.

The worst thing that could happen is to adquire a scanner tool and not knowing how to use it. All the divices listed above are simple to use, but the best professional automotive diagnostic scanner may need a few hours of research and learning to become an expert with all the functions.

One aspect that should be avoided are the error code readers that do not provide novice users with additional information, since there may be stored codes that are serious or harmless and the tool should provide this sort of information. It is the same with the graphs and different outputs, this should be stated with different colors if it goes below a certain level.

Compatibility of Diagnostic Tools

It is not possible to plug an OBD2 connector into an OBD1 port and vice versa. But, there are many scanner tools that are capable of working for both ports with connectors for each type. All OBD2 ports are standardized and when a car states that it has an OBD2, your scanners connector will fit.

Car specific diagnostic tools that were mentioned above (MB Star and VAG Super K+) are OBD2 connectors but they will not be able to be used in other brands.

Actually, many OBD2 Scanner manufacturers will provide enhanced diagnostics and functions for certain car brands. It is always worth paying a little more for a tool that will provide enhanced functions if you just have a car.<

For example, if there are people that do not own a smartphone that can download applications, devices such as the BlueDriver will not work and it is obviously better going for an alternative.

Most Common Error Codes From Diagnostic Scan Tools

Here we present a list of codes that can be seen while working with an OBD2 scanner.

  • J1850 PWM. Used in 1996 vehicle models that are Scion, Lexus, Isuzu, and Toyota. Also include information for 1996 and 1993 GM modeled cars. This connector has 2-4-5-10-16 pins.
