Types of OBD2 Scanners

Handheld

These have basic features and are ideal if you just want a simple scanner. They’re simple to use and make it easy to read and erase codes. These are best used for performing simple repairs and to provide information for mechanics. If you’ve got a common vehicle with basic needs, this will do fine.

Professional

These scanners have more advanced features and offer programming options for advanced users. Compared to a basic handheld they have a lot of features so you can solve problems in-depth. Professional quality scanners also have wider compatibility, essential if you’ve driving a rare car. While they have a lot of information they’re also easier to use.

Mobile

These devices often come with a mobile app, and they retrieve data from diagnostics on your car. With the companion app you’ll be able to view the data. Most of these apps are downloadable to your smartphone, tablet or computer.

This is just a general classification of the common types of OBS2 scanners: new devices are always being developed and the difference between handheld, professional and mobile gets blurred all the time.

The Advantages of an OBD2 Scanner

If you don’t have one of these scanners yet it’s about time you did because they provide a lot of advantages.

  • Comprehensive Scanning: onboard diagnostic scanners provide information on fixes for all the major components of your car including the ignition system, auto transmission, fuel injection and more.
  • Confidence: with the best OBS2 scanner you can feel confident that if there is a problem you’ll know where to find the fix. If the engine makes a pinging sound or the engine check light goes on, you just turn to the scanner and find out what’s wrong.
  • The information you get from the scanner helps if you’re the DIY type or just want to give the mechanic as much information about the car problem as possible. You can also use the codes to verify what the mechanic is saying.

Tips for Buying an OBD2 Scanner

If you’ve never purchased one of these devices before, consider the following to help you make the best purchase.

Compatibility

This is the first thing you should look at, because if the scanner isn’t compatible with your car then there’s no point at all. Fortunately this won’t be a major issue because modern OBS2 scanners are compatible with a wide array of vehicles. If you’ve got a rare make and model, contact the manufacturer first.

Unlike OBD1, OBD2 has wider compatibility so you can scan vehicles without any issues. However there are some diagnostic scans which work only with specific models so you have to consider that as well.

Updated

There should be Wi-Fi or Internet connectivity to make software updating easier. Basic OBS2 scanners may not have this feature but a growing number do, and it’s something you should really consider.

ABS Scan Tool

An ABS scan tool provides detailed information about the codes and allows you to view data in real time, read and print.

Full Protocol Support

A good OBS2 scanner should support the 5 protocols so you don’t have to worry about compatibility. Read the scanner’s description first and make sure there is support for all five so even if you get a new car support is guaranteed.

Quality Screen

It’s easier to view the data if the scanner comes with a backlit LCD screen. The more data the scanner provides, the larger and clearer the screen has to be.

Brand

Just as you wouldn’t settle for a cheap oil filter or car wax, the same rule applies to diagnostic scanners. A little bit of research will give you an idea which brands are preferred by buyers. This doesn’t mean new names are untrustworthy. However with known quantities you’ll be assured of good customer service and warranty.

Durability

Rough driving conditions, the weather and extended use can take its toll on scanners. This is another reason to go with known brands because their scanners are made from durable materials and longer charge time with well equipped batter.

Accessories

A code translation manual helps, though in most cases it is probably included already. A hard disk provides you with extra storage, and other useful accessories include a voltage regulator, adapter and mini printer. Not all of these are necessary so just pick the ones you really need.

How to Install an OBD2 Scanner

The information below is a general guideline, but you should refer to the manual for more detailed instructions.

Start by looking for the connector port in your car’s compartment and connect the OBS2 code reader. Turn the key on but don’t start the engine yet. The scan tool should prompt you for information about your vehicle, i.e. the engine type, make, model and vehicle VIN number.

Additional instructions may appear onscreen, so just provide the information being requested. Again the process may vary from scanner to scanner; with others you just plug it in and the device automatically senses the vehicle’s make and model.

How to Use an OBD2 Scanner

Once the device is installed you can access the codes. The scanner will provide a description, but you can also refer to your vehicle manual for information. With quality OBS2 scan tools this won’t be necessary as it will display the code, what it means and the repair.

Difference between OBD1 and OBD2 Scanners

The biggest difference is OBS2 is more efficient. Some scanners have OBD1 and OBS2 compatibility, but if it only supports OBS2 it’s not going to be an issue.

Installation: OBD1 scanners are installed under the dash so it’s hard to get to the port. OBD2 devices are set in the driver’s compartment so it’s easier to set up. OBD2 is also more reliable, has better definitions and uses more advanced technology. OBD1 was developed to just read the codes and nothing more, whereas OBD2 is capable of fixing more problems.

OBD2 is especially good when it comes to detecting engine problem. OIBD1 can read some engine issues but only to an extent, while OBS2 has more to offer in terms of solutions. The computer chip on OBS2 devices are also updated regularly while those on OBD1 had to be replaced.

Conclusion

Just like with any automotive product, you have to go through all your options to find the best OBS2 scanner. Even if your car is in good condition, it pays to invest in one of these as it could save you a lot of trouble later on.
