An OBD2 diagnostic scanner is a vital tool that enables you to check on your car performance in real time. With this type of scanner, you can save thousands of dollars when you use it to assess the vehicle's power and control systems. If you are tired of spending money every time a mechanic diagnoses your car, then you should get yourself an OBD2 Scanner for home use. These devices will give you the reason behind every sensor light, they not only tell there is a problem but indicate what the problem is and possible solution. Some of the best OBD2 scanners have advanced features that can clear error codes without going to a car shop.

To get the best OBD2 scanner that suits your needs, you will need to look at the following pointers.


What are The Benefits of an OBD2 Scanner

Before we get into the details highlighting the benefits of an OBD2 Scanner, we need to know what it is.

An On-Board Diagnostic (ODB) scanner is used to store the logs of your daily car operations up to the last second. It records the temperature, fuel readings, location logs, speed, and direction, and can also be used to check for emission levels. It is a handheld device with ports that can be plugged into your car and downloads the latest information on the car performance. Some countries have a regulation stipulating that all vehicles must have an OBD2 scanner unit installed.

All problems that are found in your car are relayed in error codes that can be interpreted based on a reference manual that contains a better explanation of the error codes. The advantage of having an OBD2 scanner unit is the ease in which you can locate errors and take appropriate action before a major damage is caused. You can simply walk into any car, plug in the scanner and get all the information you need about the car performance. These scanners can also be used to check if your vehicle is compliant with any set rules and regulations.

Contrasting the old system of car error alert system with these OBD2 Scanners, where different light sensors are used to tell of a possible problem without pinpoint information, any OBD2 scanner unit will download the various sensor data and give you the exact problem diagnosis.

Owning one will save you money especially if the error identified is something you can fix yourself without having to visit the service shop. For instance, you do not need to pay someone to tell you of the need to replace your tires if the OBD2 scanner can tell all this in a matter of minutes.

What Varieties of OBD2 Scanners Do we Have in The Market

The good thing about standardization is that any OBD2 scanner unit of your choice can work on any vehicle model. There are some scanners that are able to download and show the exact problem on the go, while others in the market will download the same information and relay the diagnostics in standard error codes that need the eye of an expert to understand, or you may need to look up for an error database definitions to get the exact problem. Advanced models of the OBD2 scanners can be connected to a PC to further analyze diagnostic data or get software and firmware upgrades to conform to the latest standards.

If you are the vehicle diagnostic and tuning business you may need a scanner that relays information in real time so that you make adjustments on the go without the need for further analysis.

What Makes One Scanner Differ From the Other

Diagnostic Features shown make the difference. One set of OBD2 scanners will only give the error information in form of codes while there are some that give detailed information about the problem and possible solution.

Some scanners can get their power from the car the moment it is attached, while other OBD2 scanners have a battery installed on them which is appropriate for offline use.

Connectivity aspect of an OBD2 scanner unit also matters. Some can connect to PC to further probe the data collected or to give you a better view during analysis. This connectivity may also allow data storage for future reference.

Why Use OBD2 Scanners

You can use any OBD2 scanner for many tasks that may fall in the DIY category. It is possible to check and clear error signals without the need to visit a garage. You can also use it to monitor fuel usage and monitor routes if you are a fleet owner. Fleer owners can also have the ability to remotely monitor speed, idling times, and driving habits of a particular vehicle.

Some OBD2 scanners have navigation systems that can be used to detect poor driving. Some are equipped to disable or lock out telephone communication while the vehicle is in motion.

What to Look For Before Purchasing an OBD2 Scanner

  • Look for an OBD2 Scanner with a good support sales team and proper documentation which guarantees reliable performance.
  • Before buying one make sure that your vehicle year of manufacture does not lock you out on the type of OBD2 scanner that you can use.
  • Look out for scanners models can only work within a given geographical area.
  • Get to know the power consumption of every scanner unit, some have been reported to drain car batteries if left connected for long.
  • Confirm if what you are looking for requires any specific software or hardware for it to work well.
  • Is it easy to set up and can the OBD2 scanner be used right after powering it on.
  • Look for one with a comprehensive repair report analysis.
  • How compatible is the scanner in relation to Apple and Android devices.
  • How do you prefer the scanner you looking for to relay diagnostic information? Some can do it via a laptop screen while others can relay the information directly via Bluetooth to compatible devices.
  • Look at the product review pages, chances are that if positive reviews outweigh the negative ones you more likely to get the best OBD2 Scanner.
  • The price tag: Some scanners may be costly because of the software complexity and connectivity options involved. I would suggest opting for OBD2 scanners that are moderately priced that does all the functions that you are looking for.
