What OBD 2 Scanner Should I Buy?
Diagnostic scanners are differentiated by the range of codes they are capable of detecting. The simplest ones are known as code readers.
They have the basic features and can clear codes, but not much else. However, they are certainly cheaper. They won’t display more than engine data or PCM.
The more sophisticated OBD 2 scanners come with multiple unique features. Before buying, you need to know whether your scanner will work on European or Asian cars.
If you have a US-based car, most scanners will be suitable for you. The more expensive ones are suitable for more than one kind of vehicle.
The best car diagnostic tool will come with alerts for problems concerning monitoring of the tire pressure, anti-lock brakes, and more which includes about 75 codes which are installed in most vehicles.

What Is an OBD 2?
OBD 2 scanners or Onboard Diagnostic Scanners are connected to the onboard computer of the car for diagnosing codes and reporting.
While OBD 1 scanner varies according to the manufacturer, OBD 2 scanners use similar designations for codes, connectors, and protocols for communication.
The simplest code readers, while providing the basic code reading and clearing mechanisms do not offer further information on codes that are manufacturer specific. It also does not offer access to any other data.
Scanners, on the other hand, offer access to both recorded and live data. It also offers manufacturer specific codes. They can also read soft codes which are codes which haven’t yet turned on the check engine light.
It has more access to information as well. The data is collected from all the sensors and fed to the onboard computer.
All OBD II scanners use one connector called SAE J1962. The basic scanners can be plugged into the diagnostic connector for OBD II in the vehicle.
The best car diagnostic tools come with modules or keys meant to augment the connector for interaction with the controls or information that are OEM specific.
What Is ELM327?

It usually supports many protocols of ISO and SAE.
It can connect with any vehicle with an OBD-II connection. While not exactly the same as the Hayes command yet, its commands are very similar.
While you can use the ELM327 for diagnostic tests, you have to access other software and hardware. They will also offer you the trouble codes and you can read the PIDs as well.
The communication system is bi-directional. With this, you can clear the codes that you have already accessed.
The ones with a Wi-Fi connection are usually more expensive. But at the same time, they connect with more devices than those with a Bluetooth connection. But the ELM327 devices that are connected through USB have the widest compatibility.

They are cheaper than the ones with Wi-Fi connections. However, with PC or Android, you can connect any one of these.
What Is a DTC Code on a Car?
DTC is short for Diagnostic Trouble Codes. The computer based engine of your car is able to self-detect any problems in your vehicle that affects its emissions and performance to an extent.
This can also be applied to the anti-lock system and the onboard system.
When a problem has been detected, the computer will retain the DTC in its memory. Then the check-engine lights are activated.
Some vehicles can turn on their diagnostic modes by grounding those terminals which are available on the diagnostic connector.
