The Best OBD2 Scanner for cars

What are OBD2 scanners and how do they work?

The first thing I want to convey is to understand in detail what a scanner is, for this I leave you the following definition.

OBD2 scanners are electronic devices with which we can monitor the different systems of a car and obtain the active faults in our car.

Its operation is usually very simple, since it is only necessary to connect them to the OBD port of our car and via Bluetooth or Wifi (depending on the model) we can view the results from our cell phone, computer, tablet (compatible) or on the same screen of the scanner.

One of the main reasons why you should have a scanner at home, is that you will be able to get the fault codes from your car.

Yes, with this device you will be able to diagnose the different systems of the car and reset them when you have corrected them, but the most important thing is what, you will be able to identify serious failures related to the sensors, such as:

1.- The temperature sensor
2.- Oxygen sensor
3.- Brake sensor
4.- Electrical sensor

These are the top 10 automotive obd2 scanners for your car

I’ve made a list of the best scanners I found on Amazon , which have excellent features and benefits, also are highly requested by professionals and hundreds of amateurs, I leave you the list with its main features, advantages and disadvantages of each one.

Should I buy a scanner?

If you still have doubts about whether or not it is a good option to buy this type of device, let me ask you something How did your last check go? With a scanner you will be able to make the diagnosis yourself and have a better understanding of what is going on in your vehicle before going to the check.

Remember that it is not a game that your car is in optimal condition, your safety and that of your loved ones is priceless, and with a team like this, you can check your car before each trip.

Now, if you are a mechanic or have your own shop, this device cannot be missing from your toolbox, since it will save you a lot of time to diagnose a failure and give you an idea of where to start working.

What parameters do OBD2 scanners read?

The great advantage of these devices is that they allow us to obtain a wide range of extremely important parameters of the OBD system without worrying about whether we know for sure what OBD2 is and how it works, this is where the importance of the scanners lies since for users who do not know much about mechanics they are poured into a perfect tool.

One of the main parameters they read are the fault codes or DTC which indicate exactly what section or system is failing in our car, in addition, most of the scanners provide extra information that helps us better understand the fault and give us an idea of how to solve it, here I leave a list of the rest of parameters that are also very important:

RPM – Engine Revolutions per Minute
Vehicle speed
Gasoline consumption
Coolant temperature
Gasoline system status
Suction tube pressure
Reset active fault codes
Oxygen sensor voltage
Airflow range
Oxygen sensors

With a scanner you can monitor the status of your vehicle in a very simple way, you can even validate the OBD2 driving cycle in a very easy way, there are several manufacturers on the market that provide mobile applications with which you can monitor in real time the systems of your car and know if any of them is alerted by a failure, This is where the importance of these devices lies, since most manufacturers have a database with the failure codes thrown by the vehicles, giving you very detailed information on each failure. With this you can go to a specialized mechanic, indicating specifically what is wrong with your vehicle, saving you a lot of time and money.

Is my car compatible with OBD2?

You must be careful before acquiring an OBD2 scanner, first validate if your car is compatible, since from 2006 it became mandatory the OBD2 standard in Mexico, 1996 in the United States, 2009 Argentina, 2007 Brazil, etc., so if your vehicle is a model older than 2006 surely has integrated the OBDII protocol in Mexico.

Vehicles that have OBD2 implemented commonly have an SAE J1962 diagnostic connector within one meter of the driver’s position, in most cases you will find the connector at the bottom of the dashboard or behind the dashboard, however, consult the manufacturer’s manual for the exact location.

Many older vehicles have a similar connector but do not comply with the OBD2 standard, therefore, even if they have a J1962 connector does not mean that complies with the OBD2 protocol and you can not make use of scanners because they fail to read or simply do not throw data.

How to choose the best scanner?

No doubt all scanners are very good, however, you should consider some points in order to choose the best scanner for you:

  • Compatibility with your car, you must know exactly if your car has fully implemented the OBD2 protocol, check the manual to be sure.
  • Budget, if the intention is to use it only in your car maybe buying the cheapest one is an excellent option since they all comply with the reading of the OBD2 protocol and basic monitoring of the systems.
  • If you are a professional in our store we will be uploading more sophisticated products and their review.
  • If you are not familiar with OBD technology, please review our summaries to better understand these types of devices and become familiar with the terms used.

What are the advantages of OBD scanners?

The biggest advantage they provide is that you will be able to diagnose your vehicle yourself just like a professional would and you will be ready to have your car checked.

Another advantage is its easy installation, just connect it to the OBD port and start the diagnosis from your cell phone or from the screen of the device itself.

We have seen that the scanners read an infinite number of parameters in our vehicles, now it’s time to summarize and define some of the OBD2 test modes:

OBD2 Testing Modes

We have seen that the scanners read an infinite number of parameters in our vehicles, now it is time to summarize and define some of the OBD2 test modes:

Test Mode 1 OBD2

PID parameter identification, which is the access to real time data of analog or digital values in and out of the ECU, is also known as data flow indicating the engine temperature.

Test Mode 2 OBD2

Access to frozen data tables, the ECU takes the values related to the emitters, at the exact moment a failure occurs.

Test Mode 3 OBD2

Read the ECU memory to obtain all stored fault codes (DTC – Data Trouble Dode).

Test Mode 4 OBD2

Deleting or resetting the fault codes stored in the PCM including the DTCs and the frozen data box.

Test Mode 5 OBD2

Results of the tests carried out on the oxygen sensors to corroborate their operation and the efficiency of the catalytic sensor.

Test Mode 6 OBD2

You get the results of all onboard tests.

Test Mode 7 OBD2

Reading the memory of the ECU to obtain the pending DTCs.

Test Mode 8 OBD2

Actuator test, allows to deactivate or activate the actuators of the fuel pumps, idle valve, etc.

These are the best-selling scanners at the best prices

Here I leave you these other scanners that have turned out to be very interesting and in high demand in online stores.
