What Is An OBD Scanner?

An OBD scanner tells the car owner or the mechanic regarding the status of the car’s subsystems and if something is wrong with the car. This might include MIL (malfunction indicator light), trouble codes, and other malfunctions with the car.

There are built-in sensors in these scanners that help detect abnormalities in the car such as issues with transmission, engine oil, spark plugs, catalytic converter, airbags, SRS and so on.

Why Do I Need An OBD Scanner?

There are many perks of getting an OBD scanner for your car, such as:

DIY: OBD scanners are like your personal automatic diagnostic assistants. Once connected, they diagnose your car for problems and tell you where and what the problem is.

These mostly have dedicated apps and are run on smartphones thanks to Bluetooth connectivity. However, you may get some corded options, too.

This way, you get to learn more about your car and fix car issues yourself.

Save Money: An OBD scanner is very easy to use and with it, you can learn what is wrong with your car.

Even if you’re not a professional at using OBD scanners and have little information about how a car works, you can still benefit from it.

The INFOGRAPHIC below is a simple guide that tells you things to consider when picking an OBDII scanner.

INFOGRAPHIC: How To Choose The Best Car Diagnostic Scanner?

Should I Take Corded Or Bluetooth OBD2 Scanner?

Corded scanners are fast and more reliable because they do not require any phone connectivity. In fact, they have their own interface which is quite easy to use.

Corded scanners are often disliked by users because the cord is frustrating and hard to handle. If you pick a corded one then go for an option that has a long cord so you can keep it in your lap.

On the other hand, Bluetooth scanners are much more convenient as they operate wirelessly, from a phone.

Make sure to pick a Bluetooth scanner that supports the platform (Android, Windows or iOS) that your phone uses.

It’s usually a personal decision. There isn’t much difference in price and performance.

Which Is Better?

It depends upon the scanner’s ability to remain connected for longer and doesn’t lose connection.

Moreover, you can also opt for a Bluetooth scanner that supports all the mobile platforms including Android, Windows, and iPhone.

Let’s have a look at the differences in detail through this chart.

SpeedNot be as fast as the corded scanners because they need to establish a Bluetooth connection first, which can be weaker and it might affect the speed.Fast and reliable because they have their own interface and do not require any external connectivity.
Price RangeMost Bluetooth OBD2 Scanners are cheap (Under $100).Available in a wide range of price depending on what features they are providing.

Which Protocol Is Supported By My Vehicle?

To find out the suitable protocol for your vehicle, follow these steps:

  1. Look for the OBD port under the glove department, dashboard, below the steering column or a few feet away from the car’s centerline.
  2. The OBD port will be located in one of the above locations.
  3. Now, look at the DLC pinout, specifically at the inner teeth that are on the serial bus. Follow these steps to know the protocol supported by your vehicle:
  • J1850 PWM: If the connector has pin 2 and pin 10, the protocol is J1850 PWM. The connector should also have metallic contacts inside pins 2, 4, 5, 10, and 16.
  • J1850 VPW: Pin 2 is a must. The connector must have material contacts inside pins 2, 4, 5, and 16. However, pin 10 should not be there.
  • ISO9141 and 14230 (KWP2000): PIN 7 is a must while pin 15 is optional. Metallic contacts inside the connector should consist of pins 4, 5, 7, 15, and 16.
  • ISO 15765 (CAN): Pins 6 and 14 should be there, while the metallic contacts should have pins 4, 5, 6, 14 and 16.
Look closely at the alignment of the connector and you’ll figure out the protocol supported by your car.

Other Things To Consider Before Buying An Obd2 Scanner

It is important that you check a few more things mentioned below before buying an obd2 scanner. These include the price range, update policies of apps etc.

Price Range

There are no rules about the price ranges of the scanners. But generally, code readers and DIY scanners are cheaper than professional automotive diagnostic tools.

If you are looking for a basic code reader then it might cost you between $10 to $100. As for DIY scanners, they are a bit more than basic code readers and can be bought between $50 to $250. Lastly, professional automotive diagnostic scanners are between $250 to $3000+.


It is essential to check the update policy of the scanner before buying it. Some might come with a 1-year warranty and some can offer more than that and cover free updates for 2-3 years.

Many obd2 scanners such as Autel AL319 offer free updates for a year. Other than that, OBDLink MX and LX come with lifetime free updates for software as well.

However, there are some scan tools that do not offer free updates and you must pay chargers which can be as high as $40.

Updates are necessary because they help you tackle new problems in your car.


Most of the obd2 scanners offer a maximum of 1 or 2 years of warranty. However, the best warranty deal is offered by OBDLINK MX and LX.

Both come with a 3-year warranty for manufacturing faults.

After Sale Service

It is important to buy a scan tool from a brand that values its customers. This can be determined by reading online reviews from the internet.

Autel is one of the best when it comes to customer care.

Tech Support

The type of tech support you’ll be needing involves quick solutions to problems. There should be a representative available online to help you walk through problems and to answer all the queries that you have.

Refund Policy

Not many companies will refund money unless a defective product was sent. You can confirm the refund policy directly from the brand by visiting their website and getting online support.

    I have a Mitsubishi Lancer 2007 1.3cc VIN Code JMYSRCS1A7U719836.
    Can you confirm that your device CRP 123X431 Creader is compatible with my Mitsubishi Lancer car.
    FYI: l bought 2 devices AL519 and ML619 both made by Autel Scanners. As per Manual it can read all kind car. But it can not read to my car .
    I tested my car in big workshop using Lance device and it can read my car perfectly
    best regards

  2. Hi,
    Two things, please.
    1. Dashcommand users are reporting a lack of support. Any feedback?
    2. Which of the hand-held tuners, like FOXWELL NT510, is best for BMW-specific codes for under $100?


  3. I got this web site from my friend who informed me concerning
    this web site and now this time I am browsing this web page
    and reading very informative posts at this time.
