Do I Really Need An OBD2 Scanner With Advanced Functions?

If you do not have an in-depth knowledge of how a car works and how to solve complex problems then an automotive diagnostic tool with advanced features isn’t necessary.

Most of the codes mentioned will be out of your grasp and eventually, you’ll need a mechanic’s help.

However, if you are a professional or a mechanic, take one.

Infographic: How to choose the Best OBD2 Scanner?

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

	Bluetooth Scanners	Corded Scanners
Best Scanner	BlueDriver Bluetooth Professional OBDII Scan Tool	Autel AL619 Corded OBD2 ABS SRS Scan Tools
Mobility	Better mobility because you can control the scanner from the backseat of the car, from outside the car etc.	Limited mobility. Corded scanners offer mobility as much as the cord length.
Speed	Not 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 Range	Most Bluetooth OBD2 Scanners are cheap (Under $100).	Available in a wide range of price depending on what features they are providing.
Apps	Require an app to work.	Do not require any external software or app to run.

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.

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+.

Update

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.

Warranty

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.
