4. Buyer’s Guide: How to Choose the Right OBD2 Scanner

Learn how to choose the right OBD2 scanner for your needs, considering factors like code reading, diagnostics, live data, ease of use, and connection type.

4.1. Read & Clear Codes

The most basic function of an OBD2 scanner is to read and clear trouble codes that cause check engine lights. A trouble code is produced by the onboard computer system when it senses a status that’s out of normal parameters, which can exist within the engine, transmission, emissions, or other systems.

Clearing a code deletes it from the system and turns off the check engine light. If the problem that caused the code is not fixed, the vehicle will produce the code again and turn the check engine light back on. You can clear a code to verify that it is a recurring problem by waiting for it to come back or after a fix is attempted.

4.2. Foundation: How to Read an Error Code

Codes produced are five characters long and can be broken down simply. The first character of the code represents the system related to the problem:

• B: Body
• C: Chassis
• P: Powertrain
• U: Undefined

The second character indicates whether the code is generic or enhanced:

• 0: Generic
• 1: Enhanced

The third character identifies the sub-system that the code pertains to:

• 1: Emission management (air or fuel)
• 2: Injector circuit (air or fuel)
• 3: Misfire or ignition
• 4: Emission control
• 5: Idle control and vehicle speed
• 6: Output circuit and computer
• 7: Transmission
• 8: Transmission
• 9: SAE Reserved
• 0: SAE Reserved

The fourth and fifth characters are variable and relate to specific problems.

4.3. Code Reading Interface

While all the scanners in our guide can connect to the vehicle and produce the five-character trouble code, some make it easier to read the codes and read more vehicle-specific codes. The Motopower MP69033 doesn’t have many features, so it has an uncomplicated menu that is very self-explanatory for reading and clearing basic codes.

The Bosch 1300 OBD takes more time to read codes as it asks a few questions before reading them but can read airbag and ABS codes.

Bluetooth code readers use a phone-based app to read the codes, which is quicker and delivers more information. Each Bluetooth app walks you through connecting to your vehicle and reading error codes.

The Ancel BD31 can read both airbag and anti-lock braking system (ABS) codes. The Bluedriver Pro can read airbag, tire-pressure monitoring system (TPMS), and ABS codes. The OBDLINK MX+ and the Topdon TopScan OBD2 Bluetooth Scanner can read ABS, airbag, TPMS codes plus additional GM and Ford codes and parameters.

4.4. Diagnostics

The first step when using an OBD2 scanner is to read the code, provided in a basic five-character format. When a scanner provides its reading, it delivers a basic description associated with that code. The Motopower MP69033 only displays the code and its foundational descriptions.

For example, P0113 identifies the Intake Air Temperature Sensor 1 Circuit High. After you have the code, you can diagnose the problem that caused the code. Many scanners in our guide go a step above reading codes and provide high-quality diagnostics.

The Bosch 1300 OBD provides the same information on its screen as the Motopower MP69033 but has an internal library of 26 million possible fixes for different error codes. You can type in the specific error code to find possible fixes.

Bluetooth-compliant OBD2 scanners connect to the internet, opening up a library of information for understanding codes. They include a link to the internet to search the specific code to find fixes, but this requires cell service. The Bosch 1300 OBD has its diagnostics saved internally in its computer. The Ancel BD31 stands out, offering six possible faults per error, plus a link to view more information via Google for every faulty code.

4.5. Live Data & Real-Time Monitoring

OBD2 scanners read codes and show you real-time data about your vehicle. Each trouble code is associated with a sensor on your vehicle, and you can use a scanner to view the live data from any of the sensors.

Certain scanners let you view only one set of sensor data at a time, while others monitor and display lists of multiple sensors at once. Some code readers chart these data sets with a graph or numerically, while others put them into an easily readable display.

The OBDLINK MX+ stands out, using a heads-up display similar to a dashboard gauge to show 13 specific and comprehensible parameters. You can monitor any of the vehicle’s sensors on a different screen and archive the data for all the vehicle’s sensors. It collects data from hundreds of vehicle sensors and logs trip data, including GPS, trip distance, and fuel economy.

The Topdon TopScan OBDII Bluetooth Scanner can adjust the air fuel mixture and perform compression testing on each cylinder.

4.6. Ease of Use

Modern scanners make it easy for any level of automotive enthusiast to use and understand trouble codes. Each scanner has step-by-step instructions and prompts to help walk you through connecting and scanning your vehicle.

Bluetooth-compatible scanners shine in terms of ease of use. To read error codes, you need to download the corresponding app for a compatible phone or tablet, plug the scanner into the OBD2 port, and connect via Bluetooth. The user interface is more vivid and comprehensive compared to traditional wired scanners.

The Bluedriver Pro and its corresponding app are the easiest to operate, with a simple menu and clear instructions for every step of the process.

4.7. Connection

Each scanner connects to the vehicle’s OBD2 port via an OBD2 plug, either using a wire from the port to the scanner or a Bluetooth connection to a cell phone or tablet.

4.8. Wired

Wired OBD2 scanners are more common and are the original design. The brain of the scanner is contained within its own shell. They come with a screen that displays information, and the face buttons control the device.

They don’t require additional batteries or accessories and can even store information offline, like the 26 million code fixes in the Bosch 1300 OBD. Using the scanner means you need to be physically close to the OBD2 port, usually sitting in the front seat of the vehicle due to the wire’s constraints. They take up more space compared to Bluetooth counterparts.

4.9. Bluetooth

Bluetooth scanners are very small. They plug into the vehicle’s OBD2 port but don’t use any wires. Instead of an included screen and a wire, this device uses Bluetooth to connect to a phone or tablet. The brain behind the system is an app that needs to be installed onto your phone or device.

Using a phone means you’ll have a much larger and crisper screen, and the user interface is easier to use. These gadgets take up less space when not in use and can even be left plugged into the OBD2 port when powered down.

However, they need a fully charged phone or tablet with the app installed and may not display some information if you’re out of cell phone coverage or lacking a Wi-Fi connection.

What does an OBD2 scanner do?

OBD stands for onboard diagnostics, a standard protocol across most light-duty vehicles to retrieve vehicle diagnostic information. This scanner talks to your vehicle’s computer, reading and clearing check engine lights or codes. Certain ones can apply diagnostics to show possible causes and fixes, measure driving behavior, or show real-time data from the vehicle.

Do OBD2 scanners work on all vehicles?

In 1996, OBD2 became mandatory for all vehicles manufactured in the United States. In 2001, the European Union followed suit. OBD2 scanners should work on all cars manufactured those years or after.

As new vehicles are released, scanners are continuously updated with the ability to communicate with those models, but this process usually takes a few years.

Some vehicles manufactured in places like Canada and Japan have their own versions of OBD2. It’s best to double-check that your vehicle is compliant with any scanner before you purchase it.

Can you control your car through OBD2?

You cannot drive or steer your vehicle through an OBD2 port. However, you can control a range of automotive systems like the check engine lights, airbags, anti-lock brakes, and oil maintenance lights.

What problems can OBD2 scanners detect?

OBD2 scanners detect a standardized list of diagnostic trouble codes and check engine lights. Your vehicle will usually display a check engine light if any error codes are produced. The codes are five characters long and can be generic or specific about each problem. These computers can detect problems with the engine, transmission, emissions, electronics, airbags, and brakes.

What’s the difference between OBD1 and OBD2?

Before OBD2 was standardized, some automotive manufacturers used basic OBD1 ports to provide vehicle information, including 1984-1995 Ford and GM vehicles and 1989-1995 Chrysler and Toyota vehicles. OBD1 was generic regarding the information provided compared to OBD2.

OBD2 standardized error codes across manufacturers, whereas in OBD1 iterations, the same error code could signify different issues across various manufacturers.
