What type of code reader do I need for my car?
If your car is experiencing issues, you may need to use a code reader to diagnose the problem. A code reader, also known as an OBD2 scanner, is a device that plugs into your vehicle's onboard diagnostics (OBD) port and reads the diagnostic trouble codes (DTCs) stored in the car's computer system. These codes can provide valuable information about what's causing the problem, allowing you to address it more effectively.
Understanding OBD2 Scanners
OBD2 scanners come in a variety of types, from basic code readers to more advanced diagnostic tools. The type of code reader you need will depend on the specific issues you're experiencing with your car and the level of information you require. Basic code readers can read and clear diagnostic trouble codes, while advanced scanners can provide more detailed information, such as live data from the vehicle's sensors and the ability to perform specific tests.
- Basic code readers: These are the most affordable and accessible type of code reader. They can read and clear diagnostic trouble codes, but may not provide much additional information.
- Advanced scanners: These more sophisticated tools can provide a wealth of information, including live data from the vehicle's sensors, the ability to perform specific tests, and the option to update the scanner's software as new features become available.
When choosing a code reader, consider the specific needs of your vehicle and the level of information you require to diagnose and address any issues.
Connecting the Code Reader
To use a code reader, you'll need to locate the OBD2 port in your vehicle. This port is typically located under the dashboard, near the steering column, or in another easily accessible area. Once you've found the port, simply plug in the code reader and follow the on-screen instructions to read the diagnostic trouble codes.
With the right code reader, you can quickly and easily diagnose issues with your car, saving time and money on costly repairs. By understanding the different types of code readers available and how to use them, you can take a more active role in maintaining the health of your vehicle.
What is the difference between a car code reader and scanner?
Scan tools provide you with live data and are significantly more in-depth with their diagnoses than code readers. Code readers are used to retrieve and clear DTCs, displaying generic codes to let you know if there's anything wrong with your vehicle.
Do all code readers work on all cars?
In theory, yes, since all vehicles manufactured after 1996 in the U.S. must support OBD2 standards. But there's a catch. While OBD2 scanners should work on most cars, several factors can affect compatibility. These include the vehicle's make, model, and year, as well as the specific protocols it uses.
What code readers do mechanics use?
Whenever you take your car to a mechanic, 99% of the time the first thing the tech will do is plug in an OBD-II scanner to learn what's wrong with the car. But you can skip that potentially costly process and figure out the issue yourself—if you have an OBD-II scanner.
What vehicles use OBD1?
OBD stands for On-board diagnostics. The two main types of diagnostic systems in vehicles is OBD1 and OBD2. OBD1 was used in vehicles up to as late as 2006 and anything newer will be OBD2. Some vehicles manufactured earlier than 2006 are still OBD2 For example: You own a 2003 Toyota Corolla, this is OBD1.
What are the disadvantages of OBD2?
Inaccurate Readings: Poorly made scanners may deliver incorrect or incomplete readings, leading to misdiagnoses that could prompt unnecessary repairs or cause you to miss real issues. Compatibility Issues: Some low-end scanners may not be fully compatible with newer or less common vehicle models.

Do I need OBD1 or OBD2?
There are two main types of OBD systems: OBD1 and OBD2. OBD1 was the original system, and it was used on vehicles from the early 1990s to mid-1990s. OBD2 is the newer system, and it is used on all vehicles manufactured since 1996.
Is there a difference between OBD and OBD2?
It offers better signaling protocols and messaging formats, yielding more accurate results in emission tests and standardizing trouble codes for engine issues. While OBD1 is directly connected to the vehicle's console for diagnostics, OBD2 operates remotely, often using Bluetooth for data reading.
How do I choose a car code reader?
One of the keys to getting the best general-purpose scan tool is to make a priority list of the vehicles you work on, then find the tools that offer the best coverage for those makes. The best way to learn about the tool is to use it.
