4. Frequently Asked Questions About OBD2 Scanners

Still have questions about OBD2 scanners? We’ve compiled a list of frequently asked questions to help you better understand these powerful diagnostic tools.

4.1. What is an OBD-II Scanner?

An OBD-II scanner is a device used to access information from a vehicle’s onboard computer. It connects to the OBD-II port, which is a standard port found in most modern vehicles. The scanner reads and interprets error codes, monitors real-time data, and performs diagnostic tests. According to the Environmental Protection Agency (EPA), OBD-II systems are designed to monitor the performance of a vehicle’s engine and emissions control systems, ensuring compliance with environmental regulations.

4.2. What is the OBD-II Port?

The On-Board Diagnostics Version Two (OBD-II) port is the standard port found on almost all passenger vehicles sold in the United States since 1996, in Canada since 1998, in the European Union since 2004, and in Australia, Mexico and New Zealand since 2006. This port is where you plug into the car and interface with the onboard computer. A variety of devices can be plugged into the OBD-II port including OBD-II scanners, insurance black boxes, and more recently dash cams. If you’re unsure where an OBD-II scanner plugs in, here’s how to find your car’s OBD-II port on North American cars. If you’re living elsewhere, here’s how to find your OBD-II/EOBD port worldwide.

4.3. What is a DTC?

DTC is short for Diagnostic Trouble Code, which is the error code a car’s OBD system generates when it spots an issue. These are the codes read by OBD-II scanners that allow the user to figure out what’s going on under the hood. There are a lot of standardized DTC codes that are the same across different makes and models of vehicle, though some manufacturers employ their own DTCs that are unique to one or more of their vehicles

4.4. What do DTCs actually mean?

If you’re unfamiliar with how DTCs are written, then they probably look like complete gibberish – a random selection numbers and letters that mean very little to you. Fortunately there is some logic, which will give you an idea of what errors the car has detected.

The first letter confirms which of the car’s main systems is experiencing the issue. Those are the Powertrain (P), Body (B), Chassis (C) and Network (N). The second is a number designating whether this is a generic code (0) or a manufacturer specific code (1).

The third character then identifies exactly which system is experiencing the issue.

• 1 is fuel and air metering
• 2 is an injector circuit specific fuel and air metering code
• 3 is the ignition system or a misfire
• 4 is an auxiliary emissions code
• 5 concerns vehicle speed controls and idle control systems
• 6 is for computer auxiliary outputs
• 7, 8 and 9 are for transmission and gearbox faults
• A, B and C are for hybrid-specific propulsion faults

The fourth and fifth character then confirms the exact fault, and can be any number between 0 and 99.

OBD-II scanners are able to describe what these error codes mean, though more advanced models will be able to give you more information. It may require some time on Google, and as you can imagine there are a lot of possible DTC errors you may encounter. Over 5,000, in fact.

Not all DTCs are critical issues, though. While they will detail major problems experienced by your problem, the error code may just be warning you that the engine temperature is a little too high.
