10. Frequently Asked Questions (FAQs) About Good Car Scanners

What is a Good Car Scanner?

A good car scanner is a device used to diagnose issues with a vehicle by reading data from its onboard computer. It helps identify problems, monitor performance, and make informed decisions about maintenance and repairs.

What is the OBD-II Port?

The On-board Diagnostics Version Two (OBD-II) port is the standard port 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.

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

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.
