OBD2 scanners have revolutionized car diagnostics, giving car owners and mechanics the power to understand and resolve car issues efficiently. But with so many OBD2, OBDII, BT Auto scanner, and code scanner options available, it can be overwhelming to know which one is right for you.

What is an OBD2 Scanner and How Does it Work?

An OBD2 scanner, also known as an OBDII scanner or car diagnostic scanner, is an electronic device that connects to your car’s onboard computer system through the OBD2 port. This port, typically located under the dashboard on the driver’s side, provides access to a wealth of data about your vehicle’s performance.

When you plug in an OBD2 scanner, it communicates with your car’s computer, retrieving diagnostic trouble codes (DTCs), also known as “check engine light codes.” These codes are like secret messages from your car, indicating potential problems with your engine, transmission, emissions system, and more.

Understanding OBD2 Scanner Codes

OBD2 scanner codes may seem cryptic at first, but they are standardized and relatively easy to decipher. Each code consists of five characters:

The first character: Indicates the system where the fault originated, such as “P” for powertrain (engine and transmission) or “B” for body.
The second character: Specifies whether the code is generic (0) or manufacturer-specific (1).
The third character: Pinpoints the specific system or component affected (e.g., fuel, ignition, emissions).
The last two characters: Identify the specific fault within that system.

For instance, the code “P0301” indicates a misfire in cylinder 1, while “P0420” suggests a problem with the catalytic converter system. You can easily find detailed information about specific autolink obd2 codes online or using a code lookup tool.
