What is ODB2 Code Reader？

Reading code readers, commonly known as OBD2 scanners, are essential diagnostic tools for modern vehicles. They are designed to plug into the car's OBD2 port and read the fault codes stored in the vehicle's computer system. These codes can provide valuable information about the cause of a problem, which can then be used to guide repairs. Common fault codes include those related to the engine management system, emission controls, transmission, and other critical components. By using an OBD2 scanner, drivers and mechanics can quickly diagnose issues and get the vehicle back on the road with minimal downtime.

Common OBD2 Fault Codes and Their Meaning

OBD2 code readers can read a variety of trouble codes, which represent issues with different systems and components of a vehicle. Here are some common OBD2 trouble codes and their meanings:

These are just a few examples of the trouble codes in the OBD2 system, and the actual trouble codes can be more diverse, covering various aspects such as powertrain, chassis, body, and network. When an OBD2 code reader detects these trouble codes, they can help vehicle owners or technicians quickly identify the problem and take appropriate repair measures.
