Understanding OBD2 Codes

OBD2 codes are standardized and consist of a five-character alphanumeric code. The first character indicates the system affected (e.g., P for powertrain, B for body, C for chassis, U for network). The second character specifies whether the code is generic or manufacturer-specific. The remaining three characters pinpoint the specific problem area.

Interpreting these codes accurately requires a reliable database or guide. Many OBD2 scanners and reset tools come with built-in code libraries, while others provide access to online databases. Understanding these codes is the key to diagnosing and fixing car problems effectively.
