Understanding OBD2 Codes

Once you’ve chosen your OBD2 scanner, it’s time to understand how to interpret the codes it retrieves.

Types of Codes: OBD2 codes generally fall into four categories:
- P Codes: Powertrain codes, related to the engine, transmission, and emissions systems.
- B Codes: Body codes, related to components like airbags, power windows, and central locking.
- C Codes: Chassis codes, related to the ABS, traction control, and other chassis systems.
- U Codes: Network codes, related to communication issues between the vehicle’s various control modules.
Code Structure: OBD2 codes consist of a letter and four digits:
- First Character: Indicates the system (P, B, C, U).
- Second Character: Indicates whether the code is generic (0) or manufacturer-specific (1).
- Third Character: Identifies the specific system or sub-system.
- Fourth and Fifth Characters: Pinpoint the specific fault or issue.

Example:

A code “P0301” would indicate a powertrain (P) code, generic (0), related to the ignition system or misfires (3), and specifically a misfire detected in cylinder number 1 (01).
