Explanation of OBD Codes

The Engine OBD Codes are categorised into four different systems.

Body (B-codes) category covers functions that are, generally, inside of the passenger compartment. These functions provide the driver with assistance, comfort, convenience, and safety.

Chassis (C-codes) category covers functions that are, generally, outside of the passenger compartment. These functions typically include mechanical systems such as brakes, steering and suspension.

Powertrain (P-codes) category covers functions that include engine, transmission and associated drivetrain accessories.

Network & Vehicle Integration (U-codes) category covers functions that are shared among computers and systems on the vehicle.
