OBD II Diagnostic Trouble Codes
(DTCs)
J2012 and ISO 15031-6 are standards for all DTCs, established by
the SAE, International Organization for Standardization (ISO) and
other governing bodies.
Codes and definitions assigned by these specifications are
known as Generic OBD II codes.
OBD II requires compliance to these standards for all cars, light
trucks, APVs, MPVs, and SUVs sold in the United States.
Codes not reserved by the SAE are reserved for the
manufacturer and referred to as Manufacturer Specific Codes.
DTCs are used to help determine the cause of a problem or
problems with a vehicle.
DTCs consist of a five-digit alphanumeric code.
The DTCs format and general code types are shown below.
Within each category (Powertrain, Chassis, Body and Network) of
