Within each general category, the DTCs are assigned to specific ranges that
cover certain vehicle systems.

J2012 and ISO 15031-6 are standards for all DTCs, established by the SAE,
International Organization for Standardization (ISO) and other governing bod-
ies. Codes and the definitions assigned by this specification are known as
Generic OBD II codes. OBD II requires compliance of this standard, and has
made it a standard for all cars, light trucks, APVs, MPVs, and SUVs sold in the
U.S. Codes not reserved by the SAE are reserved for the manufacturer and
referred to as Manufacturer Specific.
