3.6 OBDII 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 specifica-
tions are known as Generic OBDII codes.
• OBDII 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 Spe-
cific 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 DTC format and general code types are shown below.
1. Bx = Body
Cx = Chassis
Px = Powertrain
Ux = Network communication
x - 0, 1, 2, or 3
2. Vehicle specific system
3. Specific fault designation
