OBD-II compliant:. J compliant:. Most diesel engine manufactured vehicles or equipment are J compliant. If you are unsure whether your vehicle is OBD-II or J compliant, check your vehicle manual, research online, or consult with your dealership to confirm compatibility. DTC codes are five characters long. The first character is always a letter. It indicates which control system has an issue, and has the following possible values and meanings:.
P powertrain refers to the engine, transmission, fuel system, and associated accessories. C chassis refers to mechanical systems generally outside the passenger compartment such as steering, suspension, and braking. B body refers to parts mainly found in the passenger compartment area. The second character is a digit, typically 0 or 1, and shows whether or not the code is standardized. These codes are unique to a specific car make or model and are typically less common.
Most of the time, 2 or 3 indicates that a code is manufacturer-specific, with only a few exceptions. The third character is also a digit, ranging from 1 to 8.
