OBD-Codes.com provides a list of most automotive error codes. However, some error codes that are manufacturer-specific might not be available. Automotive error codes are comprised of a letter and a series of digits. The first letter indicates the system from which the error originated: P for powertrain, B for body, C for chassis and U for undefined. The second digit shows whether the code is generic or manufacturer-specific: 0 is generic and 1 is specific. The third digit shows the code's subtype, while the fourth and fifth digits are problem-specific. Once the error code is discovered, a person can search Actron.com using a code lookup that is specific to the vehicle's year, make, model and engine.
