Each code corresponds to a specific problem, ranging from minor issues like a loose gas cap to more serious problems like engine misfires or transmission malfunctions.

The first character represents the system where the fault occurred (e.g., “P” for Powertrain, “B” for Body, “C” for Chassis, and “U” for Network). The second character indicates whether the code is generic (“0”) or manufacturer-specific (“1”). The remaining three characters specify the specific fault within the system.
