• Second Character: Identifies whether the code is generic (0) or manufacturer-specific (1).
• Third Character: Specifies the subsystem (e.g., fuel system, ignition system).
• Fourth and Fifth Characters: Indicate the specific fault.

For example, a P0300 code indicates a random or multiple cylinder misfire in the powertrain system. A P0171 code indicates that the system is too lean (Bank 1).

MERCEDES-DIAGNOSTIC-TOOL.EDU.VN provides resources and guides to help you decipher DTCs and understand their implications for your Mercedes-Benz.
