Decoding Diagnostic Trouble Codes (DTCs) in Mercedes-Benz vehicles can seem daunting, but with the right knowledge, it becomes a manageable task. The Panlong OBD2 scanner, when paired with a suitable Android app, can be your key to understanding these codes. This section provides a comprehensive guide to understanding Mercedes-Benz DTCs, including common codes, how to interpret them, and resources for further assistance.

3.1. Understanding the Structure of Mercedes-Benz DTCs

Mercedes-Benz DTCs follow a standardized format, making it easier to identify the system and component associated with the fault. The codes typically consist of five characters: one letter followed by four numbers. The letter indicates the system affected:

• P: Powertrain (engine, transmission)
• B: Body (airbags, central locking)
• C: Chassis (ABS, ESP)
• U: Network Communication (CAN bus)

The first number indicates whether the code is generic (0) or manufacturer-specific (1, 2, or 3). The remaining three numbers provide more specific information about the fault.

For example, a code like “P0300” indicates a generic powertrain code for random/multiple cylinder misfire detected. A code like “C1000” might indicate a manufacturer-specific chassis code for a fault in the ABS system.

3.2. Common Mercedes-Benz DTCs and Their Meanings

Here are some common Mercedes-Benz DTCs and their potential meanings:
