1. Decoding Mercedes Sprinter Fault Codes

Understanding Mercedes Sprinter fault codes is crucial for diagnosing and resolving issues efficiently. These codes, also known as Diagnostic Trouble Codes (DTCs), are generated by your vehicle’s onboard computer system when it detects a problem. Each code corresponds to a specific fault, providing technicians with a starting point for troubleshooting. Think of them as a coded language your Sprinter uses to communicate its needs. Recognizing the anatomy of these codes can help you effectively address those needs.

1.1. Understanding the DTC Structure

DTCs typically consist of a five-character alphanumeric code. Each character provides essential information about the fault. Here’s a breakdown:

• First Character: Indicates the general system where the fault occurred.

  • B (Body): Relates to components like lights, windows, and locks.
  • C (Chassis): Concerns systems such as ABS, traction control, and suspension.
  • P (Powertrain): Covers engine, transmission, and fuel system issues.
  • U (Network & Vehicle Integration): Relates to communication between different control modules.

• Second Character: Specifies whether the code is generic or manufacturer-specific.

  • 0: Generic (SAE) code, applicable to all vehicles.
  • 1, 2, or 3: Manufacturer-specific code, unique to Mercedes-Benz.

• Third Character: Identifies the specific subsystem.

  • 0: Fuel and air metering and auxiliary emission controls
  • 1: Fuel and air metering
  • 2: Fuel injector circuit
  • 3: Ignition system or misfire
  • 4: Auxiliary emission controls
  • 5: Vehicle speed controls and idle control system
  • 6: Computer output circuit

• Fourth and Fifth Characters: These provide further detail about the specific fault within the identified system and subsystem. They help to pinpoint the exact component or circuit that is malfunctioning.

1.2. Interpreting Mercedes-Benz Specific Codes

Mercedes-Benz, like many manufacturers, uses its own set of specific codes to provide more detailed information about vehicle issues. These codes, often starting with “1,” “2,” or “3” in the second character, can help you diagnose problems more accurately than generic OBD-II codes alone. For example, a manufacturer-specific code might indicate a specific sensor failure or a particular wiring issue that a generic code would not reveal.

2. Comprehensive Mercedes Sprinter Fault Codes List

Here is an extensive list of Mercedes-Benz DTC codes as of 2018, covering all Sprinter Van models. This list is organized by system (Body, Chassis, Powertrain, and New Systems) for easy navigation.

2.1. Body (B) Codes

Body codes relate to various comfort, convenience, and safety systems within the vehicle.

2.2. Chassis (C) Codes

Chassis codes relate to the vehicle’s handling, stability, and braking systems.

2.3. Powertrain (P) Codes

Powertrain codes pertain to issues within the engine, transmission, and related systems. This is often the most critical category, as these faults can significantly affect vehicle performance.
