The Adapter Cable is designed to connect a Mercedes SD-Connect C4 multiplexer to individual pins of a control unit or vehicle wiring. The cable has the specific round connector for the SD-Connect interface on one end and multiple banana plugs on the other. This configuration enables direct access to specific electrical circuits for diagnosis and analysis.

This interface is intended for advanced diagnostic tasks where a standard OBD connection is insufficient. The color-coded banana plugs correspond to specific signals, such as CAN-bus High (CAN-H), CAN-bus Low (CAN-L), power and ground. This allows a technician to program control units on the bench (bench programming), locate communication faults on the CAN bus, or perform diagnostics on components not directly accessible via the OBD port.


Application and functionality:

The cable offers specialized functionalities for in-depth diagnostic procedures on Mercedes-Benz vehicles.

  • Direct pin-out connection: Enables a direct connection to the pins of a control unit (ECU) or other electronic modules.
  • CAN-bus diagnosis: Facilitates isolating and testing specific CAN networks (e.g., High-Speed and Low-Speed CAN) to detect communication errors.
  • Bench programming: Supports coding and programming of control units outside the vehicle, useful when replacing or repairing modules.
  • Flexible troubleshooting: Provides the ability to perform measurements on specific circuits not accessible via the standard diagnostic port.

Compatible vehicles and Application:

This Adapter Cable is not specific to a vehicle model but is designed for use with the Mercedes-Benz SD-Connect C4 and compatible C5 multiplexers. The cable can be applied to all Mercedes-Benz vehicles where direct access to the wiring of a control unit or CAN network is needed for diagnosis or programming.

Compatible diagnostic interface:

  • Mercedes-Benz SD-Connect C4
  • Mercedes-Benz SD-Connect C5

Important: Before purchasing the product, always check the connection of your vehicle. This may vary by model and year of manufacture.
