TCM-013 VGS3-FDCT 5-Pin TCU Cable for Mercedes-Benz

The TCM-013 is a dedicated Telematics Control Unit (TCU) interface cable for Mercedes-Benz vehicles. It features a specific 5-pin connector (commonly known as the VGS3-FDCT connector) on one end for direct connection to the vehicle's communication module or antenna amplifier, and a standard OBD2 connector on the other end. This cable is engineered to provide a direct diagnostic and programming link to Mercedes-Benz telematics hardware.

Function

This cable is used for advanced diagnostics, coding, and programming of Mercedes-Benz telematics and communication systems. Its primary functions include accessing the TCU for reading/clearing fault codes, performing software updates (SVM/flashing), coding new TCU modules during replacement, and configuring features related to the HERMES or NTG communication platforms, such as emergency call (eCall), telematics services, and antenna system diagnostics.

Support Car Models

This cable is compatible with select Mercedes-Benz models from approximately 2013 onwards that utilize the specific 5-pin VGS3-FDCT connector for their Telematics Communication Unit or antenna module. This includes many models equipped with NTG 4.5, NTG 5, NTG 5.5, and NTG 6 (MBUX) infotainment systems, such as the C-Class (W205), E-Class (W213), S-Class (W222), GLC (X253), GLE (W166), and related variants.
