Mercedes Star Diagnosis SDConnect C4 in C5 housing is identical to the classic multiplexer circuit design and equipment of five cables. It functionally completely repeats the classic version. Just like the classic SDConnect, it has a full disable feature, white serial number, firmware updated to the latest version.
After connecting the network cable, toolkit is connected, but DAS doesn’t work. If I disconnect the OBD cable, C4 will turn off. If I connect the OBD cable, C4 will turn on and the screen displays shown as below, but the network fails to connect.
