  Q: Is the Transmission Control Module an ESD sensitive electronic device that requires proper grounding and programming when replaced on Mercedes-Benz C320?

  A:

  One must also take care since the TCM is an Electro-Static Discharge (ESD) sensitive electronic component, i.e. any discharge of electric energy by your body may damage electrical parts. One must ensure that you ground yourself and the TCM correctly, and you do not touch the electrical bypass. Care should not be taken to confuse TCMs of different year vehicles. To reattach a scan tool to program the new unit when replacing the TCM a dealership service department or a qualified repair shop will be required and thus towing the vehicle to its facilities may be necessary. These models have the transmission control module built into the valve body of the transmission and with the sheer complexity and labor involved in servicing the transmission control module; it is advisable that this should be done in a dealership service department. In case of problems with the automatic transmission and the Diagnostic Trouble Codes confirms correct level of fluids, then it is possible to use Diagnostic Trouble Codes IVC with a scan tool in order to check the vehicle.
