Starting the Mercedes FBS4 Manager and overview of the modules and buttons (AVDI)

The Mercedes FBS4 Manager is the Abrites online server-based software for working on the DAS modules of Mercedes vehicles built on the FBS4 platform. This guide covers how to open it, which modules you can select and what each button does, before you start any control unit replacement.

Procedure

1. Connect the AVDI to the PC and to the vehicle with the CB106 OBDII cable; check the unique ID number of your interface in the "license viewer" installed on the PC.
2. Start the Abrites Quick Start application and select the Mercedes icon first.
3. When the main "Abrites Diagnostics for Mercedes" screen opens, select "Mercedes FBS4 Manager".
4. On the FBS4 Manager main screen pick the unit you want to work on: Electronic Ignition Switch (EZS/EIS), Engine Control Unit (ECU), Transmission Control Unit (TCU), Electronic Steering Lock (ESL), Direct Select Module (DSM/DSM222), Car Key, 48V starter-alternators of the INV20EM01 family (hybrid vehicles), Electric motor 1 & 2.
5. Use "Info" to establish the connection and read the unit type and its status (virgin, personalized, activated).
6. Use "Save" to read the FBS data and save it to a file on the PC: this is the backup you will need to personalize the donor module.
7. Use "Personalize" to write the previously saved FBS data to the unit, "Virgin" to return the unit to virgin state (ready for personalization), "VIN" to write the VIN into the module and "Repair" to start the electronic steering lock (ESL) repair procedure.
