          AIR BAG - MERCEDES COMMANDER 

 Even when a small accident occurs, the Airbag control unit saves vehicle crash data (speed, brake pedal position, etc). This causes the Airbag lamp to stay ON all the time. If, after checking all parts of the Airbag system, everything is OK, the Airbag does not need to be exchanged with a new one. With this special function it is possible to read and write the EEPROM as well as clear the crash data of the following Airbag control units by OBDII:

 -Bosch Up to 1997
- Bosch 1997-1998
- Bosch 1998-2003
- Bosch 2004-2009
- Temic Up to 1994
- Temic 1995-1997
- Temic 1997-1999
- Temic 1999-2002
- Temic 2003-2009

Additionally, owners of this special function can clear crash data of vehicles produced after year 2005 by OBD connection. You just have to connect to the Airbag by standard diagnostics and press the button "Clear Crash Data".
It is also possible to unlock and lock to a vehicle, as well as erase operating hours in Airbag control units, which store this information.
The Dump Tool special function contains a database of Airbag control units with their part numbers and it is possible to reset many control units by EEPROM Dump.

                DUMP TOOL - MB 

This application needs the EEPROM dump, which has been saved as a file, from the corresponding unit. After the dump file is loaded, some modifications will be made and you need to store the dump as a new file, which you can program with a special programmer into the device that the dump is from.
The dump tool receives as input a dump file from the corresponding unit (input dump is loaded with the "Load dump" button). The dump file can be read either via OBDII but also with a programmer (especially for units where reading via OBDII is not possible). As output the dump tool displays some data extracted from the input file and/or makes some modifications to the input data. If modification were made (for some sub-functions there are no modifications made, only data are visualized) the user has to write the modified dump to desired file (with the "Save dump" button), and then this modified dump should be saved back to the device via OBDII or with a programmer.
If data are read/written with a programmer the user must make sure that the proper byte order is used. Because most of the programmers are reading the data on 16bit words, the byte order in the dump depends on the used programmer - some programmers produce dumps starting with the least significant byte, and some produce dumps starting with the most significant byte. This means that for the same unit two different programmers can produce different dumps. For that purpose a button "Swap bytes" is provided. This buttons changes alternatively the byte order into the dump. So, if after loading the dump file into the dump tool data cannot be extracted or modified, please try to swap the bytes to get a correct result.

Repair ALL Sensotronic Brake Control fault by OBD

With the help of the special function "EEPROM Read/Write" it is possible to read/write completely the EEPROM of the Sensotronic Brake Control (SBC) control unit.
You do not need an additional programmer to read the MCU from the SBC. After reading the EEPROM it is very easy to repair the dump with the help of the special function "Dump Tool". These functions require special license MN005.

Works for the following vehicles : W211, W219, R230.

 The Sensotronic Brake Control unit is a unique unit. Mercedes-Benz were one of the first vehicle manufacturers to employ a brake-by-wire system on a car (W211, R230). Called sensotronic (SBC), the system no longer relies on the driver to produce hydraulic pressure. The brake pedal is connected to the computer (ECU) by wire (brake-by-wire). The sensors on the brake pedal will inform the computer how the pedal is pressed, for example how far, how fast etc. The computer will then dissipate the required force to each wheel via modulators.
The SBC module counts breaking cycles, after exceeding the value of 300000, an error message occurs. It is a kind of protection for the mechanical parts like the motor, inside the traction system hydraulic unit (A7/3). The contents of the message and the value of cycle limiter differs depending on the software version. It can be for example: "Brake defective stop vehicle" or "SBC defekt, sofort Händler aufsuchen".
The Fault Code (DTC) that is stored is:
C249F OPERATING TIME OF COMPONENT A7/3 IS EXCEEDED (SBC HYDRAULIC UNIT)

The procedure to repair the SBC control unit completely by OBD is the following:

1. Open special function "EEPROM Read/Write" and select "Sensotronic Brake Control".
2. Press the button "Read EEPROM" and save the EEPROM dump to a file on your laptop or PC.
3. Open the special function "Dump Tool" and load the saved EEPROM dump from the SBC.
4. Press the button "Paramaters" and select the option tp repair the dump.
5. Save the modified EEPROM dump to a new file.
6. Open special function "EEPROM Read/Write" and select "Sensotronic Brake Control".
7. Load the already repaired EEPROM dump from the SBC and press the button "Write EEPROM".
