At Qmotors we use genuine Mercedes-Benz diagnostics software allows you to perform complete diagnostics of all 1995-present Mercedes-Benz models. Diagnostics is performed via OBD-II connector (which is located near steering wheel) or via Mercedes-Benz proprietary 38pin connector (only older cars, pre-2001). Our PC USB diagnostics interface supports over 26 multiplexed K-Lines and Mercedes-Benz diagnostics CAN-BUS interface (also known as CAN-D).
Unlike other universal Mercedes-Benz car scanner tools which only read fault codes, this software performs nearly ALL the functions like the original dealer diagnostic tool. Our Mercedes-Benz diagnostic interface contains K-Line multiplexor, CAN-BUS interfaces and SAE J1850 bus (both PWM and VPW).
The following diagnostic functions are supported:
Displays complete identification of control unit, e.g. part number, software/hardware version, manufacturer, etc…
Read fault codes
Displays all stored and pending fault codes with complete description (e.g. “Rail pressure – too low pressure”).
Program supports report printing or copy to clipboard.
Clear fault codes
This function clears all stored fault codes and other diagnostic information.
Auto-scan (complete car scan/test)
Detects all Mercedes-Benz ECUs (electronic control units) installed in car and reads all diagnostic fault codes.
Program displays live Data like Engine Speed, Battery voltage, Oxygen Sensor, Coolant Temperature, etc. Values can be displayed in graph, 9 values at once, or full listing (all measured values). Logging to file is also supported, which allows offline analysis.
Actuator test activates particular actuator (e.g. turn on fuel pump, lock/unlock wheel, lock/unlock doors, cut off fuel, etc..)
This feature is of great importance in all vehicles because systems like Engine control units, Immobilizers, Airbags, Alarms, Body Control Units, and some others, require you to perform reset or programming procedures after car repair is done, or even configuration after replacing broken Control Unit.
