SM050 - SIEMENS TRANSFER BOX (NGRR) - Diagnostic Capabilities (Read Fault Codes)
Reads the fault code memory. The ECU can self detect up to 31 different problems with itself, its wiring and its associated sensors, storing the respective code if it detects any malfunction or reading outside of pre defined acceptable limits. Not all stored faults may cause the fault warning lamp to illuminate.

SM050 - SIEMENS TRANSFER BOX (NGRR) - Diagnostic Capabilities (Clear Fault Codes)
Clears the fault code memory.

SM050 - SIEMENS TRANSFER BOX (NGRR) - Diagnostic Capabilities (Settings)
Values, configuration settings, and other stored information which can be read from the ECU, edited and then rewritten back. Read settings can also be stored as a standard HTML page for reference. These pages can then later be re loaded and re written back to the ECU. Please note that some values may be read only due to the fact that they are supplied from the ECU’s ROM or are internally calculated.

  • Part Number: This is the manufacturer's part number for the ECU.
  • Hardware number: This is the hardware version which denotes the processor and circuit board type.
  • Software number: This denotes the coding inside the processor for the hardware.
  • Supplier number: This is a number which defines the supplier using a standard look up list of supplier ECU manufacturer numbers.
  • Coding index: This is the coding identification for the programming maps.
  • Diagnostic index: This is a number that indicates the diagnostic capabilities support level.
  • Bus index: This is a number that indicates the bus communication support level, the vehicle communication buses.
  • Day of Build: This is the day in which the unit was built.
  • Month of Build: This is the month in which the unit was built.
  • Year of Build: This is the year in which the unit was built.

SM050 - SIEMENS TRANSFER BOX (NGRR) - Diagnostic Capabilities (Inputs)
Realtime live display of the information the electronic control unit of the selected vehicle system is currently deriving from its input sensors.

  • Sensor Voltage: This is the voltage for the sensors of the transfer box ECU.
  • Battery Voltage: This is the battery voltage as measured by the transfer box ECU.
  • Range Change Request: This denotes if the range change has been requested or not.
  • Neutral Request: This denotes if a neutral request has been detected by the transfer box ECU. A neutral request is activated by putting a fuse into position number 37 on the passenger fuse box on the Range Rover. This is typically required for towing purposes.
  • RAW Potentiometer Reading: This is the current voltage from the potentiometer.
  • Potentiometer Reading: This is the calculated reading for the potentiometer in degrees.
  • Current Reading: This displays the current reading of the ECU in amps.
  • Torque Limit: This is the torque limit of the transfer box as a percentage.
  • Motor State: This denotes if the motor is moving clockwise or moving anti clockwise or stalled.
  • Shaft Speed: This denotes the output shaft speed as measured by the ECU in kilometres per hour.
  • Range Status: This shows the current range status.
  • Target Range: This is the user selected range.
  • Front Left/Front Right/Rear Left/Rear Right Wheel Speed: This is the wheel speed of the specific wheel in both kilometres per hour and miles per hour.
  • Vehicle Speed: This is the current vehicle speed in both kilometres per hour and miles per hour.
  • Engine Speed: This is the current engine speed in RPM.
  • Gear Position: This denotes if the gear selected is Park, Neutral or Drive.
  • Gear: The current gear of the gearbox.
