BOSCH AUTO BOX GS8.60.1 - Physical Details

SM051 - BOSCH AUTO BOX GS8.60.1 - Diagnostic Capabilities (Read Fault Codes)
Reads the fault code memory. The ECU can self detect up to 45 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.

SM051 - BOSCH AUTO BOX GS8.60.1 - Diagnostic Capabilities (Clear Fault Codes)
Clears the fault code memory.

SM051 - BOSCH AUTO BOX GS8.60.1 - 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.
  • Week of Build: This is the week in which the unit was built.
  • Year of Build: This is the year in which the unit was built.

SM051 - BOSCH AUTO BOX GS8.60.1 - 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.
