BOSCH AUTO BOX GS8.87.0 - System Overview
Manufactured by Bosch, this ECU appears to compliment the Motronic M5.2.1 Engine management system. Not being Flash Programmable, there are two near identical systems sub numbered .0 and .1 with the main difference between the two being different shift points, different Gear lever switch inputs, and current gear indicator outputs. This version was fitted to all Automatic versions of the Discovery series II. It is an adaptive unit, which means that it learns and stores the driving habits of the owner and adapts to suit their driving style as well as overcome variations in engine power, etc which can be reset with this module. This ECU does support some OBDII compliant fault codes as well as a large number of codes outside of the standard which this module accesses.

SM030 - BOSCH AUTO BOX GS8.87.0 - Diagnostic Capabilities (Read Fault Codes)
Reads the fault code memory. The ECU can self detect up to 39 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.

SM030 - BOSCH AUTO BOX GS8.87.0 - Diagnostic Capabilities (Clear Fault Codes)
Clears the fault code memory.

SM030 - BOSCH AUTO BOX GS8.87.0 - 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.
