STEERING ANGLE (L322) - System Overview
This ECU is fitted as standard to all L322 range Rovers and is located on the lower portion of the steering column. Its main function is to interact via the CAN bus with the DSC 5.7 ECU to give it instant information regarding driver input and current wheel angle for it to make stability safety calculations.

STEERING ANGLE (L322) - Physical Details

SM052 - STEERING ANGLE (L322) - Diagnostic Capabilities (Read Fault Codes)
Reads the fault code memory. The ECU can self detect up to 16 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.

SM052 - STEERING ANGLE (L322) - Diagnostic Capabilities (Clear Fault Codes)
Clears the fault code memory.

SM052 - STEERING ANGLE (L322) - 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 ECUís ROM or are internally calculated.
