This function is to read ECU version information and is the equivalent of "System Identification" or "System Information”
in some electronic control systems. These equivalent terms all refer to reading ECU-related software and hardware versions,
models and production date of diesel engines, part numbers, etc. This information is helpful when recording maintenance
records and ordering new parts
In the process of diagnosis, if the device shows “System is OK” or “No Trouble Code”, it means there is no related trouble
code stored in ECU or some troubles are not under the control of ECU. Most troubles are mechanical system troubles or
executive circuit troubles. It is also possible that the signal of a sensor may be inaccurate but within limits, which can be
examined using Live Data.
It allows for clearing current and historical trouble codes stored in the ECU memory, under the premise that all the troubles
have been resolved.
