Xtool EZ300 Pro Function:
Different vehicles have slight different menus.
Common main function menu includes the following options:
Read ECU: this function is to read ECU version information, which is the equivalent of “System Identification” or “System Information” in some electronic control systems, all mean to read ECU related software and hardware versions, models and production date of diesel engine, part number, etc. It is convenient for us to make record in the maintenance process, and it also makes later date feedback and management easier.
Read DTCs: read trouble codes stored in ECU.
Clear DTCs: clear current and historical trouble codes memory in ECU, under the premise that all the troubles are eliminated. The trouble codes can not be erased without eliminating all the troubles, which will cause the diagnostic tool always reading the trouble code because the code will always be saved in ECU.
Suggestion: users should better not to clear trouble codes, we need record the trouble details after reading code, which is provided as reference for maintenance. After dealing with troubles, there will be no trouble code when we re-read.
Read Live Data: that is to read the parameters of running engine, such as oil pressure, temperature, engine speed, fuel oil temperature, coolant temperature, intake air temperature, etc. Based on these parameters, we can judge directly where the problem lies, which helps to narrow the scope in maintenance. For some vehicles, during their actual operation, the problems such as performance characteristics offset, sensitivity reduction, can be judged in live data. This function needs us very familiar with engine parameters, for instance, when idle speed is 800RPM or 750RPM, coolant operating temperature is between 80～105℃, what are the operating voltage and time of each sensor and actuator
Special Functions: depends on vehicle models.
