Users can choose menu based on their actual needs from EZ400 PRO Diagnostic Tool:
selection for Europe means entering European cars menu, selection for Asia means entering Asian cars menu, selection for America
means entering American cars menu, selection for China means entering Chinese cars menu. Users also can input vehicle model to search.
Take Volkswagen car for example, select Diagnosis, then select Europe Car, users can see Volkswagen’s logo. If the logo has not been seen,
please swipe up and down or enter the car model to research.
Different vehicles have slight different menus.
Common main function menu includes the following options:
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, shown as below.
Select Read Trouble Codes to read trouble codes stored in ECU. Screen will show the trouble code and its definition when read the trouble
codes, shown as below.
Tip: 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 of these troubles are mechanical system troubles
or executive circuit troubles, it is also possible that signal of the sensor may bias within limits, which can be judged in Live Data.
Return to the previous step, select Clear DTCs to clear current and historical trouble codes memory in ECU. Performing this function
will clear all the current and historical trouble codes. Make sure whether the trouble codes have been recorded before clearing, shown as below.
Click YES to make clear confirmation, if the communication is normal, it will show “Trouble Codes Successfully Cleared” or
“Trouble Codes Cleared”. Generally, users need re-read trouble codes after cleaning them to confirm whether the trouble codes
have been cleared.
Read Live Data
Auto ECUs send out operating parameters and working status of various components in the form of Electronic Signal, here Electronic Signal
refers to Live Data. Common Engine Live Data includes Engine Speed, Throttle Position Sensor Voltage, Oxygen Sensor Voltage, Coolant
Temperature, Spark Advance Angle, Idle Speed Switch State, Intake Air Temperature, Intake Pressure, etc.
Tips: Live Data is the important function for maintenance technicians to further diagnose the troubles. This function needs maintenance
technicians very familiar with sensor data of each system, control signals and control modes, all which are the indispensable basis of using
Live Data function for maintenance technicians.
There are two modes to view Live Data, users can choose optimum mode according their own needs and different parameter types.
Dashboard Mode: Display parameters in the form of simulating instrument graphics.
Graph Mode: Display parameters in the form of graph.
More special function will be found in different vehicle models.
Test Conditions: Ignition on engine off
If engine started or rotation speed signal recognized, actuating component diagnosing will be interrupted.
In the process of actuating components diagnosis, single component will always be in the trigger status until the next component being activated.
Before repeating actuating components diagnosis, users should start engine in short-time, or turn ignition off for 2 seconds.
Actuating components can be checked by hearing or touching.
In the process of all actuating components diagnosis, electric fuel pump is always working.
10 minutes later, actuating components diagnosing is terminated.
Actuating Component: it is responsible for executing various instructions issued by ECU, which is the instruction completer.
Return to Dynamic Diagnostic Data, enter Actuating Components Test and it will show the menu of the actuating components
that carry out action test, shown as below.
EZ400 PRO Diagnostic Tool use Tip: Actuating Components Test performs function tests for parts of system actuating components. When performing this function,
the diagnostic tool will take action test by simulating ECU signal to judge whether the actuating components or circuits are good.
Return to Dynamic Diagnostic Data, enter Actuating Components Test and it will show the menu of the actuating components that carry out action test.
