Diagnosis

4.1. Menu Options

4.1.1. After the scanner is connected to the vehicle and paired with EZ500 mainframe via wired or wireless connection, diagnosis can be performed. The diagnostic interface is as shown below:

4.1.2. Users can choose the relevant menu for the vehicle being tested: selection for Europe will enter the European cars menu, selection for Asia will enter the Asian cars menu, selection for America will enter the American cars menu. Users also can input the vehicle model to search.

4.1.3. Besides the usual system diagnostic functions, XTOOL have also developed a series of special diagnostic functions for certain vehicles as follows:

4.2. Test Functions

4.2.1. Using VW as an example, select Diagnosis, then select EUROPE. Choose the VW logo. If the logo is not showing on the screen, please swipe up or down to display it.

PLEASE NOTE: Different vehicles have different menus and systems.

Common main function menu includes the following options:

Read ECU: This function is to read the ECU version information, which is the equivalent of “System Identification” or “System Information” in some electronic control systems.

This will allow you to read ECU related software and hardware versions, models and production date of diesel engine, part number, etc.

Read DTCs: read the trouble codes that are stored in the ECU.

Clear DTCs: clear current and historical trouble codes memory in ECU. The trouble codes can not be erased without eliminating the fault that the code relates to. TIP: Save or print the currently stored fault codes before clearing them to provide help in the case of an intermittent fault.

Read Live Data: This will allow you to read the parameters of the system being interrogated, such as oil pressure, temperature, engine speed, fuel oil temperature, coolant temperature, intake air temperature, etc.

Special Functions: Typically these will include Injector programming, DPF Regeneration/reset, component learning etc.

Actuation/Activate Components Test: Activations allow you to operate supported components for troubleshooting purposes. Components range from instrument cluster indicators, to the engine injection valves, to the boot lid latch.

Activations are also used to test components for function and to check systems for correct operating ranges.

4.2.2. Toolbar function buttons descriptions

Function Buttons	Descriptions
	Returns to previous interface
	Print test data
	Click to record the data, click again to send your feedback to XTOOL service center

After clicking the data record button the second time the data feedback page will appear as shown below, showing diagnostic software version, vehicle being tested, and the steps performed in the diagnostic process. Users can then enter the nature of the problem and any other relevant information and send the form to the Xtool engineering department.

4.3. Read ECU

This function is used to read ECU version information, which is the equivalent of “System Identification” or “System Information” in some electronic control systems.

This will allow you to read ECU related software and hardware versions, models and production date of diesel engine, part number, etc. shown below:

4.4. Read DTCs

Select Read Fault Codes to read the trouble codes stored in the ECU. The screen will show the trouble codes and their definition, shown below:

Tip: In the process of diagnosis, if the device shows “System is OK” or “No Trouble Code”, it indicates that the ECU has not detected a fault in any of the circuits that it monitors. If there is a fault which is not being recorded it may be that the fault is with a part of the system not under the control of ECU, such as a mechanical system fault. It is also possible that the signal of a system sensor may be incorrect but still within the ECUs stored limits, this can be verified in Live Data.

4.5. Clear DTCs

4.5.1. Return to the previous step, select Clear Fault Codes to clear the current and historical trouble codes memory in ECU. Performing this function will clear all the current and historical trouble codes. Please ensure that the trouble codes have been recorded before clearing, shown below:

4.5.2. Click YES to confirm the operation, if the communication is normal, it will show “Trouble Codes Successfully Cleared” or “Trouble Codes Cleared”. Generally, users will need to re-read trouble codes after clearing them to confirm that the trouble codes have been cleared.

4.6. Read Live Data

System control units or ECUs send out operating parameters and working status of various components in the form of an 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.

Tip: Live Data is important function that can be used to help technicians further diagnose a problem. This function requires technicians to be familiar with sensor data of each system, control signals and control modes. Tip: Save known good live data readings for comparison.

(The following are some test conditions and typical values of common live data)

Test Items	Unit	Normal Data	Test Conditions & Typical Values
1.Engine Speed	rpm	0-6000	Engine warmed-up: 750-850rpm
2.Engine Coolant Temperature	℃	-40-150	Engine warmed-up: 85-95℃
