3.2. Precautions before Use
3.2.1. The vehicle power supply has to meet the normal voltage limits DC 9-15V
3.2.2. Users should check the position of the DLC port and ensure the OBDII 16pin connector and the
DLC port are correctly aligned before attempting to connect.
3.2.3. When taking some special functions tests, users are required to operate the device according to
operating instructions. For vehicle, it has to strictly meet the requirements, for example, the
conditions that some vehicle models need to be reached are as follows: engine temperature
80℃/105℃, turn off the loads (such as headlights, air-conditioner, etc.), put accelerator pedal in
released position, etc.
3.2.4. If users can not find the tested vehicle model or electronic control system in the X100 PAD2 test
menu, they may need to update the software or consult Xtool technical service department.
3.2.5. Please ensure that only official XTOOL cables and connectors are used to prevent damage to the
unit.
3.2.6. Before powering off the unit, please ensure that you cancel or complete the current task or
function and return to the main interface, then power off.
3.2.7. Do not excessive force to operate the touch screen.
3.2.8. During long period of non-use, please disconnect the power and turn off the X100 PAD2 unit.
4.Special function and Diagnosis
4.1. Menu Options
4.1.1. After the X100 PAD2 mainframe is connected to the vehicle via main test cable, Immobilization
can be performed. The Immobilization interface is shown as below:

4.1.2. X100 PAD2 lists mileage adjustment separately. The Odometer Adjustment interface is shown as
below:
.
4.1.3. 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.

4.1.4. Besides the usual system diagnostic functions, XTOOL also has developed a series of special
diagnostic functions for certain vehicles as follows:
4.2. Test Functions: it can check 4 systems for the vehicles (Engine, ABS, Airbag, BCM)
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.

X100 PAD2 Diagnosis System
12
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.

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

X100 PAD2 Diagnosis System
14
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.

X100 PAD2 Diagnosis System

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.
