3.2. Precautions Before Use
3.2.1. The vehicle power supply has to meet the normal voltage limits DC 9-12V
3.2.2. Users should check the position of the DLC port and ensure the OBD 16
connector and the DLC port are correctly aligned before attempting to connect.
3.2.3. When carrying out some special functions tests, users are required to operate
the device according to operating instructions. For some tests the vehicle has to
meet certain requirements, for example: engine temperature 80℃/105℃, turn off
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 PS90 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 use excessive force to operate the touch screen.
3.2.8. During long period of non-use, please disconnect the power and turn off the
PS90 unit.
4.Diagnosis
4.1. Menu Options
4.1.1. After the VCI box is connected to the vehicle and paired with PS90 mainframe
via wired or wireless connection, diagnosis can be performed. The diagnostic
interface is as shown below:

PS90 Diagnosis System

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 word. If the word 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.

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:

PS90 Diagnosis System
11
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:

PS90 Diagnosis System
12
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.

Different vehicle makes and models will have different special functions available.
4.8. Actuation/Active Components Test
Test Conditions: Ignition On engine Off.
If the engine is started or an engine rotation speed signal is received, component
actuation will be interrupted.
In the process of actuating components, a single component will always be in the
trigger status until the next component is activated.
Actuating components can be checked by hearing or touching.
