3.2. Precautions before Use
3.2.1. The vehicle power supply has to meet the normal voltage limits DC4.8V---5V.
3.2.2. When pull and plug test wire harness, users should pinch the front-end of the
wire harness to pull and plug, not pull the middle section of the wire harness. Users
should check the corresponding direction of the port and plug in horizontally when
they plug the wire harness, instead of inserting in an oblique way, which may
damage the terminal.
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. The ECU for domestic vehicle models in China are relatively disorderly, so
when users meet conditions, such as the car can not be tested or the test data is
wrong, they should consider whether the selected menu corresponds to the tested
electronic control system, or they can find the car ECU and select the right menu
according to the model number on the ECU label.
3.2.5. If users can not find the tested vehicle model or electronic control system on
PS70PRO test menu, they may need to update the software or consult Xtool
technical service department.
3.2.6. Do not to have connection test by using harness not from Xtool to avoid
unnecessary losses.
3.2.7. Do not take power off directly in the communication between PS70PRO and vehicle.
Users should cancel the task and return to the main interface, then power off.
3.2.8. The device should be put and lifted slightly to avoid collision when using
PS70PRO. When click the screen, touch it gently to guarantee the service life of the
touch screen.
3.2.9. During long period of non-use, please disconnect the power and turn it off.

4.1.1. After PS70PRO tablet connected to vehicle via main cable, diagnosis can be
performed now. The diagnostic interface comes up as below.
4.1.2. Users can choose menu based on their actual needs: 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 enteringChinese cars menu. Users also caninput vehicle model to search.

4.2. Test Functions
4.2.1. Take Volkswagen car for example, select Diagnosis, then select Europe Car,
users can see Volkswagen’s VW word. If the VW word 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:
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 data 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

PS70PRO Diagnosis System

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 and 105℃, what
are the operating voltage and time of each sensor and actuator?
Special Functions: depends on vehicle models.
Actuation/Active/ Components Test: mainly to judge whether these actuating
components of engine are working properly.

4.3. 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, shown as below.

PS70PRO Diagnosis System
13
4.4. Read DTCs
Select Read Fault 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.
4.5. Clear DTCs
4.5.1. 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.

PS70PRO Diagnosis System
14
4.5.2. 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.
4.6. 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.

PS70PRO Diagnosis System
15
Tips: Live Data is the important function for maintenance technicians further diagnose
the troubles. This function needs maintenance technicians to be 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. (The
following is test conditions and typical values of common live data)

4.7. Special Functions
More special functions will be found in different vehicle models.
4.8. Actuation/Active/Components Test
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.

4.8.1. 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.
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.
