⚫Precautions for Diagnosis
1. The voltage range on the car: +9~+18V DC;
 Note: Please make sure all the cables are connected tightly; The vehicle’s DLC is not always located under
the dash; for the location of the DLC, please refer to the vehicle’s user manual.

8
2. When testing some special functions, the operator must operate according to the prompts and meet the test conditions.
For some models [special functions], the conditions that need to be met are: engine water temperature 80 ℃~105 ℃, turn
off headlights and air conditioners, keep the accelerator pedal in the released position, etc.;
3. The electronic control systems of differentmodels are very complicated. If you encounter situations where it is impossible
to test or a large amount of test data is abnormal, you can search for the ECU of the vehicle and select the menu for the
model on the ECU nameplate;
4. If the vehicle type or electronic control system to be tested is not found in the diagnostic function, please upgrade the
vehicle diagnostic software to the latestversion using the Updates menu or consult the XTOOL technical servicedepartment;
5. Only wiring harnesses provided by XTOOL and designed for the scan tool are permitted to be used with this scan tool to
avoid damage to the vehicle or the scan tool;
6. When running a Diagnostics function, it is forbidden to shut down the scan tool directly. You should cancel the task before
returning to the main interface and then shutting down the scan tool.
BEGINNING DIAGNOSTIC TESTING
After the tablet device is properly connected to the vehicle, you could start the vehicle diagnosis.
VEHICLE SELECTION
The scan tool supports the following 3 ways to access the smart diagnostics system.
⚫AUTO SCAN
⚫MANUAL INPUT
⚫SELECT VEHICLE BY AREA
Click the VIN button in the upper left corner and then choose to enter the vehicle diagnosis through either AUTO SCAN or
MANUAL INPUT.
AUTO SCAN: It supports the automatic reading of vehicle VIN code. You also can tap on the button “AUTO SCAN” on the
diagnosis system entrance to use this function. Please make sure that the car and the device are well connected before
using this function.
 If your model is not recognized, please try the following steps:
① UPDATE all software, and check whether the APP is updated in [Settings]

9
② Please click Diagnosis on the main menu to enter the selection menu, manually select the engine system to
read the ECU information, and confirm whether the VIN can be read.
③ Contact the XTOOL technical team to provide the VIN code to confirm whether the model supports automatic
identification of VIN.
MANUAL ENTER: It supports manual input of car VIN code. When entering the VIN code manually, make sure that the 17
characters entered are correct to ensure accurate test results.
⚫SELECT VEHICLE BY AREA
In addition to the above 3 methods, you can also choose a car brand by selecting the appropriate region at the top of the
screen. You can select the vehicle model that needs to be diagnosed according to the area, as shown below:
OBD-II supports reading the related fault codes of the Powertrain Control Module (PCM);
DEMO, a demonstration program; Click this button to experience and learn the operation processes of the diagnostic
function
Some models provide multiple entry methods in the sub-menu, including:
⚫Automatic Detection
⚫Manual Selection
⚫System Selection

10
Automatic Detection will automatically identify the vehicle's VIN code, and then read the information of your target
diagnostic object. If you choose "Manual selection", then you can continue to select the vehicle brand, year, and model of
the vehicle in the sub-menu to diagnose the vehicle. Enter "System Selection", you can also diagnose the vehicle according
to the system according to your needs after selecting the model.
DIAGNOSIS FUNCTIONS
Diagnostics functions supported by the scan tool are listed below:
⚫Read ECU Information
⚫Read/Clear Trouble Code
⚫Read Live Data
⚫Freeze Frame
⚫Actuation Test (Bi-Directional Control)
⚫Special functions
⚫READ ECU INFORMATION
This function is to read ECU version information and is the equivalent of "System Identification" or "System Information”
in some electroniccontrol systems. These equivalent termsall refer to reading ECU-related software and hardware versions,
models and production date of diesel engines, part numbers, etc. This information is helpful when recording maintenance
records and ordering new parts

11
⚫READ TROUBLE CODE
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 troubles are mechanical system troubles or
executive circuit troubles. It is also possible that the signal of a sensor may be inaccurate but within limits, which can be
examined using Live Data.
⚫CLEAR TROUBLE CODE
It allows for clearing current and historical trouble codes stored in the ECU memory, under the premise that all the troubles
have been resolved.
Some troubles are immediately detected by the ECU with the key in the run position and without the engine running. Other
troubles are not detected until very specific test conditions are met such as engine coolant temperature within a range,
speed within a range for a duration of time, throttle percentage within a range, etc.

12
If the trouble codes are erased when the trouble remains unresolved, the trouble code will reappear in the ECU the next
time the ECU performs the specific diagnostic test for that trouble.
If the trouble is resolved but there is a stored trouble code, sometimes the ECU will detect the resolution and clear the
trouble code or more likely, classify it as “historical” trouble.
If the trouble is resolved and the user clears the trouble codes, the trouble history will be cleared.
If the user intends to have another colleague or mechanic investigate the problem, it is not recommended for the user to
clear the trouble code since doing so may erase information helpful to others who may investigate the issue.
DTC Status
Descriptions
Suggestions
Current /Present
Current DTC’s are trouble codes that are stored in the
ECU when both continuous and non-continuous (2 trip)
monitors fail. Current DTC’s command the MIL On the
instant they are stored in the ECU.
Current DTC’s can be cleared using the
Clear DTC’s function of the Scantool, or
when the ECU monitor (2 trip monitor) has
ran and completed 40 consecutive trips
without a fault.
History/Stored
History DTC’s are trouble codes stored in the ECU
when continuous and non-continuous monitors (2nd
trip) fail. History DTC’s set in conjunction with Current
DTC’s and are not cleared by the ECU monitor. History
DTC’s can only be cleared using the Clear DTC function
of the Scantool.
History DTC’s set in conjunction with
Current DTC’s and are not cleared by the
ECU monitor. History DTC’s can only be
cleared using the Clear DTC function of
the Scantool.
Pending
Pending codes are codes that prep themselves when
they determine a fault that engine cycle. They are
basically a preliminary investigation for your engine. To
simplify, a random malfunction can occur during the
current drive cycle but only happen for a split second.
This will cause the malfunction to throw a “pending
code”.
Typically pending codes are not to severe
but you shouldn’t ignore them either, it can
be cleared using the Clear DTC’s function
of the Scantool
Permanent
Permanent DTC’s are trouble codes that are stored in
the ECU when continuous and non-continuous
monitors fail. Permanent DTC’s are set in conjunction
with Current and History DTC’s.
Permanent DTC’s cannot be cleared using
the Clear DTC’s function on the Scantool.
Instead, Permanent DTC’s are cleared
when the ECU monitor completes and
passes three consecutive trips.
For Volkswagen
Active/static
Active/Static means that the fault is happening at the
moment and can/should be take care of.
The fault cannot be cleared directly by
using the Clear DTC’s function of the
diagnostic tool and the internal fault of the
car must be eliminated manually
Passive/sporadic
It is a fault that has occurred in the past and can be
cleared by Scantool, and user should to check if the
DTC will appear again.
/
⚫READ LIVE DATA
Real-time information about various sensors is called “Live Data”. Live Data includes parameter identifications (PIDs) of
the running engine such as oil pressure, temperature, engine speed, fuel oil temperature, coolant temperature, intake air
temperature, etc. Based on these parameters, we can predict directly where the problem lies, which helps to narrow the
scope of maintenance. For some vehicles, during their actual operation, the problems such as performance characteristics
or sensitivity reduction, can be evaluated using live data.

13
Click the magnifying glass on the top right, you can search for related PIDs based on keywords
⚫Custom
The scan tool includes support to select and show multiple PIDs. Click Display All to display all PIDs
⚫Combine
The scan tool includes support to select multiple PIDs and click Combine to combine different graphs into one chart.

14
⚫Data recording
The scan tool supports recording the current data values in the form of text. You can view the recorded files in
Reports->Data Replay.
⚫Pause
Click this button to pause the recording timeline
⚫FREEZE FRAME
When the signal of the sensor is abnormal, the ECU will save the data at that moment of failure to form a freeze-frame. It is
usually used to analyze the reasons that may lead to component(?) failures.

15
The live data items supported by vehicles of different brands are not the same, so the freeze frames displayed when
diagnosing vehicles of different brands may also be different. Some vehicles may not have the option of a freeze-frame
which means that the model does not support this function.
Take Renault Duster ii ph as an example. After selecting the system to enter the lower freeze frame menu, the device will
list all the fault codes under the system.
Users can click on a fault code, such as DF1068 to view the freeze frame recorded by the car when the fault code occurs,
including context when the fault appeared, and current context and additional data.
Context when fault appeared: record the live data when fault appeared to help the user to know the vehicle status. *Some
vehicles don't support this function; users will get a prompt when they click the menu.
Current context: Displays the current live data stream associated with the DTC
Additional data: record other data related to the fault

16
⚫ACTUATION TEST (BI-DIRECTIONAL CONTROL)
Actuation test, also known as bidirectional control, is a generic term used to describe sending and receiving information
between one device and another. This function is used mainly to judge whether these actuating components of the engine
are working properly.
The vehicle engineers responsible for designing computer control systems programmed them so a scan tool could request
information or command a module to perform specific tests and functions. Some manufacturers refer to bidirectional controls
as functional tests, actuator tests, inspection tests, system tests or the like. Reinitialization and reprogramming also can be
included in the list of bidirectional controls.
This function allows the device to send information to and receive information from, vehicle control modules. For example,
in the case of OBD II generic information Mode 1 (which relates to data parameters), the scan tool user initiates a request
for information from the powertrain control module (PCM), and the PCM responds by sending the information back to the
scan tool for display. Most enhanced scan tools also can actuate relays, injectors and coils, perform system tests, etc. Users
could check the individual part to see what is working properly by actuation test.
⚫SPECIAL FUNCTIONS
Usually, special functions provide various reset or re-learning functions menus for most vehicle systems. You can easily and
quickly solve some faults through special functions for your car. After some functions are successfully executed, fault codes
will be generated, which need to be cleared manually after the car is running for a little while which could include a single
start of the engine or multiple warm up cycles.
And under each system, you can view the special features supported by that system. Different models and systems often
have different special functions. Even for the same system of the same model, the years and ECU type may lead to different
special functions supported.
3. SPECIAL FUNCTIONS
The Scan Tool supports a lot of commonly used special reset functions, allowing you to quickly access your vehicle system
for various scheduled services, maintenance, and reset performance. These functions often eliminate the need to reset
codes after resolving common problems. Since XTOOL is continuously developing, the manual may not include all of the
latest special functions that are available for download. This user manual lists some of the commonly used special reset
services for your reference.
5.1 ABS BLEEDING
Anti-Lock Braking System keeps the tires from locking up immediately when there are brakes. Keeping ABS in good
condition can give full play to the effectiveness of the brakes, shorten the braking time and distance, prevent the vehicle
from skidding and tailing during emergency braking, ensure good driving stability and steering maneuverability, and avoid
violent friction between the tires and the ground to reduce tire wear. When the ABS contains air, the ABS bleeding function
must be performed to bleed the brake system to restore ABS brake sensitivity.
ABS Bleeding can be performed in the following cases:
⚫replace the rear brake distributor pump or the front brake distributor pump. 2.
⚫Severe brake fluid shortage
⚫change the brake fluid
The operation guidelines of the ABS Bleeding function are shown as below:
1. Read the operating instructions and precautions that appear on the screen carefully before performing the operation
to ensure that the equipment and car are in the correct condition
2. Attach bleeder bottle to the left rear bleeder screw.
3. Open the left rear bleeder screw.

17
4. When ready, click "OK" to enter the bleed procedure, and pumping the brake pedal continuously with steady applies
every 2 seconds during the entire procedure

18
5. Continue pumping the brake pedal, when air bubbles are no longer visible, select OK to enter next bleed procedure
for left front wheel
6. Repeat the operation 3 times to complete the bleed procedure for the left front wheel, right front wheel and right rear
wheel in turn.
7. Stop pumping the brake pedal, and close the right rear bleeder screw
8. Click OK to complete the entire bleed procedure
