FAQ
X-431TOOL is a hi-tech product. With the
development of modern automotive industry,
more and more new technology will be adopted
and there may be questions during operation.
Read the user’s manual to get the answer
whenever you have any question, or contact
our Customer Service Center for help.
Question: When the updated software is used
in vehicle diagnosis, some diagnostic program
can not be downloaded successfully from the
CF card. Why?
Here we list some frequently asked questions
and answers relating to X-431TOOL.
Answer: possible causes and solutions:
1. The Display Program may have not been
updated. Please update the Display Program.
2. The diagnostic program for the vehicle make
is damaged. Please re-download the diagnostic
program and update.
About Update via Internet
Question: “Removable Disk” icon does not
appear in the catalogue of “My computer” after
the CF card reader is connected to the USB
port of computer. Why?
Question: Why can’t the main unit recognize
the replaced CF card?
Answer:
Possible cause: there may not be driver for CF
card reader in the computer. The default driver
is with the operating systems like Windows
Me/2000/XP, Mac OS 9.x/Mac OS X and Linux
2.4.X. However, there is no such default driver
with Windows 98.
Answer: There are two possible causes:
1. The original CF card has not been fully
copied. Please delete the incomplete file and
copy again.
2. The CF card reader is not compatible with
the CF card. Monofunctional CF card reader is
better in such situation.
Solution: Check if there is the driver for CF
card reader in the computer. If the computer
uses Windows 98 operating system, it is
necessary to install the driver into computer by
using the CD-ROM provided with CF card
reader.
Question: How to make a new X-431TOOL CF
card when the data in old one is lost or
damaged?
Answer: In case X-431TOOL CF card is
damaged and the program in the card can not
be used, please use the following procedure to
make a new CF card:
When the CF card reader driver is installed
successfully, a “Removable disk” icon will
appear in the catalogue of “My computer”.
Usually it is listed after original disk drive. For
example, if there were drives A, B, C and D
originally, the removable disk will be “E”. If there
were drives A, B, C, D and E originally, the
removable disk will be “F”. The rest may be
deduced by analogy.

Question: Why can’t the diagnostic program be
downloaded to DIAGBOX?
About Hardware
Question: After X-431TOOL downloads the
diagnostic program from the CF card, it prompts
“Please contact your local dealer”. What is the
reason?
Answer: Please make sure that the DIAGBOX
is well connected with X-431TOOL main unit.
Question: Why does X-431TOOL fail in
communication with ECU?
Answer: It is because the license No. in CF
card does not match the DIAGBOX. It can be
solved in the following way:
1. Download the software that is corresponding
to the DIAGBOX so that the CF card can match
the DIAGBOX.
2. Use the UPDATE TOOL that is provided on
http: // www. X431.com for update. Never use
WINZIP or other decompressing tool for update.
Answer: Please make sure that the diagnostic
connector and diagnostic program are matching
vehicle make.
Question: The screen keeps blank after
flashing when the machine is turned on. What
should I do?
Question: Why does the LCD screen respond
so slowly?
Answer: Take out the CF card and re-start the
machine to see if there is normal display. If the
display is normal when the CF card is taken out,
the CF card should be replaced. If the screen is
still blank, please contact the local service
engineer.
Answer: It is because the ambient temperature
is close to the lower limit of operating
temperature range (0-50℃). In this situation, it
is necessary to warm up the machine for 20
minutes before test.
Question: Why does the system prompt that no
CF card is found when the machine is turned

About ECU
In the last two decades, we have seen more
and more extensive application of IT and
electronic technologies in modern vehicles.
Many vehicle control systems, typically EFI
(Electronic Fuel Injection), ABS (Anti-block
Braking System), SRS (Air Bag), TC (Traction
Control), AT (Automatic Transmission), etc., are
computerized. Computerization makes the
control precisely, quickly, effectively and safely.
Consequently, a significant progress in vehicle
driveability, fuel economy, power performance,
comfortability, emissions, safety and so on has
been made.
Fig 6-1
Composition
and
Working
Principle of Computer- Control
System
Sensor
It is a device that converts non-electric variable
into electric signal. More than 50 types of
sensor are used in modern vehicles, most of
which are found in powertrain, chassis control
systems, body control system, safety system,
etc.
The Computer Control System consists of the
on-board computer, and several related control
devices (sensors, switches, and actuators).
Most on-board computers are located inside the
vehicle behind the dashboard, under the
passenger’s or driver’s seat, or behind the right
kick panel. Some manufacturers may still
position it in the engine compartment. The
sensors, switches, and actuators are devices
such as oxygen sensors, coolant temperature
sensors, throttle position sensors, fuel injectors,
etc., that are located throughout the engine,
and are connected by electrical wiring to the
on-board computer. As an example, the
diagram of engine control system is shown in
Fig 6-1.
According to the physical variables controlled,
sensors are sorted into following types:
temperature sensor, pressure sensor, air flow
sensor,
position/angular
sensor,
gas
concentration sensor, rotary speed sensor,
acceleration sensor, vibration sensor, light
sensor, distance sensor, electrical current
sensor, angular speed sensor, shaft sensor,
liquid level sensor, etc.
The commonly-used sensors in corresponding
control systems of vehicle are:
1) In engine management system: intake air
pressure (or air flow), air/fuel ratio,
crankshaft position, knock, RPM, intake air
temperature, coolant temperature and O2
sensors.
2) In transmission system: vehicle speed,
throttle position, RPM, A/T output shaft
speed, toque, oil pressure/temperature,
shift position sensors.

X-431Tool User’s Manual
3) In braking system: vehicle speed, wheel
speed, deceleration, sliding rate, braking
pedal force, braking pedal position sensors,
etc.
into electrical parameter.
2) A/D converter: it converts the analogue
signal from the sensor into digital signal.
Then the digital signal can get into SMC.
4) In steering control system: steering, vehicle
acceleration, vehicle speed sensors, etc.
3) SMC: it consists of I/O interface, CPU,
RAM/ROM, etc. The received digital signal
is computed here with the pre-programmed
parameters from ROM. The computed
result is transmitted through I/O interface to
the output circuit, and then to the
corresponding actuators.
5) In suspension system: vehicle speed,
vehicle height, steering angle, throttle
position, braking force sensors, etc.
6) In A/C system: external temperature,
internal temperature, sunshine, coolant
temperature, refrigerant pressure and
humidity sensors, etc.
The data in ROM is written by manufacturer
and will not be lost when power is off.
However, the data in RAM will be lost when
power is off.
7) In instrument, alarm and diagnosis systems:
remaining fuel, coolant temperature, oil
pressure, oil status, intake air pressure,
windshield washer fluid level, battery liquid
level, door lock, braking fluid level sensors.
4) Output circuit: it is to amplify the signal from
SMC. The weak current from SMC is not
able to activate the actuator. So it has to be
amplified.
ECU
The electronic control unit is composed of input
circuit, A/D converter, SMC, output circuit, etc.
See Fig 6-2.
Actuator
Actuator is to convert the electrical signal into
force or displacement. The popular actuators
are listed below:
1) Solenoid valve: This actuator is to convert
electrical signal into linear movement. Two
types of solenoid valves are used in the
vehicle. One is directly driven with linkage,
e.g. the magnetic switch of starter motor.
The other is for controlling pressure and
flow by transferring the movement to
relevant valves. For example, in engine
intake air control, electronically controlled
automatic transmission, suspension control,
etc.

2) Motor: DC motor is the most popular
actuator used in automobile. It can be
divided into two types according to its use.
One is rotated by power, e.g. windshield
wiper, seat adjuster, etc. The other is used
in servo mechanism. In this situation,
external force makes the rotor rotate
around the stator, e.g. the servo motor for
1) Input circuit: digital signal from sensor will
enter the CPU directly. However, the
analogue signal will be treated in the A/D
converter before getting into CPU. The
input circuit filters out the noise, converts

damper.
0.3-0.4V. If not, the situation will be deemed as
fault and fault code will be stored in memory.
Self-diagnosis system can detect damaged
sensor, or short/open circuit, but it can not
appraise the performance of sensor. Occasional
occurrence of abnormal signal will not be
deemed as fault immediately. For not being
interrupted by the sensor fault, the engine will
be controlled by the pre-stored normal coolant
temperature (e.g. 80℃) from the self-diagnosis
system.
Besides the two types listed above, there are
other types, such as relay, electronic switch,
etc.
Self-diagnosis
Control System
of
Electronic
All modern cars are controlled by an Electronic
Control Unit (ECU). The main purpose of the
electronic control system is to provide
maximum engine performance with the least
amount of air pollution and the best fuel
efficiency possible. However, the complexity of
the system may increase the difficulty for its
troubleshooting. The function of self-diagnosis
is for solving such problem with electronic
control system.
2) For actuator
When the engine is running, ECU sends
commands to actuators according to the
practical situation. If the actuator can not work
normally, the monitoring circuit will transmit the
message to the ECU. ECU can make the
message displayed and take measures to
ensure the safe running of engine. For example,
when the power tube in engine ignition system
is out of order, the ignition monitoring circuit
sends feedback to the ECU. ECU emits
warning signal and sends commands to
actuator for stopping injection so as to prevent
the unburnt mixture from damaging the catalytic
converter of exhaust system.
Working Principle of Self-diagnosis
The composition of self-diagnosis system is
similar to electronic control system. The basic
component is electronic control unit. The main
purpose of self-diagnosis system is to diagnose
the sensors, actuators, circuits and ECU in
vehicle.
3) For ECU
There is no monitoring circuit, but a monitoring
clock in the ECU for resetting ECU regularly. If
ECU is out of order, its program will not be run
and the clock will not reset the ECU so that
overflow may occur. This situation is deemed as
fault for displaying.
The computer assigns a numeric code for each
specific problem that it detects, and stores
these codes in its memory for later retrieval,
and turns on the fault indicator on the dash
panel to warn the driver. The problem detected
may be: inputted/outputted signal exceeds the
specified range, or some circuit is
short-circuited or open.
For preventing unexpected stopping of vehicle
caused by problem with ECU, there is a backup
circuit in ECU. When the backup circuit
receives the signal of abnormality from the
monitoring circuit, a spare control program will
be started for keeping the engine running as
pre-programmed.
Now let’s take gasoline injection control system
as an example to describe the working principle
of the self-diagnosis system. When problem
occurs, the process of diagnosis and treatment
will be as follows:
1) For sensor
If the output signal from the sensor is out of the
specified range of voltage when engine is
running, it will be deemed as fault. For example,
the normal output voltage from coolant
temperature sensor should be in the range of

system or external scan tool.
sensor into digital signal needed by CPU.
The on board diagnostic system in different
vehicle may indicate the fault in different way. In
general, the following ways are popular:
2. CPU
The digital signal is transferred to CPU for
computation and logical operation so that
correct air/fuel mixture can be obtained. CPU
can also compute ignition timing and idle speed,
and control exhaust, fuel and diagnostic
systems.
1) Blinking of fault indicators on the instrument
panel
2) Swing of multimeter index
3) Blinking of red/green LED on ECU
4) Shown by a special device
3. Power source
The reference output signal (5V) of ECU and
the 12V voltage for control module are from
vehicle battery. Memory is also dependent on
the power supplied by the battery.
The more intuitionistic way for showing the fault
is by external scan tool.
The diagnostic system of modern cars is
equipped with diagnostic socket or DLC (data
link connector). Fault code in vehicle ECU can
be read out by connecting a scan tool to the
diagnostic socket. In early time, each vehicle
system had its own type of diagnostic socket.
Since 1996, SAE has specified a uniform
system called OBDII on board diagnostic
system. Each vehicle that is made in
accordance with the system may have the
same diagnostic socket, same definition of pin
and same description of fault code. The control
units of every system are connected to bus, so
only one diagnostic socket is needed for
readout of fault code. OBD provides the
possibility of reading data stream and
displaying working status of switches and
actuators. Moreover, external scan tool can
send commands to activate the actuators.
4. Memory
ECU contains three types of memory: ROM,
RAM and PROM (or EEPROM).
1) ROM
ROM stores the programming information
that can only be read by ECU. The program
in ROM is not editable. Power cut will not
damage the data in ROM.
2) RAM
It is for temporarily storing the inputted data,
fault code and computed result. Power cut
will make all information in RAM erased.
3) PROM
Its program is made by manufacturer to suit
the application of transmission, engine,
exhaust control, driveability, rear axle ratio,
etc. PROM is can be detached from ECU
and power cut will not damage the data in
it.
X-431TOOL is such an external scan tool for
vehicle diagnosis. It not only has the diagnostic
function like reading fault code, reading data
stream, actuation test, displaying sensor
waveform, coding control unit, etc., but also has
PDA function.
4) EEPROM
Its function is similar to PROM. The
difference between EEPROM and PROM is
that EEPROM can be re-programmed by
manufacturer with a special device.

connected to ECU because most ECU’s are
operated under low voltage (about 5V).
Whenever you work in the vicinity of ECU or
engine control system, please obey the
following precautions:
1. Never damage the lead or connector.
Prevent them from being grounded or
contacting with an unexpected power source.
2. Never use the electrical test tool that is
powered by 6V battery or over. Strong
current may cause the element in ECU
broken or shorted. For checking the engine
control circuit, only the multimeter with large
internal impedance (over 10MΩ) can be
used.
3. Never try to disassemble or repair ECU if
there are not necessary tools and
information. Any mistake may damage the
component or increase the difficulty for
service station.
4. The spark plug wire must be at least 25.4mm
from any sensor circuit or control circuit.
Some unexpected fault in ECU circuit is
caused by magnetic fields that transmit
wrong signal to ECU. High tension wire or
transformer may interfere with ECU, but the
most common cause for such problem is that
the spark plug is too close to ECU harness.
5. Be careful when moving ECU or working
around ECU. Remember that static electricity
may cause strong electrical shock and
damage ECU.
