6. FAQ
X-431IV 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.
Here we list some frequently asked questions
and answers relating to X-431IV.
6.1 About Update via Internet
Question: “Removable Disk” icon does not
appear in the catalogue of “My computer” after
the CF card reader/writer is connected to the
USB port of computer. Why?
Answer:
Possible cause: there may not be driver for CF
card reader/writer 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.
Solution: Check if there is the driver for CF
card reader/writer 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/writer.
When the CF card reader/writer 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: Some downloaded diagnostic
program is not listed in the update tool, what is
the reason?
Answer: There are two possible causes:
put in the same folder as other diagnostic
programs. Please move it to the same folder as
others.
2. The diagnostic program is not fully
downloaded. Please download the program
again.
Question: When the updated software is used
in vehicle diagnosis, some diagnostic program
cannot be downloaded successfully from the
CF card. Why?
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.
Question: Why can’t the main unit recognize
the replaced CF card?
Answer: There are two possible causes:
1. The original 32M CF card has not been fully
copied. Please delete the incomplete file and
copy again.
2. The CF card reader/writer is not compatible
with the CF card. Monofunctional CF card
reader/writer is better in such situation.
Question: How to make a new X-431IV CF
card when the data in old one is lost or
damaged?
Answer: In case X-431IV CF card is damaged
and the program in the card cannot be used,

6.2 About Hardware
Question: After X-431IV downloads the
diagnostic program from the CF card it prompts
“Please contact your local dealer”. What is the
reason?
Answer: It is because the license No. in CF
card does not match the SMARTBOX. It can be
solved in the following way:
1. Download the software that is corresponding
to the SMARTBOX so that the CF card can
match the SMARTBOX.
2. Use the UPDATE TOOL that is provided on
http: // www.X431.com for update. Never use
WINZIP or other decompressing tool for update.
Question: Why does the LCD screen respond
so slowly?
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: Power cannot be turned on with the
power button on the main unit after the machine
is connected to vehicle diagnostic socket
through cables and connectors. What can I do?
Answer: Check the power pin of vehicle
diagnostic socket with multimeter for power.
The power pin in diagnostic socket varies from
one vehicle to another. Please refer to the
User’s Manual of specific vehicle diagnostic
program to find the power pin. If there is no
power supply from the diagnostic socket,
please get power in other ways, such as from
battery or cigarette lighter.

communication with ECU?
Answer: Please make sure that the diagnostic
connector and diagnostic program are matching
vehicle make.

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.
Question: Why does the system prompt that no
CF card is found when the machine is turned
on?
Answer: The possible cause is that no CF card
is in the machine, or CF card is inserted
improperly or damaged. If it is damaged, it is
necessary to make a new one.

Each character or digit has a particular
purpose. They are as follows:
First vehicle identification number digit
identifies the country from which the vehicle
was manufactured. For example, U.S.A. (1
or 4), Canada (2), Mexico (3), Japan (J),
Korea (K), England (S), Germany (W), Italy
(Z).
Second vehicle identification number digit
specifies the manufacturer. Audi (A), BMW
(B), Buick (4), Cadillac (6), Chevrolet (1),
Chrysler (C), Dodge (B), Ford (F), GM
Canada (7), General Motors (G), Honda (H),
Jaguar (A), Lincoln (L), Mercedes Benz (D),
Mercury (M), Nissan (N), Oldsmobile (3),
Pontiac (2 or 5), Plymouth (P), Saturn (8),
Toyota (T), Volvo (V).
Third vehicle identification number digit
indicates the vehicle type or manufacturing
division.
Fourth through eighth vehicle identification
number digit reveals the vehicle features
such as body style, engine type, model,
series, etc.
The ninth vehicle identification number digit
is a VIN accuracy check digit, verifying the
previous VIN numbers. This is how the
check digit works:
♦ STEP 1
Assign to each number in the VIN its
actual mathematical value and assign to
each letter the value specified for it in the
following chart:
Add the products from steps 1 and 2 and
divide the total by 11.
♦
STEP 4
The numerical remainder is the check
digit, which would appear in the 9th
position in the VIN. If the remainder is 10,
then the letter "X" is used for the check
digit.
identification number digits indicate the
sequence of the vehicle for production as it
rolled of the manufacturers’ assembly line.
Your VIN can be used to track recalls,
registrations, warranty claims, thefts and
insurance coverage.
Common locations of the vehicle identification
number (VIN) vary but the following are places
to look:
Firewall of the vehicle
Left hand inner wheel arch
Steering column
Radiator Support Bracket
Dash by windshield
