About Hardware
Question: After DFPV Diag. 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 can not 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.
Question: There is no character on the backlit
screen. What should I do?
Answer: Check if the power is well connected.
Turn off the machine, unplug the power
connector and re-plug it. Turn on the machine
after it has been connected to the power for 1
second.
Question: Why can’t the diagnostic program be
downloaded to SMARTBOX?
Answer: Please make sure that the
SMARTBOX is well connected with DFPV Diag.
main unit.
Question: Why does DFPV Diag. fail in
communication with ECU?
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?
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.
