1. The CF card is not inserted
2. The CF card is inserted incorrectly.
3. A CF card from another X431 unit may be inserted
4. The CF card may also be damaged. If you insert the CF card correctly and you still
cannot access the diagnostic programs, contact your local dealer for assistance.
Why won’t the unit power on when I have it connected to a vehicle? Shouldn’t the
power button work?
If the unit is not powering up once connected to a vehicle, check the connection between
the vehicle and the X431. Some vehicle connections don’t provide power.
Check the power pin of the vehicle diagnostic socket with a multimeter for power. The
location of this power pin varies from one vehicle to another. Please refer to your repair
information database to find the power pin. If there is no power supply from the diagnostic
socket, use the cigarette lighter attachment for power**.
**WARNING: DO NOT USE THE CIGARETTE LIGHT ATTACHMENT IF THE UNIT IS
ALREADY POWERED UP. YOU CAN DAMAGE THE VEHICLE AS WELL AS THE UNIT!
Why does the system freeze when reading a data stream?
It may be due to a loose connector. Turn off the machine, firmly connect the connector,
and switch the machine back on again.
Upon first glance, it looks as if my tool only has 9 vehicle lines. Are there more
lines? How can I access them from the main screen with the manufacturer’s logos?
It looks as if you only have 9 lines because that’s all that can fit on the screen at one time.
Press the ‘Page Down’ button on the lower right of the touch screen. You can scroll
through all available vehicle lines in this manner.
The Mercedes-Benz 38-pin connector doesn’t fit onto the port under the hood. The
fender gets in the way. How do I fix this issue?
The base of the 38-pin connector swivels to allow access to tight spaces. Grasp the top of
the conector firmly, and twist the stem. This should give you sufficient access to the port.
Purchasing updates
Can I purchase a year’s worth of updates at any time?
Yes.
I ordered an update, but the ‘Download Center’ won’t allow me to download any-
thing. It says “Sale of Unit has not been Recorded”.
If you get this message, contact your local dealer for assistance.
