Precaution on Operation
zThe appliance is a sophisticated electronic device, never have it
clashed when in use.
zMain unit screen may flash at the moment of engine ignition, which
is normal.
zYou may unplug the main unit if the program can not be actuated or
confused screen occurs. Plug again to continue the operation.
zMake sure the appliance is properly connected to the DLC to avoid
communication interruptions.
zDuring operation, keep the screen upward and leveled.
zBe careful when plugging and unplugging the main cable and
diagnostic connector. Tighten the screw before operation to avoid
unexpected disconnecting and/or damage to the port.
zHandle with care. Avoid collision. Unplug the power after operation.
zDo not insert or pull the GDS card when the main unit is powered
on.
zAfter the operation, the stylus shall be inserted into the hole on the
back of the main unit, and put away the cable and connector, etc
accessories to the box to avoid the lost.
zUnplug the power cable by holding the connector, not the cable
itself.

1 Foreword
1.1 Product summary
X-431 GDS is a new generation of sophisticated automotive
diagnostic product with colorful screen and powerful functions
developed by LAUNCH.
It provides an optional function of automotive sensor simulation test.
“Sensor simulation test” function is specially designed to diagnose
and simulate vehicle sensor faults quickly and conveniently,
including "DC voltage simulation", "Constant frequency simulation",
"Predefinition waveform simulation", and "Hand-drawn waveform
simulation".
Vehicle sensors are the signal input devices for electrical control
systems, which can transform all kinds of running parameters, such
as vehicle speed, coolant temperature, engine RPM, air flow, throttle
opening, etc., into the electronic signal for the vehicle computer who
can optimize the engine running status per the above-mentioned
parameters to keep the engine working in a prime status.
Meanwhile, it integrates the functions of automobile multimeter,
which enables users to perform voltage, resistance, frequency test.
(The function utilizes the same hardware device as the sensor
module)
