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 and integrated Automotive
diagnose product with colorful screen and powerful functions developed by
LAUNCH, it provide a optional function of Automotive sensor simulation .test
“Sensor simulation test” function is specially developed to diagnose and
simulate vehicle sensor faults, including "DC voltage simulation", "Fixed
frequency simulation", "Predefined waveform simulation", and
"Hand-drawing waveform simulation", which can help customer to diagnose
and simulate the vehicle sensors quickly and conveniently.
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.
Mean while, it has integrated the functions of Auto Multimeter Users can
perform voltage, resistance, frequency test by just clicking the voltage test,
resistance test, or frequency test. (The function uses the same hardware
device with the sensor module)
