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)
