Precautions on Using this tool
Before using this tool, please read the following safety information carefully.
 Always perform automotive testing in a safe environment.
 If the VCI (Vehicle Communication Interface) device is not in use for a long
period of time, it is suggested to unplug the connector from vehicle’s DLC to
conserve battery power.
 Wear an ANSI-approved eye shield when testing or repairing vehicles.
 The vehicle shall be tested in a well-ventilated work area, as engines produce
various poisonous compounds (hydrocarbon, carbon monoxide, nitrogen
oxides, etc.)
 Do not connect or disconnect any test equipment while the ignition is on or
the engine is running.
 Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
 Keep the tool dry, clean, free from oil, water or grease. Use a mild detergent
on a clean cloth to clear the outside of the equipment as necessary.
 Do not drive the vehicle and operate the tool at the same time. Any distraction
may cause an accident.
 Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
hot engine parts.
 Before starting the engine, put the gear lever in the Neutral position (for

LAUNCH X-431 PRO3 SE User Manual

Precautions on Operating Vehicle’s ECU
 Do not disconnect battery or any wiring cables in the vehicle when the ignition
switch is on, as this could avoid damage to the sensors or the ECU.
 Do not place any magnetic objects near the ECU. Disconnect the power
supply to the ECU before performing any welding operations on the vehicle.
 Use extreme caution when performing any operations near the ECU or
sensors. Ground yourself when you disassemble PROM, otherwise ECU and
sensors can be damaged by static electricity.
 When reconnecting the ECU harness connector, be sure it is attached firmly,
otherwise electronic elements, such as ICs inside the ECU, can be damaged.
