Notes and Important Messages
Notes
A NOTE provides helpful information such as additional explanations, tips, and
comments.
Example:
Note: Remember to remove the VCI connector from the vehicle’s DLC after use.
Warning
Warning indicates a hazardous situation which, if not avoided, could result in
minor or moderate injury to the operator or to bystanders.
Example:
Warning: Retrieving and using DTCs for troubleshooting vehicle operation is only
one part of an overall diagnostic strategy. Never replace a part based only on the DTC
definition. Each DTC has a set of testing procedures, instructions and flow charts that
must be followed to confirm the location of the problem. This information can be found
in the vehicle’s service manual.
Danger
Danger indicates an imminently or potentially hazardous situation which, if not
avoided, could result in death or serious injury to the operator or to bystanders.
Example:
Danger: If you must drive the vehicle in order to perform a troubleshooting
procedure, always have a second person help you. Trying to drive and operate the
diagnostic tool at the same time is dangerous, and could cause a serious traffic accident.

Important Safety Precautions
To avoid personal injury, property damage, or accidental damage to the product,
read all of the information in this section before using the tool.
DANGER
• When an engine is operating, keep the service area well-ventilated or attach
a building exhaust removal system to the engine exhaust system. Engines
produce various poisonous compounds (hydrocarbon, carbon monoxide,
nitrogen oxides, etc.) that cause slower reaction time and result in death or
serious personal injury.
• Please use the included battery and power adaptor. Risk of explosion if the
battery is replaced with an incorrect type.
• DO NOT attempt to operate the tool while driving the vehicle. Have second
personal operate the tool. Any distraction may cause an accident.
WARNING
 Always perform automotive testing in a safe environment.
 Do not connect or disconnect any test equipment while the ignition is on or
the engine is running.
 Before starting the engine, put the gear lever in the Neutral position (for
manual transmission) or in the Park (for automatic transmission) position to
avoid injury.
 NEVER smoke or allow a spark or flame in vicinity of battery or engine. Do
not operate the tool in explosive atmospheres, such as in the presence of
flammable liquids, gases, or heavy dust.
 Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
 Wear an ANSI-approved eye shield when testing or repairing vehicles.
 Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
 Use extreme caution when working around the ignition coil, distributor cap,

LAUNCH X-431 PRO5 User Manual
iv
ignition wires and spark plugs. These components create hazardous voltage
when the engine is running.
 To avoid damaging the tool or generating false data, please make sure the
vehicle battery is fully charged and the connection to the vehicle DLC (Data
Link Connector) is clear and secure.
 Automotive batteries contain sulfuric acid that is harmful to skin. In operation,
direct contact with the automotive batteries should be avoided. Keep the
ignition sources away from the battery at all times.
 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 when necessary.
 Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
hot engine parts.
 Store the tool and accessories in a locked area out of the reach of children.
 Do not use the tool while standing in water.
 Do not expose the tool or power adapter to rain or wet conditions. Water
entering the tool or power adaptor increases the risk of electric shock.
 This tool is a sealed unit. There are no end-user serviceable parts inside. All
internal repairs must be done by an authorized repair facility or qualified
technician. If there is any inquiry, please contact the dealer.
 Keep the tool far away from magnetic devices because its radiations can
damage the screen and erase the data stored on the tool.
 Do not attempt to replace the internal rechargeable lithium battery. Contact
the dealer for factory replacement.
 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.
