Important Safety Information
Warning: To avoid personal injury, property damage, or accidental damage to the product, read all of the
information in this section before using the product.
Work Area Safety
 Keep work area clean and well lit. Cluttered benches and dark areas may cause accidents.
 Do not connect or disconnect the tool while the ignition is on or the engine is running.
 DO NOT attempt to operate the tool while driving the vehicle. Have a second person to operate the tool.
 Before testing a vehicle, put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual
transmission). Engage the parking brake and chock the tires.
 NEVER smoke or allow a spark or flame in vicinity of battery or engine.
 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 operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or heavy
dust.
 Never leave the vehicle unattended while testing.
 Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
 Use extreme caution when working around the ignition coil, distributor cap, ignition wires and spark plugs. These
components create hazardous voltages when the engine is running.
 Keep bystanders, children and visitors away while operating the tool.
 This product is not a toy. Do not allow children to play with or near this tool.
 Use as intended only. Do not modify.
 Inspect before every use; do not use if parts are loose or damaged.
 Do not place the tool on any unstable surface.
 Handle the tool with care. If the tool is dropped, check for breakage and any other conditions that may affect its
operation.
 Keep the tool dry, clean, free from oil, water or grease. Use a mild detergent on a clean cloth to clean the outside
of the tool when necessary.
 Store the tool and accessories in a locked area out of the reach of children.
 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.
 If the VCI (Vehicle Communication Interface) is not in use for a long period of time, it is suggested to unplug the
VCI from vehicle’s DLC to conserve battery power.
Electrical Safety
 Do not use the tool while standing in water.
 Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators.
 Do not expose the tool or power adaptor to rain or wet conditions. Water entering the tool or power adaptor
increases the risk of electric shock.
Personal Safety

Wear an ANSI-approved eye shield when testing or repairing vehicles.
 Do not wear loose clothing or jewelry. Keep hair, clothing, hands, tools, and test equipment away from moving or
hot engine parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
 Do not use the tool while tired or under the influence of drugs, alcohol, or medications. A moment of interruption
can result in serious personal injury.
 People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity
to heart pacemaker could cause pacemaker interference or pacemaker failure.

 The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible
conditions and situations that may occur. It must be understood by the operator that common sense and caution
are factors which cannot be built into this product, but must be supplied by the operator.
 There are no user serviceable parts. Have the tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the equipment is maintained.
 Please use the included battery and charger. Risk of explosion if the battery is replaced with an incorrect type.
 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.
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.

X-431 PRO5 is a powerful Android-based diagnostic tool, which has several production configurations ranging from
commercial vehicle to passenger vehicle. It inherits from LAUNCH’s advanced diagnosing technology and is
characterized by covering a wide range of vehicles, featuring powerful functions, and providing precise test result.
Through the simple Bluetooth or USB communication between the SmartLink C device and the display tablet, it
achieves full car model and full system vehicle trouble diagnosis, which include Reading DTCs, Clearing DTCs,
Reading Data Stream, Actuation Test and Special Functions. Moreover, taking advantage of the mobile Internet, it
also integrates SmartLink (Diagnostic System), Remote Diagnose and Repair Data, which helps to diagnose
vehicle issues more efficiently, and greatly increase customer’s retention and boost shop revenue.
1.2 Features
 Intelligent Diagnose: This module allows you to use the VIN information of the currently identified vehicle to

In this ecology system, if a technician or car owner (SmartLink C) does not have time to puzzle through a touch
vehicle problem, he can seek a trusted second opinion or additional expertise on various vehicle issues from
remote master technicians or repair shops (SmartLink B). SmartLink B enables the shop owner to greatly
increase customer’s retention and boost shop revenue by providing the professional technical assistance
service.
 Remote Diagnose: This helps repair shops or mechanics to diagnose a remote vehicle, and launch instant
messages, allowing for improved efficiency and faster repairs.
 Reset: All kinds of common maintenance and reset items including Oil lamp reset, ABS bleeding, Steering angle
calibration, Tire pressure monitor system reset, Gear learning, Injector coding and DPF regeneration etc. can be
done.
 One-click Update: Lets you update your diagnostic software online.
 Diagnostic History: This function provides a quick access to the tested vehicles and users can choose to view
the test report or resume from the last operation, without the necessity of starting from scratch.
 Feedback: Enables you to submit the vehicle issue to us for analysis and troubleshooting.
 Vehicle Coverage: Quick dial to view the vehicle models that the tool covers.
 ADAS calibration: Optional. This function needs to be activated before normal use and only works with the
LAUNCH-specific ADAS calibration tool.
1.3 Components & Controls

1.3.2 SmartLink C Device
The SmartLink C device features powerful functions and it can be applied in the following situations:
1). When as a VCI (Vehicle Communication Interface), it needs to work in conjunction with the Diagnose module
of the tablet, which is used to obtain vehicle data, and then send it to the tablet for analysis via Bluetooth / data
cable.
2). When as a SmartLink C (Customer) dongle, it does not communicate with the tablet, but it needs to work
together with the SmartLink module of the tablet. The tablet is mainly used to issue remote diagnostic requests,
and the SmartLink C dongle is networked to receive and execute commands from the remote SmartLink B
(Business).
*Note: For detailed operations, please refer to Chapter 7.
3). When as a local or remote J2534 PassThru device, it can be used in conjunction with the PC installed with
OEM diagnostic software.
*Note: For detailed operations, please refer to Chapter 12.
