Safety Precautions
Precautions on Operating
Vehicle’s ECU
Do not disconnect the vehicle inner
consumer when the ignition switch is on.
High voltage transients may encounters at
the moment of disconnecting, and thus may
damage sensors and ECU.
Protect the computer from magnetic object
(such as wireless speaker)
Do cut off the power supply of ECU system
before welding on the vehicle.
Pay more attention to ECU and sensors
when operation is next to them.
Ground yourself when you disassemble
PROM, otherwise ECU and sensors will be
damaged by static.
Do not use the pointer ohmmeter instead of
DMM for testing ECU and sensor without
special requirement.
Do not test electric devices in relation with
ECU with a test lamp unless otherwise
expressly provided.
Do wear a metal ground strip that one end
around your wrist and the other to the
vehicle body when you get in and out the
vehicle.
Do connect ECU harness connector firmly,
otherwise electro elements, such as IC
inside ECU, will be damaged.
Precaution on Operation
The X-431IV is a sophisticated electronic
device, never have it clashed when in use.
Main unit screen may flash at the moment
engine ignition, it’s normal.
You may unplug the main unit if the
program cannot be actuated or confused
screen occurs. Plug again to continue the
operation.
Make sure that the X-431IV is properly
connected to the DIAGNOSTIC
CONNECTOR to avoid communication
interruptions.
X-431IV is equipped with a leather Strap for
easy handling when traveling or taking it
Be careful when plugging and unplugging
the main cable and diagnostic connector.

only from the tested vehicle to prevent the
ECU from being damaged
Precautions on Vehicle
Automotive batteries contain sulfuric acid
that is harmful to skin. In operation, direct
contact with the automotive batteries should
be avoided. Pay attention not to splash the
sulfuric acid into eyes. Keep ignition
sources away from the battery at all times.
Engines produce various poisonous
compounds (hydrocarbon, carbon
monoxide, azotes oxides, etc,), which
should be avoided.
Avoid contacting high temperature
assembly such as water tank and vent-pipe,
as the temperature of the running engine is
very high.
Before starting engine, put the speed lever
in the neutral position or in the P position to
avoid injury.
Wear an ANSI-approved eye shield when
testing or repairing vehicles.
If you are using the battery as a power
source, connect the RED (+) battery clip to
the positive of the vehicle battery and the
BLACK (-) battery clip to the negative.

1. Introduction
1.1 General descriptions
X-431IV is a newly developed diagnostic tool,
which uses the open operating system of X-431
series and inherits a number of advantages of
Launch’s diagnosing technology, including a wide
coverage of vehicle model, powerful test
functions and precise test data, etc.
Meanwhile, X-431IV is equipped with a rotatable
diagnostic connector, which makes it more
convenient and flexible to use.
Additionally, X-431IV is highly improved in
respect of the following:
Appearance: The X-431IV integrates
Smartbox, miniprinter and main unit as a
whole set, which eliminates the
communication failure caused by frequent
unplugging and loose connections, and also
reduces the communication time between
Smartbox and main unit.
Core CPU: utilizes the self-owned
high-speed processor chip and integrates
signal processing and relay modules.
Connector: The X-431IV has a new
SMART OBDII-16E connector to replace all
CAN Bus and OBD Connector. The
diagnostic connector can be rotated within
an angle of 90° and is flexible to use.
Performance: Software structure has been
optimized. It runs more rapidly and stably
and can directly diagnose without
downloading diagnostic programs.
on the X-431IV stands for Car Cloud logo.

platform for world-wide automobile aftermarket,
which, as one of core Telematics applications,
aims to provide data processing and application
service for car users and all Telematics service
providers of automotive aftermarket by collecting
front-end DBS diagnostic data, and combining
mobile internet and background cloud processing
technology.
1.2 Features
Diagnose: it can diagnose all electrical
control systems of vehicle (including read
DTCs, clear DTCs, read datastream etc.)
PDA: supports handwriting input, personal
database, vast vocabulary
English-Chinese dictionary.
