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 the ECU and the sensors when the operation is next to •
them.
Ground yourself when you disassemble PROM, otherwise ECU and sensors •
will be damaged by static electricity.
Do not use the pointer ohmmeter instead of DMM to test the ECU and the •
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 rmly, otherwise electro elements, such •
as IC inside ECU, will be damaged.

The appliance is a sophisticated electronic device, never have it clashed •
when in use.
Make sure the appliance is properly connected to the DLC to avoid •
communication interruptions. During operation, keep the screen upward and
leveled.
Don’t disconnect the wired network or Wi-Fi network while software updating •
or sending E-mail, otherwise, it will be interrupted.
After the operation, the stylus shall be inserted into the hole on the back of •
the main unit, and put away the cable and connector, etc accessories to the
box to avoid the lost.

Safety Precautions
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 the ignition
sources away from the battery at all times.
Engines produce various poisonous •
compounds (hydrocarbon, carbon
monoxide, nitrogen oxides, etc,) which
should be avoided. The vehicles shall be
tested in a well-ventilated area.
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 use 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.

X-431 PAD is equipped with a built-in mini printer, which enables you to easily
print the real time test results, such as ECU No., DTCs, datastream, version
information, etc. while testing vehicle.
Loading thermal paper
This mini printer applies thermal paper roll with size of Φ30×57mm. Follow the
steps described as below to load it.
Fig. 2-2a Fig. 2-2b Fig. 2-2c Fig. 2-2d
Fig. 2-2 Installing paper
Push the printer cover located on the rear of X-431 PAD out and open it as 1.
indicated on Fig. 2-2a.
Place the unpacked thermal paper into the compartment with its starting end 2.
approaching to the paper outlet (refer to Fig. 2-2b). Reversing paper direction
will cause that no results will be printed out.
Pull out some printing paper and introduce it along the slot until it comes out 3.
of the paper outlet shown as Fig. 2-2c. Otherwise, paper can not be fed.
Close the paper cover and press it down until you hear a click. See Fig. 2-2d.4.
Notes:
1. If the printer keeps printing for a long time,
the thermal matrixes (shown as right gure)
will overheat. To avoid a risk of burning
injury, please do NOT touch the matrixes.
2. The printer applies the thermal paper, which
should be prevented from being heated
before printing, otherwise, the paper would
be no longer effective or printing results
disappear.

10 Borescope
Automotive borescope is mainly applied to those unseen parts of engine, fuel
tank, braking system. While testing a vehicle system, engine is one of the main
parts to be checked. To check if the internal of a engine is qualified or not or
whether internal carbon deposit and damage exists in the engine or not, we can
make full use of a borescope to solve these quesitons.
X-431 PAD has an optional function of borescope, which enables you to observe
the parts that can not be seen or reached with the aid of borescope. In addition,
the captured pictures and videos also provide you intuitive data for easy
analysis.
1. Connections
Connect one end of the borescope (optional) to the borescope port of X-431
PAD, and extend the other end to some unseen or unreachable parts of engine,
hydraulic system, nozzles etc. for illumination.
2. How to use
After connections are properly made, press on the X-431 PAD to turn it on.
Wait until the system enters the main menu, click [Borescope] to activate it, then
the screen will display the scene captured from the borescope lens. Adjust it until
the lens stops in the desired place, then click or button on the screen to
take a photo or record video.
For detailed operations, please refer to user’s manual included with the
borescope.
