Precautions on Using X-431 EURO TAB

Before using this test equipment, please read the following safety information
carefully.

 Always perform automotive testing in a safe environment.

 If the diagnostic connector remains unused 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 test equipment 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 test equipment 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

manual transmission) or in the Park (for automatic transmission) position to
avoid injury.

 To avoid damaging the test equipment 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.

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

connector: wireless Bluetooth and USB cable. You may choose any one of the
methods to diagnose a vehicle.

Fig. 4-7

Notes:

 While using the diagnosis via Bluetooth, the VCI connector should be paired with

the X-431 EURO TAB tablet. If no Bluetooth setting is done before diagnostic
software is launched, you can also configure it while using the software.

 To obtain stable communication, you are strongly recommended to perform the

vehicle diagnosis via USB cable. In this case, the USB cable is required to connect
the VCI connector and the X-431 EURO TAB tablet.

4.4 Connections

4.4.1 Preparation

Normal testing conditions

 Turn on the vehicle power supply.
 Vehicle battery voltage range should be 9-14Volts.
 Throttle should be in a closed position.

4.4.2 DLC location

17

LAUNCH X431 EURO TAB User Manual

(C) Diagtools & Launch Europe www.diagtools.lv, Riga, Pernavas 43A, LV-1009, t. [phone], [phone]

diagnostic code readers interface with the vehicle’s on-board computer. The
DLC is usually located 12 inches from the center of the instrument panel (dash),
under or around the driver’s side for most vehicles. If Data Link Connector is not
located under dashboard, a label should be there telling location. For some
Asian and European vehicles, the DLC is located behind the ashtray and the
ashtray must be removed to access the connector. If the DLC cannot be found,
refer to the vehicle’s service manual for the location.

Fig. 4-8

4.4.3 Vehicle connection

The method used to connect the diagnostic connector to a vehicle’s DLC
depends on the vehicle’s configuration as follows:

 A vehicle equipped with an OBD II management system supplies both

communication and 12V power through a standardized DLC.

 A vehicle not equipped with an OBD II management system supplies

communication through a DLC connection, and in some cases supplies 12V
power through the cigarette lighter receptacle or a connection to the vehicle
battery.

Follow the steps mentioned below to connect OBD II vehicle:

1. Locate vehicle’s DLC socket.

2. Plug the VCI connector into the vehicle’s DLC socket (It is suggested to use
the OBD II extension cable to connect the VCI connector and DLC socket.).

Fig. 4-9

3. Choose one of the two ways to obtain power from:
A. Power adaptor: Connect one end of the included power adaptor to DC IN

port of X-431 EURO TAB tablet, and the other end to AC outlet.

B. Internal battery pack

For non-OBDII vehicle, proceed as follows:

5 Diagnosis & Reset

5.1 Start Diagnostics

Tap “Diagnose” to enter the vehicle selection page.
2 approaches are provided for you to access the vehicle diagnostic software.

Choose any one of the following ways:

1. VINSCAN enables you to access it more quickly.

In this case, automatic scan (OBD VIN) and manual input (INPUT VIN) are
available.

OBD VIN: In this mode, the VCI connector should be plugged into the vehicle’s
DLC first, and then a Bluetooth communication should be established between
X-431 EURO TAB and the vehicle.

Tap “OBD VIN” to start VIN scanning on the vehicle ECU. Once the test vehicle
is successfully identified, X-431 EURO TAB will guide you to the diagnostic
software of the vehicle directly.

Note: Before using this function, the corresponding diagnostic software and Auto

search file need to be downloaded on your tool first while downloading the diagnostic
software.

INPUT VIN: In this mode, you need to input the VIN manually. In general, vehicle
identification numbers are standardized - all contain 17 characters. VIN
characters may be capital letters A through Z and numbers 1 through 0; however,
the letters I, O and Q are never used in order to avoid mistakes of misreading.
No signs or spaces are allowed in the VIN.

The most recognizable location for this number is in the top left corner on the
vehicle’s dashboard. Other locations include the driver’s door or post, and the
firewall under the hood.

Tap “INPUT VIN” and a screen similar to Fig. 5-2 will appear:
