4.5 Connections
4.5.1 Preparation
Normal testing conditions
Turn on the vehicle power supply.
Vehicle battery voltage range should be 9-18V.
Throttle should be closed at its close position.
4.5.2 DLC location
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a
standard 16-pin connector where 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 DLC is not located under dashboard, a label should be there telling
location. For some Asian and European vehicles, the DLC is located behind the
LAUNCH X-431 V V4.0 User Manual
17
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.
4.5.3 Vehicle connection
The method used to connect the VCI device 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 device into the vehicle’s DLC socket (It is suggested to use the
OBD II extension cable to connect the VCI device and DLC socket).
3. Choose one of the two ways to obtain power from:
A. Power adaptor: Connect one end of the included power adaptor to
charging port of the tablet, and the other end to AC outlet.
B. Internal battery pack
For non-OBDII vehicle, proceed as follows:

4.7 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that are stored by the on-board
computer diagnostic system in response to a problem found in the vehicle.
LAUNCH X-431 V V4.0 User Manual
19
These codes identify a particular problem area and are intended to provide you
with a guide as to where a fault might be occurring within a vehicle. DO NOT
replace parts based only on DTCs without first consulting the vehicle’s service
manual for proper testing procedures for that particular system, circuit or
component.
OBD II Diagnostic Trouble Codes consist of a five-digit alphanumeric code.
• The 1st character is a letter (B, C, P or U). It identifies the “main system”
where the fault occurred (Body, Chassis, Powertrain, or Network).
• The 2nd character is a numeric digit (0 thru 3). It identifies the “type” of code
(Generic or Manufacturer-Specific).
Notes:
• Generic DTCs are codes that are used by all vehicle manufacturers. The standards
for generic DTCs, as well as their definitions, are set by the Society of
Automotive Engineers (SAE).
• Manufacturer-Specific DTCs are codes that are controlled by the vehicle
manufacturers. The Federal Government does not require vehicle manufacturers
to go beyond the standardized generic DTCs in order to comply with the new
OBD II emissions standards. However, manufacturers are free to expand beyond
the standardized codes to make their systems easier to diagnose.
• The 3rd character is a letter or a numeric digit (0 thru 9, A thru F). It identifies
the specific system or sub-system where the problem is located.
• The 4th and 5th characters are letters or numeric digits (0 thru 9, A thru F).
They identify the section of the system that is malfunctioning.

5 Diagnosis
5.1 Intelligent Diagnosis
Through simple Bluetooth communication between the display tablet and VCI,
you can easily get the VIN (Vehicle Identification Number) information of the
currently identified vehicle. Once the VIN is successfully identified, the system
will retrieve it from the remote server and then guide you to vehicle information
page without the necessity of step-by-step manual menu selection.
The vehicle information page lists all historical diagnostic records of the vehicle,
which lets the technician have a total command of the vehicle faults. In addition,
a quick dial to local diagnosis and diagnostic function are also available on this
page for reducing the roundabout time and increasing productivity.
Notes:
• Before using this function, please make sure the VCI is properly connected to the

2. Tire pressure resetting must be performed after maintenance is performed in
the following cases: tire pressure is too low, tire leaks, tire pressure
monitoring device is replaced or installed, tire is replaced, tire pressure sensor
is damaged, and tire is replaced for the car with tire pressure monitoring
function.
6.6 Gear Learning
The crankshaft position sensor learns crankshaft tooth machining tolerance and
saves to the computer to more accurately diagnose engine misfires. If tooth
learning is not performed for a car equipped with Delphi engine, the MIL turns on
after the engine is started. The diagnostic device detects the DTC P1336 'tooth
not learned'. In this case, you must use the diagnostic device to perform tooth

learning for the car. After tooth learning is successful, the MIL turns off.
After the engine ECU, crankshaft position sensor, or crankshaft flywheel is
replaced, or the DTC 'tooth not learned' is present, tooth learning must be
performed.
6.7 IMMO Service
An immobilizer is an anti-theft mechanism that prevents a vehicle’s engine from
starting unless the correct ignition key or other device is present. Most new
vehicles have an immobilizer as standard equipment. An important advantage of
this system is that it doesn’t require the car owner to activate it since it operates
automatically. An immobilizer is considered as providing much more effective
anti-theft protection than an audible alarm alone.
As an anti-theft device, an immobilizer disables one of the systems needed to
start a car’s engine, usually the ignition or the fuel supply. This is accomplished
by radio frequency identification between a transponder in the ignition key and a
device called a radio frequency reader in the steering column. When the key is
placed in the ignition, the transponder sends a signal with a unique identification
code to the reader, which relays it to a receiver in the vehicle’s computer control
module. If the code is correct, the computer allows the fuel supply and ignition
systems to operate and start the car. If the code is incorrect or absent, the
computer disables the system, and the car will be unable to start until the correct
key is placed in the ignition.
To prevent the car being used by unauthorized keys, the anti-theft key matching
function must be performed so that the immobilizer control system on the car
identifies and authorizes remote control keys to normally use the car.
When the ignition switch key, ignition switch, combined instrument panel, ECU,
BCM, or remote control battery is replaced, anti-theft key matching must be
