4.3 Connections

4.3.1 Preparation

Normal testing conditions

 Turn on the vehicle power supply.
 Throttle should be in a closed position.

4.3.2 DLC location

The DLC (Data 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 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.

4.3.3 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 dongle into the vehicle’s DLC s ocket (It is suggested to use the
OBD II extension cable to connect the VCI dongle and DLC).

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 the tablet, and the other end to AC outlet.

B. Internal battery pack

For non-OBDII vehicle, proceed as follows:

1. Locate vehicle’s DLC socket.

2. Select the corresponding non-16pin connector.

3. Plug the non-16pin end of the connector into the DLC socket, and the other
end to the OBD I adaptor, and then tighten the captive screws.

4. Connect the other end of the adaptor to the included VCI dongle.

5. To supply power to OBD I adaptor from:
A. Cigarette Lighter Cable (optional): Connect one end of the cigarette lighter

cable to vehicle’s cigarette lighter receptacle, and the other end to the power
jack of OBD I adaptor.

17

LAUNCH X-431 PRO TP User Manual

6.3 Steering Angle Calibration

To reset the steering angle, first find the relative zero point position for the car to
drive in straight line. Taking this position as reference, the ECU can calculate the
accurate angle for left and right steering.

After replacing the steering angle position sensor, replacing steering mechanical
parts (such as steering gearbox, steering column, end tie rod, steering knuckle),
performing four-wheel alignment, or recovering car body, you must reset the
steering angle.

line, or brake fluid is replaced, the ABS bleeding function must be performed
to bleed the ABS.

6.5 Tire Pressure Monitor System Reset

This function allows you to quickly look up the tire sensor IDs from the vehicle’s
ECU, as well as to perform TPMS replacement and sensor test.

1. After the tire pressure MIL turns on and maintenance is performed, the tire

pressure resetting function must be performed to reset tire pressure and turn
off the tire pressure MIL.

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

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
performed.

6.8 Injector Coding

Write injector actual code or rewrite code in the ECU to the injector code of the
corresponding cylinder so as to more accurately control or correct cylinder
injection quantity.

After the ECU or injector is replaced, injector code of each cylinder must be
confirmed or re-coded so that the cylinder can better identify injectors to
accurately control fuel injection.

LAUNCH X-431 PRO TP User Manual

6.9 Battery Maintenance System Reset

This function enables you to perform a resetting operation on the monitoring unit
of vehicle battery, in which the original low battery fault information will be
cleared and battery matching will be done.

Battery matching must be performed in the following cases:
a) Main battery is replaced. Battery matching must be performed to clear

original low battery information and prevent the related control module from
detecting false information. If the related control module detects false
information, it will invalidate some electric auxiliary functions, such as
automatic start & stop function, sunroof without one-key trigger function,
power window without automatic function.

b) Battery monitoring sensor. Battery matching is performed to re-match the

control module and motoring sensor to detect battery power usage more
accurately, which can avoid an error message displaying on the instrument
panel.

6.10 Diesel Particulate Filter (DPF) Regeneration

DPF regeneration is used to clear PM (Particulate Matter) from the DPF filter

8 TPMS

8.1 About TPMS

A Tire Pressure Monitoring System (TPMS) is a safety device that measures,
identifies and warns the driver when one or more tires is significantly
under-inflated or over-inflated. Majority of the TPMS adopt direct tire sensors.
The TPMS sensor is typically located as a valve-mounted stem in the tire. It
works by monitoring the temperature, air pressure, and battery state in a vehicle
tire and automatically transmitting a warning to the driver via a warning light or
dashboard display. Those vehicles which have graphical displays of the TPMS
positions can then show on which wheel there is a problem.

8.2 TPMS in X-431 PRO TP

X-431 PRO TP provides the ability to activate most OEM/Universal TPMS
sensors, and allows users to reprogram sensor IDs, retrieve/clear TPMS DTCs,
