The tablet supports 2 communication methods with the VCI device: WLAN
(wireless) and wired (data cable). You may choose any one of the methods to
diagnose a vehicle.

*Notes:



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

vehicle diagnosis via data cable. In this case, the data cable is required to connect
the VCI device and the tablet.

When all communication methods are applied at the same time, the system will

use the wired communication as the default priority.

4.4 Connections

4.4.1 Preparation

Normal testing conditions

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

4.4.2 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.

Fig. 4-9

4.4.3 Vehicle connection (For Passenger Vehicle Version)

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.

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 device.

5. To supply power to OBD I adaptor from:

A. Cigarette Lighter: Connect one end of the cigarette lighter cable to vehicle’s
cigarette lighter receptacle, and the other end to the DC-IN jack of the VCI
device.

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.

6.4 ABS Bleeding

This function allows you to perform various bi-directional tests to check the
operating conditions of Anti-lock Braking System (ABS).

1. When the ABS contains air, the ABS bleeding function must be performed to
bleed the brake system to restore ABS brake sensitivity.

2. If the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake
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
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

60

X-431 EURO TAB II User Manual

(c) Launch & Diagtools. Tel. [phone]. www.diagtools.lv

Diagtools

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
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.

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
through continuous combustion oxidation mode (such as high temperature
heating combustion, fuel additive or catalyst reduce PM ignition combustion) to
stabilize the filter performance.

DPF regeneration may be performed in the following cases:
a) The exhaust back pressure sensor is replaced.
b) The PM trap is removed or replaced.
c) The fuel additive nozzle is removed or replaced.
d) The catalytic oxidizer is removed or replaced.
e) The DPF regeneration MIL is on and maintenance is performed.
f) The DPF regeneration control module is replaced.

6.11 Electronic Throttle Position Reset

*Note: Choose corresponding cables and test probes according to different terminals.

9.3.2 Simulation test

Simulation test enables users to exactly judge if the sensor is good or not to
avoid replacing components blindly. For example, the trouble code indicates the
fault is in water temperature sensor itself. But we need to confirm whether the
fault results from water temperature sensor or the connections between ECU
and sensors, or ECU itself. In this case, we can make full use of simulation test
to input the signal of simulating water temperature sensor, instead of water
temperature sensor, to the microcomputer. If the engine works better and the
fault vanishes, the fault is in the water temperature sensor. If the fault still occurs,
input the signal to the corresponding terminals of ECU. Consequently, if the fault
disappears, the fault lies in the connection between water temperature sensor
and ECU, otherwise, the fault exists in ECU.

After all connections are properly made (refer to Chapter 9.3.1 for details), turn
the tablet on and enter the Home screen, then tap “Toolbox” -> “Sensor” to enter
the test selection screen. See Fig. 9-2.

9.3.3 Precautions on checking vehicle sensor

 Hold the connector when plugging or unplugging it. Do not pull the cable for

unplugging.

 At first check the fuse, fusible line and terminals. Then check others after

eliminating these faults.

 When measuring voltage, the ignition switch should be on and the battery

voltage should not be less than 11V.

 When measuring voltage, please shake the lead lightly in the vertical and

horizontal direction for more precision.

 When checking whether there is open in the line, disconnect the CEU and the

relevant sensor at first, then measure the resistance among the ports of
sensor in order to determine whether open-circuit / contact fault exists or not.

77

(c) Launch & Diagtools. Tel. [phone]. www.diagtools.lv

Diagtools

 When checking if there is a short in the line, please disconnect the CEU and

the relevant sensor, then measure the resistance value of the ports between
the connected port and the vehicle body. If the resistance value is more than
1MΩ, no fault occurs.

 Before disassembling the engine electrical control system cable, cut off the

power supply, that is, turn the ignition switch OFF and disconnect the cables
on the battery poles.

 Contact the test probe and the two terminals/ the two leads to be measured

when measuring the voltage between the two terminals or the two leads.

 Contact the red test probe to the terminal/ the cable to be measured, and the

black probe to the ground when measuring voltage of one terminal/ one
cable.

 When checking the continuity of the terminals, contacts and leads, the

method for measuring their resistances can be used.

 Check the faults in the terminals of the CEU to sensors, relays, etc.
 There are two test probes in the testing wire. The black one is the common

signal terminal (signal GND); the red one is the input terminal for voltage,
resistance, and frequency test and output terminal for simulation voltage,
simulation frequency and oxygen sensor. Please choose the correct probes
to match the different terminals.

11.2 Test Environment

11.2.1 Test environment

Inside the vehicle test indicates that the battery connects to loading devices,
such as engine, etc. After doing battery test, it can perform charging system and
actuation system test, which is proceeded as a whole simultaneously. Charging
system and actuation system test is not required but must not be performed
before battery test. Because it is difficult for vehicle technicians to judge where is
faulty exactly if they have the faintest idea of battery’s status itself.

Outside the vehicle test indicates that the battery is disconnected from all
loading devices on vehicles. Therefore, only battery test is supported in this
condition.

11.2.2 Battery status and description

There are mainly 5 states as follows:

No.

1 Good battery Indicates battery is normal.

2 Replace battery

3 Good-recharge Stands for low battery. The battery is good itself.

4 Charge-retest

5 Bad cell

States Descriptions

Indicates that battery is aged or becomes rejected, or
battery life cycle approaches to be exhausted. In this
case, battery voltage appears to be normal, but
battery itself is not well, i.e. battery polarity board has
been completely vulcanized or aged. Please replace
battery immediately.

It is better for a few batteries to be fully charged
before testing in order to avoid judging in error under
special conditions.

Indicates one of the battery cells is bad and cannot
work normally, but for which one is bad, it can’t be
verified. In this case, battery voltage is generally lower
than 11V, mainly resulting from internal circuitry
damage, such as short circuit, open circuit, dummy
weld etc.

The following operation steps are identical to Steps 6~7 in Chapter 11.4.2
Battery test. Please refer to it for details.

11.5 Precautions On Battery Test

For the purpose of getting accurate test results, unless otherwise special
required, all loads need to be power off such as headlamp, engine etc. before
testing battery.

The operating time required for charging system and actuation system test

88

X-431 EURO TAB II User Manual

(c) Launch & Diagtools. Tel. [phone]. www.diagtools.lv

Diagtools

varies from person to person. If the engine does not start or accelerate within 30
seconds, the system will prompt you “receiving timeout” and return to the initial
status.

Whether Engine is off or not has no influence on charging and actuation test
result after increased speed is detected, but other loads need to be powered off.

The accuracy of battery voltage, charging voltage, start voltage is 0.01V in test
results; CCA (Cold Cranking Amps) precision is 5CCA.

Generally, charging voltage value is greater than starting voltage.

Charging voltage range is as follows: 13.8--14.5V for domestic vehicle;

13.3--15.5V for imported vehicles. The voltage varies with different car models,
so you have to judge based on related vehicle models. In general, the DC
voltage is stable, but it also varies with different revolution speed.

Starting voltage range: The value higher than 9.6V is regular, otherwise it is too
low. Due to different situations, whether the starting voltage is higher or not does
not mean the vehicles or batteries are faulty. For detailed faults, other special
equipments are needed. To validate the accuracy of the value, the best method
is to collect the signals of starting and charging voltage and observe it on an
oscillometer.

Generally, the voltage is lower than 11V for the bad cell battery, but it is possible
that the battery is completely exhausted or has a serious low capacity. In this
case, just recharge your battery. Bad cell always happens when the loads on a
stopping vehicle are turned on for a long time.

Please note that it is normal for quick detecting of “Increase speed” because it
follows the theory of detecting “Increase speed”: If the detected voltage is higher
than the previous battery test voltage, the system will prompt you a message of
“Engine has been speeded”

It has no influence on test result in the event that engine’s output voltage or
engine revolution is not very stable. No matter whether the vehicle is accelerated
or not, the output voltage only differs within 0.2V.

While doing inside the vehicle test, Kelvin clip is always found to be in poor
contact. To remain it in good contact, please shake it several times before
testing. Take down the battery connector, and test it again, the value probably
varies. The deviation may arise from battery connector.

Pay more attention to connect the clip. The battery poles connect with conductor,
which makes the clip has a poor connection when testing battery. A tolerance of
dozens of CCA occurs if the clip is out of position, or oil, dust attaches on the
pole. The gear and main body of clip should be fully matched with battery poles.

*Notes:

1. Battery poles inside the vehicle are enveloped by connectors, which may produce
some errors for test results. The tolerance results from the resistance of
connectors. The greater the resistance value is, the greater the tolerance becomes.
But generally, the tolerance does not affect the test conclusion.

2. Testing the battery separately generates an exact test result. The battery box is a
very useful auxiliary tool for quick test. If any problems were found, test it
separately for getting an exact test result.

12 Oscilloscope (Toolbox)

12.1 Introduction

As an optional add-on module, the Scopebox includes automotive oscilloscope
and automotive ignition waveform.

Automotive oscilloscope can make the auto repair technician quickly judge the
faults on automotive electronic equipment and wiring, and the oscilloscope
sweep speed is far greater than the signal frequency of such vehicles, usually
5-10 times of the measured signal. The automotive oscilloscope not only can
quickly acquire the circuit signal, but also can slowly display the waveform to
observe and analyze. It can also record and store the tested signal waveform
which can be recalled to observe for the fast signal, having great convenience to
failure analysis. Either high-speed signal (e.g.: Injection nozzle, intermittent fault
signal) or the slow-speed signal (e.g. the throttle position change and the oxygen
sensor signal) can be observed through automotive oscilloscope in an
appropriate waveform.

The electronic signal can be compared and judged via measuring five
parameters indexes. The five parameters are the amplitude (the maximum
voltage of signal), the frequency (the cycle time of signal), the shape (the
appearance of signal), the pulse width (the duty cycle or the time range of signal),
and the array (the repetition characteristic of signal), which can be tested,
displayed, saved by the automotive oscilloscope. Via the waveform analysis can
further detect the circuit fault on sensors, actuators, circuits, and electronic
control units, etc.
