diagnostic box with the main test line.
（2）Turn on the car ignition switch and press the A80 BT key to
diagnose the vehicle (see diagram below).

①A80 BT Mainframe
②VCI box (can be directly connected to the vehicle diagnostic
seat or select ③⑤ Accessory after connecting the vehicle diagnostic
seat)
③Adapter cable (optional for non-standard OBD II 16pin
connectors)
④Measured vehicle
⑤Adapter (optional for non-standard OBD II 16pin connectors)
3.2 Precautions Before Use
（1）Battery voltage range on the car: +9~+36VDC.
（2）When the test harness is unplugged, the application hand pinch the
head of the front end of the wire harness to unplug, do not pull the middle
segment of the wiring bundle, and the plug connection beam sees the
direction of the corresponding interface flat plug, and does not tend to be
inserted to avoid damaging the terminal.
（3）When carrying out some special functions tests, users are required to
operate the device according to operating instructions. For some tests the
vehicle has to meet certain requirements, for example: engine temperature
80℃/105℃, turn off loads (such as headlights, air-conditioner, etc.), put
accelerator pedal in released position, etc.

（4）As the domestic models equipped with the electronic control system
is messy, such as the failure to test or test data is not correct, consider the
selected menu and the measured electronic control system is appropriate,
you can find the vehicle ECU, through the ECU sticker model for menu
selection.
（5）You may not have a software upgrade or consult with the company's
technical services when you do not find the vehicle or electronic control
system in the A80 BT test menu.
（6）It is forbidden to use the wiring harness of the non-Xtool technology
company to test the connection to avoid unnecessary loss.
（7）In A80 BT and vehicle communication, the direct shutdown is
prohibited. You should cancel the task before returning to the main
interface for shutdown.
（8）The use of A80 BT should be lightly handled, as far as possible to
avoid vibration or impact. To ensure the service life of the touchscreen,
touch the screen gently.
（9） During long period of non-use, please disconnect the power and
then turn off the A80 BT unit.
4. Diagnosis

4.1 Menu selection：
（1）After the VCI box is connected to the car and the A80 BT
host is successfully paired with the wireless Bluetooth, the diagnostic
interface can be performed as shown in the following figure
（2）The menu can be selected according to your needs: Choose
European car to enter the European car system, choose Asian Car Show
Asian menu, choose the American Car into the American menu, choose
the domestic car into the domestic menu, according to the model of the
diagnosis of the choice of car system to enter the search. You can
quickly search by clicking on the magnifying glass icon in the top right
corner and entering models.

（3）In addition to common system troubleshooting, the
development team also develops a range of special diagnostic functions
for some vehicles, as follows.
4.2 Test function：
（1）Using "BMW car" as an example, select "Royal Car V8.70",
and then select the "GX9" menu to enter, you can see the "Engine
system" icon, find the UMC engine system (UDS), click into the
following image:

The main function menu for different cars is slightly different, and the
following options are included in the common main features menu:
Read version information: This function reads the ECU version
information and displays it as “system identification” or “system
information” menu in some electronic control. It has the same meaning,
and reads the software and hardware versions related to the ECU, the
model of the diesel engine, Information such as the date of manufacture
and part number. It is convenient for us to make records during the
maintenance process, and also facilitate future data feedback and data
management.

Read ECU: read the current fault code in the ECU.
Read DTCs: Read the fault codes of the history store in the ECU.
Clear DTCs: Clear the current and historical fault code memory
stored in the ECU. It can be cleared only after all faults have been
eliminated. If there is a fault that is not eliminated, the fault code cannot
be successfully cleared. The fault code is always stored in the ECU and
read this fault code ever. Recommendation: Do not remove the fault code
casually. After reading the fault code, we must first record the fault
content for the maintenance reference. When the fault is processed, there
will be no fault code after re-reading the fault code.
Read live data: It is to read the parameters of the current engine
running, such as oil pressure, temperature, engine speed, fuel temperature,
coolant temperature, intake air temperature and so on. Through these
parameters, we can basically directly determine which problems have
occurred, so that we have narrowed the scope when performing
maintenance, which is more convenient. For many vehicles in the actual
operation process, because of the deviation of the operating
characteristics of the electronic components, the sensitivity reduction,
which all can be judged in the data stream; For this function, we need to
be very familiar with the parameters of the engine, such as: idle speed
For 800RPM or 750RPM, when the operating temperature of the coolant
