Chapter 4 Diagnostics Operations
By establishing a data link to the electronic control systems of the vehicle being
serviced through the VCI device, the Diagnostics application allows you to retrieve
diagnostic information, view live data parameters, and perform active tests. The
Diagnostics application can access the electronic control module (ECM) for various
vehicle control systems, such as engine, transmission, antilock brake system (ABS),
airbag system (SRS) and more.
4.1 Establishing Vehicle Communication
The Diagnostics operations require connecting the MaxiSys/MaxiSys Pro
Diagnostic Platform to the test vehicle through the VCI device using the main
cable, and test adapters (for non-OBD II vehicles). To establish proper vehicle
communication to the MaxiSys display tablet, you need to perform the
following steps:
1. Connect the VCI devic e t o t h e v ehicl e’s DLC for both communication and
power source.
2. Connect the VCI device to the MaxiSys display tablet via BT pairing,
USB connection, or Ethernet connection. (Ethernet connection is only
available for the J2534 Programming Device.)
3. When these are done, check the VCI navigation button at the bottom bar
on the screen, if the button displays a green tick icon at the lower right
corner, the MaxiSys/MaxiSys Pro diagnostic platform is ready to start
vehicle diagnosis.
4.1.1 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 On-board Diagnostics Two (OBD II)
management system supplies both communication and 12-volt power
through a standardized J-1962 DLC.
A vehicle not equipped with an OBD II management system supplies
communication through a DLC connection, and in some cases supplies
12-volt power through the cigarette lighter receptacle or a connect ion to
the vehicle battery.

Among all methods, BT pairing is recommended as the first choice for the
communication between the MaxiSys display tablet and the VCI device. The
working range for BT co mmunication is about 755 feet (230 m); this means
you can perform vehicle diagnosis freely around the workshop with greater
convenience.
If you use more than one VCI device to connect to the test vehicles when
customers are many, you can perform vehicle diagnosis on various vehicles
conveniently, by pairing the MaxiSys display tablet separately to each of the
VCI devices connected to the different test vehicles, via BT, without the need
to repeat the plugging and unplugging procedure, which is unavoidable
through traditional wired connection, thus saves you more time and provides
more efficiency.
To pair up the MaxiSys display tablet with the VCI device via BT
1. If not already done, power up the MaxiSys display tablet.
2. Select the VCI Manager application from the MaxiSys Job Menu.
3. When the VCI Manager application is opened, the device
automatically starts scanning for available VCI devices around for
BT pairing. The found devices are listed in the Setting section on
the right side of the screen.
NOTE: If no VCI device is found, this may indicate that the signal strength
of the transmitter is too weak to be detected. In this case try to get closer
to the device, or reposition the VCI device, and remove all possible
objects that causes signal interference. When these are done, tap the
Scan button at the top right corner to start searching again.
4. Depending on the VCI type you use, the device name may display
as Maxi suffixed with a serial number. Select the required device for
pairing.
5. When paring is successfully done, the connection status displayed
to the right of the device name is shown as Paired.
6. Wait for a few seconds, and the VCI button on the system
Navigation bar at the bottom of the screen shall display a green tick
icon, indicating the display tablet is connected to the VCI device,
and is ready to perform vehicle diagnosis.
Refer to 10.1 BT Pairing on pa ge 91 for additional information.

Diagnostics Operations Establishing Vehicle Communication
USB Cable Connection
The USB cable connection is a simple and quick way to establish
communication between the MaxiSys display tablet and the VCI device. After
properly connecting the USB cable from the tablet to the VCI device, the VCI
navigation button at the bottom bar of the screen shows a green tick icon in a
few seconds, and the USB LED on the VCI d evice i llumi nates so lid green light,
indicating the connection between the devices is successful.
The MaxiSys/MaxiSys Pro diagnostic platform is now ready to perform vehicle
diagnosis.
NOTE: Since the USB connection provides the most stable and fastest
communication, it is h igh ly rec omm ende d to apply this communic atio n method
when operating ECU programming or coding. When all the three
communication methods are applied at the same time, the MaxiSys system
will use the USB communication as the default priority.
Wired Connection v i a Et hernet
NOTE: This communication method is only available for connecting the
MaxiSys display tablet to the J2534 ECU programming device, which comes
with the MaxiSys Pro tool kit.
This section describes the general procedure to connect the tablet with the
J2534 ECU programming device via Ethernet connection. To establish
successful communication, you need to set up the network configuration on
the display tablet.
To connect the MaxiSys display tablet with the VCI device via
Ethernet
1. If not already done, power up the MaxiSys display tablet.
