Safety Information
For your own safety and the safety of others, and to prevent damage to the device and
vehicles upon which it is used, it is important that the safety instructions presented
throughout this manual be read and understood by all persons operating or coming into
contact with the device.
There are various procedures, techniques, tools, and parts for servicing vehicles, as
well as in the skill of the person doing the work. Because of the vast number of test
applications and variations in the products that can be tested with this equipment, we
cannot possibly anticipate or provide advice or safety messages to cover every
circumstance. It is the automotive technician’s responsibility to be knowledgeable of the
system being tested. It is crucial to use proper service methods and test procedures. It
is essential to perform tests in an appropriate and acceptable manner that does not
endanger your safety, the safety of others in the work area, the device being used, or
the vehicle being tested.
Before using the device, always refer to and follow the safety messages and applicable
test procedures provided by the manufacturer of the vehicle or equipment being tested.
Use the device only as described in this manual. Read, understand, and follow all

condition or service procedure encountered does not jeopardize your personal safety.
DANGER
When an engine is operating, keep the service area WELL VENTILATED or attach a
building exhaust removal system to the engine exhaust system. Engines produce
ii
carbon monoxide, an odorless, poisonous gas that causes slower reaction time and
can lead to serious personal injury or loss of life.
Do Not Turn the Volume Up Too Loud When Using Headphones
Listening at high volumes that over-stimulate the ear for long periods of time may result
in loss of hearing.
SAFETY WARNINGS:
Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot
engine parts.
Operate the vehicle in a well-ventilated work area, for exhaust gases are
poisonous.
Put the transmission in PARK (for automatic transmission) or NEUTRAL (for
manual transmission) and make sure the parking brake is engaged.
Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
Be extra cautious when working around the ignition coil, distributor cap, ignition
wires and spark plugs. These components create hazardous voltages when the
engine is running.
Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires nearby.
Do not connect or disconnect any test equipment while the ignition is on or the
engine is running.
Keep the test equipment dry, clean, free from oil, water or grease. Use a mild
detergent on a clean cloth to clean the outside of the equipment as necessary.
Do not drive the vehicle and operate the test equipment at the same time. Any
distraction may cause an accident.
Refer to the service manual for the vehicle being serviced and adhere to all
diagnostic procedures and precautions. Failure to do so may result in personal
injury or damage to the test equipment.
To avoid damaging the test equipment or generating false data, make sure the

Establish Vehicle Communication
The Diagnostics operations require connecting the MaxiSys MS908S/MaxiSys MS908S
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 tablet, you need to perform the following steps:
1. Connect the VCI device to the vehicle’s DLC for both communication and power
source.
2. Connect the VCI device to the tablet via BT pairing, or USB connection.
3. When these are done, check the VCI navigation button at the bottom bar on the
screen, if a green check displays at the lower right corner, the MaxiSys
MS908S/MaxiSys MS908S Pro Diagnostic Platform is ready to start vehicle
diagnosis.
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 connection to the vehicle
battery.
OBD II Vehicle Connection
This type of connection only requires the main cable without any additional adapter.
To connect to an OBD II vehicle
1. Connect the main cable’s female adapter to the Vehicle Data Connector on the
VCI device, and tighten the captive screws.
18
2. Connect the cable’s 16-pin male adapter to the vehicle’s DLC, which is
generally located under the vehicle dash.
NOTE
The vehicle’s DLC is not always located under the dash; refer to the user manual of the
test vehicle for additional connection information.
Non-OBD II Vehicle Connection
This type of connection requires both the main cable and a required OBD I adapter for
the specific vehicle being serviced.
There are three possible conditions for Non-OBD II vehicle connection:
DLC connection supplies both communication and power.
DLC connection supplies communication and power is to be supplied via the
cigarette lighter connection.
DLC connection supplies communication and power is to be supplied via
connection to the vehicle battery.

NOTE
After the VCI device is successfully connected to the vehicle, the Power LED on the
device illuminates, and a brief beep sound will be heard.
VCI Connection
After the VCI device is properly connected to the vehicle, the Power LED on the VCI
device illuminates solid green light, and is ready to establish communication with the
tablet.
The Wireless Diagnostic Interface, which comes with the MaxiSys MS908S tool kit,
supports 2 communication methods with the tablet: BT and USB.
The J2534 ECU Programming Device, which comes with the MaxiSys MS908S Pro tool
kit, supports 2 communication methods with the tablet: BT, and USB.
Pairing Up via BT
Among all methods, BT pairing is recommended as the first choice for the
communication between the tablet and the VCI device. The working range for BT
communication is about 210 feet (70 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 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 tablet with the VCI device via BT
1. If not already done, power up the tablet.
20
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 tablet is
connected to the VCI device, and is ready to perform vehicle diagnosis.
Refer to BT Pairing on page 83 for additional information.
USB Cable Connection
The USB cable connection is a simple and quick way to establish communication
between the 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 device
illuminates solid green light, indicating the connection between the devices is
successful.
The MaxiSys diagnostic platform is now ready to perform vehicle diagnosis.
NOTE
Since the USB connection provides the most stable and fastest communication, it is
highly recommended to apply this communication method when operating ECU
programming or coding. When all the two communication methods are applied at the
same time, the MaxiSys system will use the USB communication as the default priority.
No Communication Message
A. If the tablet is not connected to the VCI device, an “Error” message displays. An
“Error” message indicates the tablet is not communicating with the VCI device, and
so cannot gain access to the vehicle control module. In this case, you need to do
the following check-ups:
Check if the VCI device is powered on.
21
In case of wireless connection, check if the network is configured correctly, or
if the right device has been paired.
If during the diagnosis process, the communication is suddenly interrupted
due to the loss of signal, check if there is any object that causes signal
interruption.
Check if the VCI device is properly positioned. It is recommended to put the
VCI device with the front side up.
Try standing closer to the VCI device to obtain more stable signals, and faster
communication speed. In case of wired connection, check the cable
connection between the tablet and the VCI device.
Check if the green LED on the VCI device is illuminated for BT or USB.
Check if the Error LED on the VCI device is on, this may indicate there is a
communication error between the devices, in this case try re-establishing the
connection again; if this does not work, there may be a hardware problem with
the device, in this case contact for technical support.
B. If the VCI device is unable to establish a communication link, a prompt message
displays with check instructions. The following conditions are the possible causes
for this massage to display:
The VCI device is unable to establish a communication link with the vehicle.
You’ve selected a system for testing that the vehicle is not equipped with.
There is a loose connection.
There is a blown vehicle fuse.
There is a wiring fault on the vehicle, or the data cable or adapter.
There is a circuit fault in the data cable or adapter.
Incorrect vehicle identification was entered.
Getting Started
Prior to first use of the Diagnostics application, the VCI device must be synchronized
