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

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

1

carbon monoxide, an odorless, poisonous gas that causes slower reaction time and
can lead to serious personal injury or loss of life.

It is not advised to use headphones at a high volume

Listening at high volumes 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

4.1.1.1 Vehicle Connection

The method used to connect the VCI device to a vehicle DLC depends on the vehicle
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.

23

 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.

2. Connect the 16-pin male adapter to the vehicle DLC under the vehicle dash.

NOTE

The vehicle 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.

 To connect to a Non-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.

2. Locate the required OBD I adapter and connect its 9-pin jack to the main

cable’s male adapter.

3. Connect the attached OBD I adapter to the vehicle DLC.

NOTE

Some vehicles may have more than one adapter or may have test leads instead of an
adapter. Make the proper connection to the vehicle DLC as required.

 To connect the cigarette lighter

1. Plug the DC power connector of the cigarette lighter into the DC power supply

input port on the device.

2. Connect the male connector of the cigarette lighter into the vehicle cigarette

lighter receptacle.

 To connect the clipper cable

1. Connect the tubular plug of the clipper cable to the male connector of the

cigarette lighter.

2. Plug the DC power connector of the cigarette lighter into the DC power supply

input port of the VCI device.

24

3. Connect the clipper cable to the vehicle battery.

NOTE

After the VCI device is successfully connected to the vehicle, the Power LED on the
device lights, and a beep sound will be heard.

4.1.1.2 VCI Connection

After the VCI device is properly connected to the vehicle, the Power LED on the VCI
device lights solid green, and is ready to establish communication with the tablet.

Coming with the MaxiSys MS909 tool kit, the VCI device supports three
communication methods with the tablet: BT, Wi-Fi and USB.

Pairing Up via BT

The working range for BT communication is about 328 feet (100 m), giving technicians

greater mobility to perform vehicle diagnosis from anywhere in the repair shop.

To expedite multi-vehicle diagnostics, more than one VCI can be used in busy repair shops

enabling technicians to quickly pair via BT their MaxiSys tablet to each VCI separately and

therefore eliminating the need to unplug the VCI from one vehicle and then connect it to

another each time a new vehicle comes in for repairs.

 To pair up the tablet with the VCI device via BT

1. Power up the tablet.

2. Select the VCI Manager application from the MaxiSys Main Screen.

3. The device automatically scans 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 is too weak to be
detected. Reposition the VCI device, and remove all possible objects that may cause
signal interference. Tap the Scan button at the top right corner to rescan for VCI.

4. Typically, the VCI device name displays as Maxi suffixed with a serial number.

25

Select the VCI device for pairing. (If using more than one VCI is used in the
shop, ensure the correct VCI is selected to pair.)

5. When pairing is successful, the connection status displays as Connected.

6. The VCI icon in the bottom navigation bar displays a green circle BT icon

when the tablet and the VCI are connected.

Refer to 12.2 BT Pairing on page 120 for additional information.

Wi-Fi Connection

The VCI device supports both 2.4GHz and 5GHz Wi-Fi connection. Please choose

2.4GHz or 5GHz Wi-Fi connection according to specific situations. In open areas, the

working range of 2.4G Wi-Fi communication is up to 328 feet (100 m) while 5G Wi-Fi is
up to 164 feet (50 m).

 To pair the tablet with the VCI device via Wi-Fi

1. Power up the tablet.

2. Select the VCI Manager application from the MaxiSys Main Screen.

3. When the VCI Manager application is opened, the tablet automatically scans

for available VCI devices around for Wi-Fi connection. Found VCI devices
are listed in the Setting section on the right side of the screen.

4. Typically, the VCI device name displays as Maxi suffixed with a serial number.

Select the required device for connection.

5. When pairing is successful, the connection status is shown as Connected.

6. The VCI icon in the bottom navigation bar displays a green circle Wi-Fi icon

when the tablet and the VCI are connected.

Refer to Wi-Fi Connection on page 120 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 in the bottom bar of the screen
displays a green check mark and the USB LED on the VCI device lights solid green,
indicating the connection between the devices is successful.

The MaxiSys diagnostic platform is now ready to perform vehicle diagnosis.

NOTE

The USB connection provides the most stable and fastest communication and is
therefore the recommended communication mode between the tablet and VCI when
operating ECU programming or coding. The USB communication method will take
priority over other connected communication modes.

4.1.1.3 No Communication Message

A. If the tablet is unable to connect to the VCI, an “Error” message displays. The

“Error” message indicates the tablet is not communicating with the VCI device.
Troubleshoot the error by performing the following steps:

 Ensure the VCI device is powered on.

 When using the wireless connection, ensure the network is configured

correctly and the proper device has been connected.

 If the tablet loses communication abruptly during diagnostics, ensure

no objects cause signal interruption.

 Ensure the VCI device is properly positioned with the VCI front side up.

 Move the tablet closer to the VCI device. If using the wired connection,

ensure the cable is securely attached to the VCI.

 Ensure the VCI communication mode is lit for the selected

communication type, BT, Wi-Fi or USB.

B. If the VCI device is unable to establish a communication link, a message will

display troubleshooting instructions. Possible causes for the communication error
include:

 The VCI device is unable to establish a communication link with the

vehicle.

 A vehicle system has been selected for diagnosis that is not supported

by the vehicle.

 There is a loose connection.
