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 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 device to the vehicle’s DLC for both communication and

power source.

2. Connect the VCI device to the MaxiSys display tablet via Bluetooth

pairing or USB connection.

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 Mini 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 connection to

the vehicle battery.
