Diagnostics
The Diagnostics application can access the electronic control module of multiple vehicle
control systems, including but not limited to the engine, transmission, anti-lock brake
system (ABS), and airbag system (SRS).
4.1 Establish Vehicle Communication and Selection
4.1.1 Establish Vehicle Communication
The Diagnostics operations require connecting the MaxiCOM tablet to the test vehicle
through the VCI using the Main Cable V2.0 (Use the applicable OBDI-type adapter if
needed). To establish proper vehicle communication with the tablet, you need to perform
the following steps:
1. Connect the VCI to the vehicle's DLC for both communication and power source.
2. Connect the VCI to the tablet via Bluetooth pairing, Wi-Fi or USB connection.
3. When the above steps are completed, check the VCI navigation button at the bottom
bar on the screen. If a green BT, Wi-Fi or USB icon appears at the lower-right corner,
the MaxiCOM Diagnostics Platform is ready to start vehicle diagnosis.
4.1.1.1 Vehicle Connection
The method used to connect the VCI to a vehicle's DLC depends on the vehicle's
configuration as follows:
A vehicle equipped with an On-board Diagnostics Two (OBDII) management system
supplies both communication and 12-volt power through a standardized J-1962 DLC.
A vehicle not equipped with an OBDII management system supplies communication
through a DLC connection, and in some cases supplies 12-volt power through the
auxiliary power outlet or a connection to the vehicle battery.
OBDII Vehicle Connection
This type of connection only requires the main cable without any additional adapter.
To connect to an OBDII vehicle
1. Connect the main cable's female adapter to the Vehicle Data Connector on the
VCI, and tighten the captive screws.
2. Connect the cable's 16-pin male adapter to the vehicle's DLC, which is generally
located under the vehicle dashboard.
