Diagnostics Operations
By establishing a data link to the electronic control systems of the vehicle
being serviced directly, 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.

The Diagnostics operations require connecting the MaxiCheck MX808
diagnostic platform to the test vehicle using the main cable.

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.
