Power On/Off
1) Power on
The device can be powered on in the following ways:
By the vehicle: plug one end of the main diagnostic test line into
the DB-15 interface of the device, and the other end into the
diagnostic interface of the vehicle, and the device will
automatically start up. If it doesn’t start up, it may be that there is
no power supply for the vehicle diagnostic seat, and the device
can be powered by the cigarette lighter or battery clamp.
By the power adapter: plug one end of the main diagnostic test
line into the DB-15 interface of the device, and connect the power
interface to the power adapter, and the device will start
automatically.
Note: the voltage of the power supply should be within the scope
of application of the product equipment. If it is beyond the scope,
the product may be damaged.
2) Power off

Before power off, please stop all diagnostic items and return back
to the main interface.
Pull out the diagnostic main test line from the diagnostic interface
of the vehicle. If the device is not equipped with battery, the
device will shut down automatically after disconnecting the main
test line from the diagnostic interface of the vehicle.
Vehicle Diagnostic Preparation
The diagnostic program establishes data connection through the
vehicle electronic control system connected with the equipment,
which can read the vehicle diagnostic information, view the data
flow, and perform action test and other functions. For details of
the functions, please refer to the model which you purchased.
To establish good communication between the diagnostic
program and the vehicle, the following operations need to be
performed:
1) Turn off the ignition;
2) Find the diagnostic interface of the vehicle: it is usually
located on the driver side; If the diagnostic interface is not found,
please refer to the vehicle maintenance manual;
3) Insert one end of the diagnostic main test line into the
device DB-15 connector and tighten the retaining screws. The
other end is connected to the vehicle's diagnostic interface.
Note: Before the equipment is connected to the vehicle, it is
necessary to judge whether the diagnostic seat of the vehicle is
a standard OBD-II interface or a non-standard OBD-II interface.
The vehicle compatible with OBD-II management system
only needs to use the integrated main test line OBD
connector to connect with the vehicle diagnosis seat and
provide power;

For vehicles that are not compatible with the OBD-II
management system, the corresponding connector should be
selected; Some vehicles need to be powered by other vehicle
power sources.
The following is an operation description of these two connection
modes.
1) Connection of standard OBD-II interface
The vehicle connected with a standard OBD-II interface only
needs to use the integrated main test line OBD connector, and
no other connectors are needed, as shown in the figure:
2) Connection of non OBD-II interface
Vehicles with a non-standard OBD-II interface need to connect
the main test line with the corresponding special connector, as
shown in the figure:

Note: at this time, the equipment is powered by the vehicle
diagnosis seat, and the equipment starts automatically. If not, it
may be that the vehicle diagnosis seat has no power supply, and
the equipment can be powered by the cigarette lighter or battery
clip.
