Power On/Off
Power on
The device can be powered on in the following ways:
Vehicle power on: 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

HD Series

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.
Power on the power adapter: plug one end of the main
diagnostic test line into the DB-15 interface of the device,
connect 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.
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

HD Series
7
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 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:

HD Series
8
2) Connection of non OBD-II interface
Vehicles with non OBD-II interface need to connect the main
test line with the corresponding special connector, as shown in
the figure:

HD Series

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.
