Wear an ANSI-approved eye shield when testing or repairing vehicles.
The vehicle shall be tested in a well-ventilated work area, as engines produce various
poisonous compounds (hydrocarbon, carbon monoxide, nitrogen oxides, etc.)
Do not connect or disconnect any test equipment while the ignition is on or the engine is
running.
Put blocks in front of the drive wheels and never leave the vehicle unattended while
testing.
Do not drive the vehicle and operate the test equipment at the same time. Any distraction
may cause an accident.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine
parts.
Keep a fire extinguisher suitable for chemical, gasoline and electrical fires nearby.
Before starting the engine, put the gear lever in NEUTRAL (for manual transmission) or
PARK (for automatic transmission) to avoid injury.
To avoid damaging the test equipment or generating false data, please make sure the
vehicle battery is fully charged and the connection to the vehicle DLC (Data Link
Connector) is clear and secure.
Automotive batteries contain sulfuric acid that is harmful to skin. In operation, direct
contact with the automotive batteries should be avoided. Keep the ignition sources away
from the battery at all times.

X-431 Throttle Handset VCI (Vehicle Communication Interface)
The handset acts as the central processing system, which is used to receive and analyze the
live vehicle data from the VCI connector and then output the test result.
The VCI connector works as a vehicle communication interface device, which is used to
connect to the vehicle's DLC (Data Link Connector) socket directly or via OBD II extension
cable to read the vehicle data and then send it to the handset via wireless (BT)
communication. It only works with the vehicle with 12V battery voltage.
1. Locate vehicle’s DLC socket: The DLC (Data Link
Connector) is typically a 16-pin connector where
diagnostic code readers interface with the vehicle's
on-board computer.
It is usually located on driver’s
side, about 12 inches away from the center of
dashboard. See Figure DLC Location.
In case no DLC is found, please refer to Automobile
Repair Manual.
2.
Plug the VCI connector into the vehicle's DLC (It is suggested to use the OBD II extension
cable to connect the DLC and the VCI). Normally the power indicator of the VCI will light
up.
