Precautions on Using This Tool

Before using this tool, please read the following safety information carefully.

 Always perform automotive testing in a safe environment.

 If the VCI (Vehicle Communication Interface) device is not in use for a long

period of time, it is suggested to unplug the connector from vehicle’s DLC to
conserve battery power.

 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

while testing.

 Keep the tool dry, clean, free from oil, water or grease. Use a mild detergent

on a clean cloth to clear the outside of the equipment as necessary.

 Do not drive the vehicle and operate the tool 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.

 Before starting the engine, put the gear lever in the Neutral position (for

manual transmission) or in the Park (for automatic transmission) position to
avoid injury.

 To avoid damaging the tool 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.

Precautions on Operating Vehicle’s ECU

 Do not disconnect battery or any wiring cables in the vehicle when the ignition

switch is on, as this could avoid damage to the sensors or the ECU.

 Do not place any magnetic objects near the ECU. Disconnect the power

supply to the ECU before performing any welding operations on the vehicle.

 Use extreme caution when performing any operations near the ECU or

sensors. Ground yourself when you disassemble PROM, otherwise ECU and
sensors can be damaged by static electricity.

 When reconnecting the ECU harness connector, be sure it is attached firmly,

otherwise electronic elements, such as ICs inside the ECU, can be damaged.

4.4 Connections

4.4.1 Preparation

Normal testing conditions

 Turn on the vehicle power supply.
 Throttle should be in a closed position.

4.4.2 DLC location

The DLC (Data Link Connector) is typically a standard 16 pin connector where
diagnostic code readers interface with the vehicle’s on-board computer. The
DLC is usually located 12 inches from the center of the instrument panel (dash),
under or around the driver’s side for most vehicles. If Data Link Connector is not
located under dashboard, a label should be there telling location. For some
Asian and European vehicles, the DLC is located behind the ashtray and the
ashtray must be removed to access the connector. If the DLC cannot be found,
refer to the vehicle’s service manual for the location.

Fig. 4-9

4.4.3 Vehicle connection (For Passenger Vehicle Version)

The method used to connect the diagnostic connector to a vehicle’s DLC
depends on the vehicle’s configuration as follows:

 A vehicle equipped with an OBD II management system supplies both

communication and 12V power through a standardized DLC.

 A vehicle not equipped with an OBD II management system supplies

communication through a DLC connection, and in some cases supplies 12V
power through the cigarette lighter receptacle or a connection to the vehicle
battery.
