Important Safety Precautions
To avoid personal injury, property damage, or accidental damage to the product, read
all of the information in this section before using the tool.
DANGER
• When an engine is operating, keep the service area well-ventilated or attach a
building exhaust removal system to the engine exhaust system. Engines produce
various poisonous compounds (hydrocarbon, carbon monoxide, nitrogen oxides,
etc.) that cause slower reaction time and result in death or serious personal injury.
• Please use the included battery and power adaptor. Risk of explosion if the battery
is replaced with an incorrect type.
• DO NOT attempt to operate the tool while driving the vehicle. Have second
personal operate the tool. Any distraction may cause an accident.
WARNING
Always perform automotive testing in a safe environment.
Do not connect or disconnect any test equipment while the engine is running.
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.
NEVER smoke or allow a spark or flame in vicinity of battery or engine. Do not

operate the tool in explosive atmospheres, such as in the presence of flammable
liquids, gases, or heavy dust.
Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
Wear an ANSI-approved eye shield when testing or repairing vehicles.
Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
Use extreme caution when working around the ignition coil, distributor cap, ignition
wires and spark plugs. These components create hazardous voltage when the
engine is running.
To avoid damaging the tool or generating false data, please make sure the
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.
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 when necessary.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot
engine parts.
Store the tool and accessories in a locked area out of the reach of children.
Do not use the tool while standing in water.
Do not expose the tool or power adapter to rain or wet conditions. Water entering
the tool or power adaptor increases the risk of electric shock.
This tool is a sealed unit. There are no end-user serviceable parts inside. All
internal repairs must be done by an authorized repair facility or qualified technician.
If there is any inquiry, please contact the dealer.
Keep the tool far away from magnetic devices because its radiations can damage
the screen and erase the data stored on the tool.
Do not attempt to replace the internal rechargeable lithium battery. Contact the
dealer for factory replacement.
Do not disconnect battery or any wiring cables in the vehicle when the
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.

The throttle is in the closed position.
Find DLC location.
The DLC (Data Link Connector) is usually located 12 inches from the center of the
instrument panel, under or around the driver’s side for most vehicles. For some
vehicles with special designs, the DLC location may vary.
If the DLC cannot be found, refer to the vehicle’s service manual for the location.
3.2 Vehicle Connection
Follow the steps mentioned below to connect OBD II vehicle:
Connect one end of the included diagnostic cable to the DB15 diagnostic
connector, and the other end to the vehicle’s DLC port.
For non-OBDII vehicle, proceed as follows:
1. Select the corresponding adaptor cable according to the vehicle’s DLC type.
2. Plug the non-16pin end of the adaptor cable into the vehicle’s DLC port, then
connect the other end to the OBD I adaptor, and then tighten the captive
screws.
3. Connect the other end of the OBD I adaptor to the diagnostic cable.
Note: If the pin of the DLC is damaged or the DLC has insufficient power, you can

4 Battery
4.1 Battery Test
Battery test is specifically designed to help car owners, repair workshops,
battery factory determine whether the battery is normal or not. It supports
various battery standards and specifications, including CCA, DIN, IEC, EN, JIS,
SAE and GB etc.
Two test modes (Out-of-car Inspection & In-car Inspection) are available and
applicable to battery test.
There are mainly 5 battery states as follows:
1. Good battery - Indicates that the battery is normal.
2. Replace battery - Indicates that the battery is aged or becomes rejected, or
battery life cycle is nearly exhausted. In this case, battery voltage appears to
be normal, but the battery itself is not well, i.e. battery polarity board has been
completely vulcanized or aged. Please replace battery immediately.
3. Good-recharge - Stands for low battery. The battery is good itself.
4. Charge-retest - It is better for a few batteries to be fully charged before
testing in order to avoid judging in error under special conditions.
5. Bad cell - Indicates one of the battery cells is bad and cannot work normally,
but for which one is bad, it can’t be verified. In this case, battery voltage is
generally lower than 11V, mainly resulting from internal circuitry damage,
such as short circuit, open circuit, dummy weld etc.
4.1.1 Out-of-car Inspection
Out-of-car inspection indicates that the battery is disconnected from all loading
devices on vehicles. Only battery test is supported for this inspection.
1. Plug one end of the battery cable clamps into the circular connector of the
tool. Clamp the BLACK and RED clips of the battery cable clamps on the
Negative (-) and Positive (+) terminals of the vehicle battery
respectively.
Note: The cable connector is keyed and will only fit one way. If you have problems

connecting the cable connector to the circular connector, rotate it 180°and try again.
2. Tap Battery -> Out-of-car inspection on the tool, the following screen will
appear:
3. Tap to scan the barcode on the battery or manually input the code
printed on the battery if necessary. Or tap Next Step to enter the next step.
4. Do appearance check of the battery or directly tap Next Step to ignore it.
5. Select the correct battery type, standard and capacity according to the
battery name plate and tap Start the Detection.
6. After the detection is complete, the test result and battery state will appear on
the screen.
Tap Save Report to save the battery test report. The report can be accessed
from Reports -> Battery.
