liquids. Fuel, oil vapors, hot steam, hot toxic exhaust gases,
acid, refrigerant and other debris produced by a malfunction
engine can cause serious injury or death. Do not use code
reader in areas where explosive vapor may collect, such as in
below-ground pits, confined areas, or areas that are less than 18
inches (45 cm) above the floor.
Do not smoke, strike a match, or cause a spark
near the vehicle while testing and keep all sparks, heated items
and open flames away from the battery and fuel / fuel vapors as
they are highly flammable.
Keep a dry chemical fire extinguisher suitable for
gasoline, chemical and electrical fires in work area.
Always be aware of rotating parts that move at high
speed when an engine is running and keep a safe distance from
these parts as well as other potentially moving objects to avoid
serious injury.
Do not touch engine components that get very hot
when an engine is running to avoid severe burns.
Block drive wheels before testing with engine
running. Put the transmission in park (for automatic transmission)
or neutral (for manual transmission). And never leave a running
engine unattended.
Do not wear jewelry or loose fitting clothing when
working on engine.
Make sure to turn off ignition before connecting or
disconnecting the code reader.

4. Introduction
VS70 is developed by the most distinguished mind of the
industry. It is specially designed to read/clear codes, read live
data, retrieve freeze data and request vehicle information on
OBDII/EOBD compliant cars, SUVs, light-duty truck and
mini-vans sold worldwide since 1996.
4.1 About OBDII/EOBD
What is OBD?
The first generation of On-Board Diagnostics or OBD I was

Erase Codes
Live Data
Freeze Data

introduced in early 1980's to control engine functions and
diagnose engine problems by vehicle manufacturers. As the
OBDI lacked standardization of protocols and interface, it
allowed different interpretations among vehicle manufacturers.
OBDII, the second generation On-Board Diagnostics, improved
in both capability and standardization, is a system developed in
mid 1990’s by the Society Automotive Engineers (SAE) to
standardize automotive electronic diagnosis. EOBD is European
version of OBDII required in Europe since 2001.
The OBDII standard specifies:
●A generic diagnostic port (Data Link Connector) and
its pinout;
●The protocols and the messaging format;
●A standard list of vehicle parameters identifications;
●A standard list of diagnostic trouble codes (DTCs);
Data Link Connector
The Data Link Connector (DLC) is a standard 16-pin interface
located under the dashboard on the driver's side of the
passenger compartment. If the DLC is not located under the
dashboard as stated, a decal describing its location should be
attached to the dashboard in the area where the DLC should
have been located.
NOTE On some Asian and European vehicles the DLC is
located behind the “ashtray”, which must be removed to
access it, or on the far left corner of the dash. If the DLC
cannot be found, consult the vehicle’s service manual for
the location.

Diagnostic Trouble Codes (DTCs)
Diagnostic Trouble Codes (DTCs) are faults stored by vehicle
computers when problems that affect engine performance and
emissions are detected. DTCs are used to help identify the
cause of a trouble or troubles with a vehicle, and determine the
fault location(s).
DTCs consist of a five-digit alphanumeric code. Please see
below for the DTCs format and code types.
