Do not route the test cable in a manner that would interfere
with driving controls.
Do not exceed voltage limits between inputs specified in
this user’s manual.
Always wear ANSI approved goggles to protect your eyes
from propelled objects as well as hot or caustic 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

4. Introduction
VS80 is developed by the most distinguished mind of the industry. It is
specially designed to support all 9 OBDII service modes, including live
data, O2 sensor test and more, 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 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 since2001.
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
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

VS80 OBDII/EOBD Code Reader User’s Guide_English Version_V1.10
10
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.
