diagnostic tool. You can easily and quickly monitor, clear a DTC to avoid
the hourly rate charged by car repair shops, but we also recommend
the use of this product for car repair shops or workshops who can
easily and quickly identify a car's technical problem. No battery,
laptop, stand-alone device required to operate the device, powered by
the car through a connected OBD socket. The device can also search,

2. GENERAL DESCRIPTION
2.1 ON-BOARD DIAGNOSTICS (OBD II)
The 1st Generation of Automotive Diagnostic System (OBD I) was
developed and marketed by the California Air Resources Board
(CARB) in 1988, monitoring certain parts of the vehicle and reducing
emissions. The continuous development of technology required
the development of a second generation of diagnostic system.
Abbreviation and designation of the second generation diagnostic
system OBD II. The OBD II system monitors and measures emissions
control systems and main units, such as engine, catalytic converter,
lambda sensor, fuel system..., and monitors their condition. If
the system detects a problem, the OBD II system will turn on the
dashboard lights (MIL), warning the driver with „Check Engine" or
„Service Engine Soon" as soon as. The system continuously saves the
error codes and information about them so that the car mechanic can
easily find and correct the cause of the error after reading it.
2.2 DIAGNOSTIC TROUBLE CODES (DTC)
Diagnostic Trouble Code (DTC) generated by OBD II is a code generated
by the on-board computer and related to problems detected on the
vehicle and built into the memory. The codes can be used to identify
the problematic area and helps locate the problem in the vehicle.
Diagnostic Trouble Code (DTC) generated by OBD II consists of five
characters, alphanumeric characters. The first character letter that
defines the main part of the vehicle. The following four characters
are always numbers that provide additional information about the
location of the DTC, the operating conditions, and the reason of
activation. Below you will find the meaning of each character in the
code.

2.3 LOCATION OF THE OBD SOCKET IN THE VEHICLE:
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic scan tools
interface with the vehicle's on-board computer. The DLC connector is
usually located on the left side of the steering wheel, at the bottom of
the instrument panel. If the socket is not located under the dashboard,
consult the Service Manual or your vehicle's instruction manual for the
exact location. At some European and Asian cars, the DSLC connector
