PRODUCT OVERVIEW
The OBD2 diagnostic tester is a portable and easy-to-use vehicle computer tester. The tester works in OBD2
standard (On-Board Diagnostics level 2). The OBD2 standard has been in force for cars manufactured in the
USA since 1996 and since 2001 (EU) or 2003 for cars with a diesel engine (EU). As the power is drawn directly
from the vehicle's power supply system, the device is always ready for operation. The correct, reliable, and
safe operation of the device depends on its proper use, therefore:
Read the entire instructions manual before the fi rst use of the product and keep it for future reference.
The supplier shall not be held liable for any damage resulting from failure to observe the safety regulations and
recommendations specifi ed in this instructions manual. Use of the product for purposes other than those for
which it was intended shall cause the loss of the user's rights to the guarantee and under warranty.

PREPARING FOR OPERATION
The OBD2 standard was developed as an extension of the OBD standard, which is used to perform diagnos-
tics of vehicle systems and to store its results. Some of the diagnostic results are visible to the user in the form
of dashboard lights and/or vehicle computer messages. However, the system stores much more data which
the person using the tester is able to read and, based on it, identify the problem with the vehicle. The tester
presents data in the form of Diagnostic Trouble Code (DTC), which consists of fi ve alphanumeric characters.
The DTC structure is standardised and consists of a letter and four digits. The letter indicates which vehicle
system is aff ected by the failure: B – body, C – chassis, P – motor, U – communication system, the fi rst digit
after the letter indicates whether the fault is general (0) or manufacturer-related (1). The next digit indicates
the subsystem of the vehicle in which the fault has been registered: 0-2 – air/fuel mixture, 3 – ignition system,
