LAUNCH

Functions

OBD BOOK can be used to diagnose all the vehicles with an OBD-II diagnostic socket,
to analyze troubles, and to find out the cause and location of troubles quickly and
accurately.
It supports four types of OBD-II protocols (SAE J1850 PWM, SAE J1850 VPW, ISO
9141-2 and KWP2000).
OBD II is the abbreviated form of On Board Diagnostics II. It is a set of standards for
automobile communication protocol initiated by American Automobile Engineering
Association (SAE) and authenticated by the Environment Protection Association (EPA)
and California Resource Association (GARB). The American Government requires that
after 1998, all EFI cars sold to the United States must be equipped with such a
self-diagnosing system.
The development of OBD II has put an end to the inconvenience for car service
caused by different DLCs, different fault codes and different diagnostic functions
adopted by various automobile manufacturers. It provides the manufacturers of EFI
cars with a unified test method, unified diagnostic mode, unified shape of DLCs and
unified installing position. Therefore, with only one tester, the diagnosis can be
performed on various models with an OBD II interface. OBD standard requires unified
16PIN DLC (data link connector) on a car.
