WHAT IS OBD?
Introduction
WHAT IS OBD?
The Enhanced CanOBD2&1 Scan Tool is designed to work on most
Chrysler, Ford, GM and Toyota OBD1 systems and all OBD2
compliant vehicles.
One of the most exciting improvements in the
automobile industry was the addition of onboard
diagnostics (OBD) on vehicles, or in more
basic terms, the computer that activates the
vehicle’s “CHECK ENGINE” light. OBD1 was
designed to monitor manufacturer-specific
systems on vehicles built from 1981 to 1995.
Then came the development of OBD2, which is on all 1996 cars and
light trucks sold in the United States. These systems are part of a
government mandate to lower vehicle emissions. The sophisticated
programs in the vehicle’s on-board computer system are designed to
detect failures in a range of vehicle systems. Diagnostic information can
be accessed through a Data Link Connector test port specifically
designed for this purpose. For all OBD systems, if a problem is found,
the computer turns on the “CHECK ENGINE” light to warn the driver,
and sets a Diagnostic Trouble Code (DTC) to identify where the problem
occurred. A special diagnostic tool, such as the Enhanced CanOBD2&1
Scan Tool, is required to retrieve these codes, which consumers and
professionals use as a starting point for repairs.
The Enhanced CanOBD2&1 Scan Tool provides the additional ability to
retrieve enhanced DTCs from most Chrysler/Jeep, General Motors,
Ford, Mazda and Isuzu vehicles. The types of enhanced data available
depends on the vehicle make.
