WHAT IS OBD?

WHAT IS OBD?

The Code Reader is designed to work on all OBD2 compliant

vehicles. All 1996 and newer vehicles (cars, light trucks and SUVs)

sold in the United States are OBD2 compliant.

One of the most exciting improvements in the automobile industry was the addition of on- board 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 U.S. Like its predecessor, OBD2 was adopted as part of a government mandate to lower vehicle emissions. But what makes OBD2 unique is its universal application for all late model cars and trucks - domestic and import. This sophisticated program in the vehicle’s main computer system is designed to detect failures in a range of systems, and can be accessed through a universal OBD2 port, which is usually found under the dashboard. 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 Code Reader, is required to retrieve these codes, which consumers and professionals use as a starting point for repairs.

The Code Reader provides the additional ability to retrieve Anti-Lock Brake System (ABS) DTCs from most Chrysler/Jeep, Ford/Mazda, GM/Isuzu, Honda/Acura and Toyota/Lexus vehicles. Refer to Vehicle Applications - ABS on page 32 for vehicles covered.
