WHAT IS OBD? 
The FixAssist
®
 Scan Tool 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 scan tool, such 
as the FixAssist
®
 Scan Tool, is required to retrieve these codes, which 
consumers and professionals use as a starting point for repairs. 
The FixAssist
®
 Scan Tool provides the additional ability to retrieve 
enhanced DTCs from most Chrysler/Jeep, Ford/Mazda, GM/Izusu, 
Honda/Acura and Toyota/Lexus vehicles, as well as Anti-Lock Brake 
System (ABS) and Supplemental Restraint System (SRS) DTCs and 
vehicle information. The types of enhanced data available depends on 
the vehicle make. 
The Scan Tool is also compatible with most Chrysler, Ford, GM, Honda 
and Toyota vehicles equipped with OBD1 systems with purchase of 
optional OBD1 upgrade.
