1. Safety Precautions and Warnings
To prevent personal injury or damage to vehicles and/or the scan
tool, read this instruction manual first and observe the following safety
precautions at a minimum whenever working on a vehicle:
1. Always perform automotive testing in a safe environment.
2. Wear safety eye protection that meets ANSI standards.
3. Keep clothing, hair, hands, tools, test equi pment, etc. away from all
moving or hot engine parts.
4. Operate the vehicle in a well ventilated work area: Exhaust gases are
poisonous.
5. Put blocks in front of the drive wheels and never leave the vehicle
unattended while running tests.
6. Use extreme caution when working around the ignition coil, distributor

8. Keep a fire extinguisher suitable for gasoline/chemical/ electrical fires
nearby.

necessary.
2. General Information
2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called OBD I) was
developed by the California Air Resources Board (ARB) and implemented
in 1988 to monitor some of the emission control components on vehicles.
As technology evolved and the desire to improve the On-Board Diagnostic
system increased, a new generation of On-Board Diagnostic system was
developed. This second generation of On-Board Diagnostic regulations is
called "OBD II".
