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:
•
Ensure that testing environment is safe. Always perform automotive
testing in a safe environment.
• Operate the vehicle in a well-ventilated work area because
exhaust gases are poisonous.
• Wear safety eye protection that meets ANSI standards.
• Do not attempt to operate or observe the OBD reader while driving
a vehicle. Operating or observing the OBD reader will cause driver
distraction and could cause a fatal accident.
• Keep clothing, hair, hands, tools, test equipment, etc, away from
all moving or hot engine parts.
• Use extreme caution when working around the ignition coil,
distributor cap, ignition wires and spark plugs because these
components create hazardous voltages when the engine is running.

2 General Information
2.1 On-Board Diagnostics (OBD) II
• The OBD II system is designed to monitor emission control systems and key
engine components by performing either continuous or periodic tests of speci-
fic components and vehicle conditions.
• When a problem is detected, the OBD II system turns on a warning lamp
(MIL) on the vehicle instrument panel to alert the driver typically by the
phrase “Check Engine” or “Service Engine Soon”. The system will also store
important information about the detected malfunction so that a technician can
accurately find and fix the problem.
Examples of valuable Information:
• Whether the Malfunction Indicator Light (MIL) is commanded ”ON” or ”OFF”.
• If there is any stored trouble codes, which Diagnostic Trouble Codes (DTCs) are stored.
• Readiness Monitor status.
