To avoid personal injury, instrument damage and/or damage to your vehicle; do not use the OBDII Scan Tool before reading
this manual. This manual describes common test procedures used by experienced service technicians. Many test procedures require precautions to
avoid accidents that can result in personal injury, and/or damage to your vehicle or test equipment. Always read your vehicle's service
manual and follow its safety precautions before and during any test or service procedure. Always observe the following general safety
precautions: When an engine is running, it produces carbon monoxide, a
toxic and poisonous gas. To prevent serious injury or death from carbon monoxide poisoning, operate the vehicle ONLY
in a well-ventilated area. To protect your eyes from propelled objects as well as hot or
caustic liquids, always wear approved safety eye protection. When an engine is running, many parts (such as the coolant
fan, pulleys, fan belt etc.) turn at high speed. To avoid serious severe injury, always be aware of moving parts. Keep a safe
distance from these parts as well as other potentially moving objects.
Engine parts become very hot when the engine is running. To prevent severe burns, avoid contact with hot engine parts.
Before starting an engine for testing or troubleshooting, make sure the parking brake is engaged. Put the transmission in
park (for automatic transmission) or neutral (for manual transmission). Block the drive wheels with suitable blocks.Connecting or disconnecting
test equipment when the ignition is ON can damage test equipment and the vehicle's electronic
components. Turn the ignition OFF before connecting the Scanner to or disconnecting the Scanner from the vehicle’s
Data Link Connector (DLC). To prevent damage to the onboard computer when taking
vehicle electrical measurements, always use a digital multimeter with at least 10 megOhms of impedance.
Fuel and battery vapors are highly flammable. To prevent an explosion, keep all sparks, heated items and open flames away
from the battery and fuel / fuel vapors. DO NOT SMOKE NEAR THE VEHICLE DURING TESTING.
Don't wear loose clothing or jewelry when working on an engine. Loose clothing can be become caught
in the fan, pulleys, belts, etc. Jewelry is highly conductive, and can cause severe burn if it makes
contact between a power source and ground.
