SAFETY FIRST!
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 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 trouble-shooting, 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 com-
ponents. Turn the ignition OFF before connecting the Code Reader
to or disconnecting the Code Reader from the vehicle’s Data Link
Connector (DLC).
To prevent damage to the on-board computer when taking vehicle
electrical measurements, always use a digital multimeter with at
least 10 megOhms of impedance.
The vehicle's battery produces highly flammable hydrogen gas. To
prevent an explosion, keep all sparks, heated items and open flames
away from the battery.
Don't wear loose clothing or jewelry when working on an engine.
Loose clothing can become caught in the fan, pulleys, belts, etc.
Jewelry is highly conductive, and can cause a severe burn if it
makes contact between a power source and ground.
