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 components.
Turn the ignition OFF before connecting the VAG501 to or
disconnecting the VAG401 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
10meg Ohms of impedance.
Fuel and battery vapors are highly flammable. To prevent an explosion,
