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 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 Code Reader to or disconnecting
the Code Reader from the vehicle’s Data Link Connector
(DLC).
To avoid personal injury, instrument damage and/or
damage to your vehicle.
