ONLY OPERATE THE TEST IN A WELL-
VENTILATED AREA since the vehicle produces
carbon monoxide, a toxic and poisonous gas,
and particulate matter when the engine is
running.
ALWAYS WEAR APPROVED SAFETY EYE
PROTECTION to prevent damage from sharp
objects and caustic liquids.
ALWAYS BE AWARE OF MOVING PARTS (such
as coolant fans, pulleys, belts) since they spin
or turn at high speeds when the engine is
running.
DO NOT TOUCH HOT ENGINE PARTS to prevent
severe burns. The engine parts become very
hot when the engine is running.
ALWAYS SHIFT THE GEAR TO P (FOR
AUTOMATIC TRANSMISSION) OR TO NEUTRAL
(FOR MANUAL TRANSMISSION) AND MAKE
SURE THE PARKING BRAKE IS ENGAGED.
TURN THE IGNITION OFF BEFORE CONNECTING
OR DISCONNECTING THE SCAN TOOL FROM
THE DATA LINK CONNECTOR (DLC) to prevent
causing damage to the scan tool or vehicle's
electronic components.
ALWAYS USE A DIGITAL MULTIMETER WITH
AT LEAST 10 MEGOHMS OF IMPEDANCE
when conducting electrical tests on vehicles
to prevent causing damage to on-board
electronic components.
NO SMOKING ANYWHERE NEAR THE VEHICLE
when testing. The fuel and battery vapors are
highly flammable.
